Dear Mr. Gilbert:
This is a follow up letter to clarify the previous request of February 2, 3990.
At that time the City of Round Rock requested an estimate for digitizing tax /
appraisal maps for our Extra - Territorial Jurisdiction (ETJ), onto ESRI's PC-
Arc Info Geographic Information System.
The City of Round Rock (1" to 100' maps) encompasses 18 square miles and
12,000 parcels. The ETJ consists of large parcels of 100 plus acre tracts, and
are only available at 1" to 400' scale. The ETJ, including the City of Round
Rock, encompasses 57 square miles and 15,000 parcels. The 1" to 400"
maps are the same quality tax appraisal maps as the 1" to 100' maps.
All of the Williamson County Tax appraisal maps have been created using
both USGS Quad maps, and the 1983 Stackhouse planimetric maps, the later
of which was tent in our earlier request. The Stackhouse planimetric and
USGS maps should act as reference maps to control quality. We shall also
provide index maps of the whole ETJ which details the area of coverage for
each set of maps.
The City of Round will produce copies from negatives of both the 1 "to
100' & 1" to 400' maps in order to provide the highest quality product which to
digitize from. These prints should greatly reduce the error that results from
slippage and stretching.
1.) Digitize a base map which will include the following information:
(Please provide a cost per parcel, for each of the following items, based
on the maps included in this pack.)

b.) Street Center Lines with street naives as shown.
c.) All lakes, creeks and waterways.
d.) Railroad R.O.W. and tracks.
e.) Because of the limitations associated with PC -Arc Info and
the size of the City of Round Rock, we request that the base
map coverages be broken down into sheets based on our 1"
to 400' appraisal maps. (These sheets should be edge
matched to adjoining sheets, but left separated. This will
allow the City to join the sheets together into a manageable
size for PC - Arc Info.)
2.) The City of Round Rock still requests a time schedule, presuming an
April 1st start date, which you will be able to follow If selected.
3.) The City is also able to provide the following maps if required:
* Our 1" to 800' map to provide an overview of our ETJ, which you
received with our previous request.
* Our 1" to 1,200' map to provide an overview of our ETJ.
* A complete set of ETJ maps containing the Stackhouse
Planimetric maps. (Examples have been sent with previous
requests.)
* USGS maps may be available at 1" to 400'. These enlargements
were used in the creation of the tax appraisal maps.
4.) As before, the City of Round Rock requests:
* A list of references of past digitizing, for Are Info, and only for
urbanized areas. (ie. parcel data.)
* A copy of your standard contract so that when we select a
contractor a final contract can be drafted immediately.
We have extended the response date until Friday, February 23rd, 1990 for
your proposal. Feel free to contact me at (512) 255 -8612, FAX =(512) 255

Section 1:
Introduction
Executive Summary
Analytical Surveys, Inc. (ASI) is known for its people who understand its
client's problems and deliver solutions. In keeping with our Total Quality
commitment, we take pride in our ability to communicate well with our
clients to meet their needs. During the past few weeks, ASI has been in
contact with the City of Round Rock to obtain a greater understanding of
the City's needs, to better understand the current problems and to assist
the City in solving these problems effectively and efficiently. We feel that
frequent communication is vital to successful projects, and expect to in-
crease such interactions if awarded this contract.
Cities, counties, municipalities and other entities similar to the City of
Round Rock are beginning to recognize the true value of an accurate
Geographic Information System (GIS) that is customized to meet their
needs. To meet this growing need, ASI integrated a special map conver-
sion department into its GIS database development capabilities. In con-
junction with photogrammetric processing, editing and scanning, we
created a unique department designed to merge a variety of source data
with extensive computer data to complete a GIS. On this project with the
City of Round Rock ASI will utilize its experience to combine existing
hardcopy source and computer data to create a GIS for the City.
Our personnel are experienced in digital photogrammetric mapping, GIS
database development and implementation, data conversion, and file
translation. Virtually all of our projects are compiled using ASI's inter-
nal, binary (basic computer format) system. This system provides en-
hanced consistency in project data and greater processing power. The
computer can manipulate, display and process the data faster, easier and
more accurately that traditional manual methods.
We have extensive experience in both ARC/INFO and parcel mapping.
The City of Round Rock will benefit from our capabilities in the following
areas:
• ARC /INFO Experience -- ASI has extensive experience with
ARC/INFO, which was installed in August, 1987. ASI is involved
with the following major contracts, all of which chose
ARC /INFO as their software system:
o Alhambra, CA. (as subcontractor to ESRI)
o MSD, Louisville, KY.
o Stockton, CA.
o Burbank, CA.
o Johnson County, KS.
Analytical Surveys, Inc. -A TOTAL OIJALIT( COMPANY February 23, 1990
City of Round Rock GIS Project 2
General Business
o Colorado Springs, CO.
o Loudoun County, VA.
ASI was, or is currently, under contract with the above clients to
deliver the digital data in ARC /INFO format. In 1988, ASI
wrote its own proprietary translator from the Intergraph IGDS
system, which manages attribute input, to ARC /INFO. This
translator bypasses the Standard Interface Format (SIF) and is
therefore very efficient. Further, unlike other commercially
available translators, ASI's software accurately translates at-
tribute data.
ASI is committed to its ARC/INFO investment and has now
been working with ARC /INFO for over two years. The learning
curve normally associated with inexperienced ARC /INFO users
is not a factor for ASI's clients.
• ARC /INFO Beta Site -- ESRI recently appointed ASI as a beta
site for all future VAX -based ARC /INFO releases. We feel that
this appointment, in conjunction with ESRI choosing ASI as a
subcontractor for the Alhambra, California, project, shows
ESRI's confidence in ASI's ARC.`INFO knowledge.
Project references and client contact phone numbers are in-
cluded in Appendix A.
• Equipment and Software: ASI invests extensively in equipment
and Research and Development efforts and has gained sig-
nificant increases in productivity through technological advance-
ment. ASI's proprietary software automates many procedures to
ensure efficiency, accuracy and consistency of client's data. In
addition, ASI's data translators provide accurate data transla-
tion to clients' systems (e.g., ARC/INFO, AutoCAD, Intergraph,
MOSS). Please see Appendix B for more details.
• Personnel: ASI's well trained staff is highly rated by client
project managers in technical ability and performance. All of
ASI's production staff complete a probationary three month
training period, incorporating ASI's stringent quality control pro-
cedures and processes, Total Quality commitment, and personal
and product integrity into daily production. John Thorpe, Presi-
dent, continues to emphasize training and quality in ASI's team -
oriented production environment. Please see Appendix C for
resumes of key personnel.
ASI maintains its main production and administrative headquarters at
1935 Jamboree Drive, Suite 100, Colorado Springs, Colorado, 80920,
telephone number (719) 593 -0093. ASI's Southeast Division (SED) of-
fice, also a production facility, is located at 1279 Kennestone Circle, Suite
600, Marietta, Georgia, 30066, telephone number (404) 426 -4066.

Section 2:
Technical Approach
The following is a discussion of the procedures that ASI will use to cap-
ture the required data and build the PC ARC /INFO database. This dis-
cussion should be useful to the City of Round Rock in understanding
ASI's approach to accurate and complete data capture. Please note that
while these procedures represent the proposed approach, the procedures
can be modified during negotiations to ensure that the City of Round
Rock's identified requirements are met 100%, the first time.
In keeping with ASI's Total Quality philosophy, we anticipate working
closely with the City in the early stages of the project to ensure all require-
ments defined in the contract are clearly understood by both parties.
This includes definition of all detailed specifications, and of client and
ASI responsibilities throughout the course of the project.
During the start -up phase, ASI will work with the City to define the
database requirements. As a result of this analysis, ASI will write a
Database Design document clearly specifying all map features, all as-
sociated attributes, and how they are integrated in the PC ARC /INFO
database. The document will define specific coverages, provide all as-
sociated INFO item definitions for attributes, and define any annotation
to be associated with the coverage. Feature codes for each feature will
also be assigned.
ASI will deliver this document to the City for review, and will incorporate
the necessary modifications in a Final Database Design document. This
final document will serve as the basis for all subsequent data capture pro-
cedures.
Once the Database Design documentation is finalized and approved, ASI
will commence database development. In beginning this process we
strongly recommend, where possible, that the parcels data be rectified to
the planimetric base. To accomplish this, we will graphically adjust the
parcels data to the accurate Stackhouse data to create a more accurate
parcels layer. Where Stackhouse maps are not available, ASI will ensure
that all maps tie together at the sheet edges.
Analytical Surveys, Inc. - A TOTAL QUALITY COMPANY February 23, 1990
City of Round Rock GIS Project 5
The graphic rectification of the parcel data will be accomplished by high-
ly skilled, experienced technicians. These technicians will use their judge-
ment to graphically adjust each of the layers to be rectified to the features
specified. ASI recommends the following features be used in this "best -
fit" process:
Street Pavement Edges Street Names
Curblines Fence Lines
Building Footprints Railroads
Hydrology Bridges
Reference Grid
Adjustment tolerances for best - fitting parcel data will be defined during
negotiations to ensure that the City of Round Rock is satisfied with the
results. Any anomalies outside of these tolerances will be brought to the
City's attention.
It must be noted here that ASI has used a number of "high -tech" methods
to graphically adjust data to an accurate base and has determined that no
other technique can fully and efficiently utilize the human abilities, judge-
ment and experience usually needed for the subtleties of such adjust-
ments. This method of graphic adjustment, best - fitting to the plarimetry,
ensures that features are correctly placed relative to each other and that
anomalies are detected and resolved with the client.
There are several methodologies utilized in the industry to accomplish
the objective. These are: 1) Coordinate Geometry (COGO) data entry,
2) Redrafting on an orthophoto base before digitizing; 3) Rubber sheet-
ing after digitizing; and 4) ASI's preferred method of graphic adjustment
to the planimetric base.
ASI has experience in each of these methodologies, and as a result, has
determined that its preferred method is superior to the others, even
though it seems less "high- tech ". As noted, ASI relies on experienced,
highly skilled staff to perform the task. Each method is identified and
briefly discussed below:
• COGO data entry is very expensive in that each angle and length
of each lot line is key- entered. Data errors and omissions are
frequent, requiring additional best -fit efforts which add to the ex-
pense of this procedure.
• Redrafting data onto an orthophoto and then digitizing them is a
frequently used procedure. However, the redraft is an extra step
that may actually introduce drafting errors in addition to original
data errors.
Analytical Surveys, Inc. -A TOTAL QUALITY COMPANY February 23, 1990
City of Round Rock GIS Project 6
• Rubber Sheeting is a process whereby a map is digitized and
then mathematically transformed to fit the shape of the
planimctry. All of the data are proportionately moved to fit the
new shape, which often results in inaccurately placed data be-
cause of insufficient control.
• ASI's recommended approach, with several years of successful
experience, is to obtain plots of the planimetric map on trans-
lucent paper, with coordinate ticks for registration, at the same
scale as the source map to be digitized. A translucent, stable,
destructible copy of the source map is overlaid on a light table.
A skilled technician then carefully fits each area, block by block
(or even portions of blocks when necessary) to assure that the
data fit the very accurate planimetric base map.
ASI's graphic adjustment method is the most efficient for ASI and is the
most easily checked by the City. Very good results have been attained on
all of the work done using this methodology. Please remember that ASI
has the ground truth of very accurate planimetric maps to graphically ad-
just the source data, and the experience of its highly skilled technicians to
make the judgement calls. None of the other techniques can fully utilize
such experience.
After using our graphic adjustment procedures to rectify the data to the
appropriate base features, the data are digitized on our accurate digitiz-
ing tables using ASI's proprietary DIGIT software. In conjunction with
APS proprietary software, personnel, equipment and experience combine
to form a smooth controlled procedure of digitizing, processing and edit-
ing. We utilize accurate digitizing tables (please refer to the Equipment
List in Appendix A), APS, and interactive graphic workstations in provid-
ing accurate, smooth, concise data.
Once the parcels have been rectified to the base (where Stackhouse data
exist), the data are digitized. All data will be registered consistently in
the modified Texas State Plane Coordinate System. ASI's custom trans-
lator ensures that TICS are consistent for each coverage within a tile.
ASI's Digitizing Technicians are experienced in capturing all of the types
of linework required by this contract. We pride ourselves on our very ac-
curate digitizing capabilities. The technicians will ensure that straight
lines are two -point digitized, and that curved lines (e.g., rivers) are cap-
tured to reproduce the smooth curves presented on the source. (Unneces-
sary vertices are removed by proprietary software discussed below.).
Further, ASI's proprietary DIGIT software allows attribution to be per-
formed during initial linework digitizing, while also minimizing keystroke
errors. This is far more efficient than traditional two -pass techniques,
and ensures that the correct attributes are placed on the correct map fea-
tures. Technicians also capture repetitive data only once, modifying it
Analytical Surveys, Inc. -A TOTAL QUALITY COMPANY February 23, 1990
City of Round Rock GIS Project 7
only where it changes. This minimizes keystroke errors. For example,
within a Tax Appraisal map, the Subdivision and Section may both stay
the same and will be keyed in only once. The Block will be keyed in as it
changes, and Lot numbers will be keyed in for each polygon. The
software ensures that the repetitive data is correctly attached to each
polygon.
Next, the digitized data will be plotted on a Versatec Electrostatic Plotter
for close examination by the Digitizing Technicians. To perform this edit,
the technicians overlay the captured data to the source to ensure that all
linework is captured within tolerances (i.e., all linework is present and
captured correctly, no whitespace exists between digitized data and the
source, and curves are captured appropriately). These technicians also
check attributes to ensure that they are correctly captured. The Digitiz-
ing Technicians then make corrections to the digital data as needed.
ASI's Processing System (APS) software, the next step in our methodol-
ogy, functions as an umbrella to a series of intricate and carefully
developed software routines designed to manipulate the data efficiently
and effectively through computer processes. These processes perform
complex snapping, edgematching, thinning and quality control functions
that ensure high quality products.
In Processing, the data are passed through numerous programs resident
in APS. Digitizing errors are automatically circled in red, parcels, center-
lines, waterways, etc. are "snapped" within a specified tolerance and
sophisticated edgematching routines examine the data in surrounding
tiles and snap data together to ensure good edgematching. APS also en-
sures data are moved only once. These are only a few of the significant
"cleaning" and smoothing processes that take place during APS process-
ing. The output of APS is in Intergraph DGN (Design File) format to
allow accurate, efficient editing on Intergraph Workstations.
The output of APS is plotted for an internal manual edit. Plots are
created so that all features, attributes, annotation, and coding can be
edited by ASI's experienced Manual Editors. At this time edgematching
is rechecked. The Editor's modifications are then made to the digital
files on an Intergraph Graphics Workstation by a Graphics Editor.
Next, the data are translated to ARC /INFO. As noted, because ASI has
many ARC /INFO contracts, it has written a proprietary DGN-TO-ARC
translator that has many automatic features built in to ensure correct,
complete translation of all graphics features and associated attributes.
This software will be first run on the Intergraph computer files in Validate
mode to perform preliminary checks to ensure all features in the file are
identified in the translation tables, to detect dangles, and to detect any
other Intergraph -file errors. The translator is then run in Translate mode

to perform the actual translation. This is the first point in the process
that ARC /INFO - specific errors can be detected (c.g., polygon label er-
rors). Such errors are discussed below.
This software is very flexible and considers many ARC /INFO specific
problems that are often overlooked by our competitors. For example, this
software allows ASI to specify the CLEAN and MATCHNODE toleran-
ces for each coverage (e.g., .000001), allowing TIC ID values to be
specified to ensure the TIC IDs are identical between adjoining sheets,
and to ensure consistent assignment of TICs between coverages within
the same geographic tile. Further, the translator creates a log file for
each file translated showing all ARC /INFO errors detected, such as if a
CLEAN fails, if any polygon label errors are detected, if any dangles are
present for polygon coverages, if any attribute values are out of an accept-
able range, etc.
The log files also provide summary counts of how many Points, Lines,
Labels, and Annotations exist in the files. These log files are used by our
Graphics Editors to correct the DGN files, and re translate. The DGN
files are updated, rather than the ARC /INFO files, to ensure that files are
only CLEANed one time, and to ensure integrity between the DGN file
and the ARC /INFO coverages, in case the DGN Files are ever needed in
the future.
In addition to ASI's generic DGN-TO-ARC translator, custom modules
will be written for this contract to perform the specific functions required
for this contract.
The translator automatically defines and populates all attributes in the
FAT files and any "relatable" INFO files that are to be generated, ensuring
consistent file definition for all coverages. Further, the software allows
automatic range - checking of attributes.
To ensure all data are correctly translated, every coverage in the initial
tiles will be interactively examined on a PC ARC /INFO workstation by a
trained ARC /INFO technician and the Project Manager. Note that this is
in addition to the computerized checks performed by the translator. All
INFO attributes associated to each coverage in these initial files will be
examined to ensure correct definition, data capture and translation.
While the translator automatically detects all polygon label errors and
polygon node errors, additional interactive checks will be performed to
ensure that translation tables are set - up correctly.
Once ASI is convinced that the software and tables are working correctly,
and once the City concurs after checking the initial data files, interactive
checks at the ARC /INFO workstation will be performed randomly on
several coverages for each delivery. However, every coverage that is

Information
delivered will be computer- checked by the translator, and every log file,
without exception, will be examined by a Graphics Editor, Technical Su-
pervisor or Project Manager to ensure translation is successful and no er-
rors exist. ASI has had a great deal of success with this approach, and is
confident that it will meet the City's needs. However, ASI is interested in
meeting The City of Round Rock's requirements 100% the first time,
every time. Therefore, we are very willing to discuss additional precau-
tions that the City feels may be necessary to ensure satisfaction.
Finally, after all post - translation edits are performed, and all log files are
checked, ASI will use ARC /INFO's EXPORT format to write the
coverage data to tape or floppy disk, as required by the City.
ASI has long recognized and adopted the tenet that it is far more efficient
and cost - effective to capture data correctly the first time, than it is to re-
do work. We are committed to meeting The City of Round Rock's iden-
tified requirements 100 %, the first time, every time. Thus, ASI
understands that it is responsible for correcting and delivering all data
failing the contract requirements.
Additional information is provided below on specific items in ASI's
methodology. These are simply items that many of our clients have had
concerns about, which we have not previously discussed in this document.
Hardware:
ASI's Hitachi Digitizing Table's accuracy, based on manufacturer's
specifications and internal tests, is .005 inches or better.
ASI's procedures to ensure this equipment is correctly calibrated are in-
herent in ASI's production methodology, and are performed on every file.
As Digitizing Technicians register sheets, they examine the RMS errors to
ensure that it is well within specifications. Then, as the data are
processed by APS, edits are done to ensure no data shifts have occurred
(e.g., that could be due to digitizer board calibration). Any errors
detected stop further processing. Further, ASI has Hitachi calibration
software to pin -point any board errors detected.
Project Management and Quality Control:
ASI uses a variety of Project Management tools for tracking project
materials and status through the course of production work. Also, ASI
Analytical Surveys, Inc. • A TOTAL QUALITY COMPANY February 23, 1950
City of Round Rock GIS Project 10
often adopts tools or techniques our clients are comfortable with to assist
joint management. ASI's use of such tools can be discussed during
negotiations.
Typically, ASI utilizes Lotus 1 - 2 - 3 software to develop Gantt Charts to
schedule internal and client deliverables. This serves as a starting point
for the development of other custom - designed graphics tools used to
track the status of each deliverable. ASI has developed a'pie chart" sys-
tem where a plot is created of each delivery. The "pie" for the delivery is
divided up into the individual tasks that are required to complete the
deliverable, such as Rectification, Digitizing, APS Processing, Manual
Edit, Graphics Edit, and Translation. The required completion date for
each task is included. As each task is successfully completed for the
delivery, it is shaded in the pie chart in a color -coded sequence. This
provides an efficient and effective method of recording progress
throughout the course of the project and provides a quick visual status
check. This allows Project Management to quickly discern and rectify any
bottlenecks that develop.
Also, for each of the high -level tasks listed in the pie chart, a checklist is
developed, in tabular format, to list each of the specific sub -tasks neces-
sary to complete the pie chart's task. For example, for the Translation pie
chart task, a checklist is developed that includes each step necessary to
successfully complete the Translation task. These would include Valida-
tion, Correction of Dangles, Correction of Polygon Label Errors, Re-
Validation, Translation, Checking the Log Files, Checking the ARC /INFO
coverages, Exporting the Files, Checking the Export Log File, Writing the
.E00 Files to Floppy Disk, etc. The task cannot be checked off in the
checklist until it is successfully completed. For example, if the re valida-
tion shows that validation errors still exist, that step is not checked off
until successful re- validation is performed with no errors. Thus, another
quick visual check is available for each sub -task required to meet the
deliverable.
Samples of both the Pie Chart and a typical Checklist are provided in Ap-
pendix F. Please note that these are custom - designed for each project.
ASI's GIS Department also has a "card catalog" system to track client
source documents, internal check plots, add all other project materials.
This system "points" to the various flat files, map racks, tape racks, etc.
Thus, if the Project Manager has a question on the current delivery and
wants to see the internal checkplots, he /she can easily determine from the
card catalog where those plots are kept. This allows ASI to easily and effi-
ciently track the physical location of all project materials, and ensures
these are not lost in the shuffle of production.

ASI's Quality Control mechanisms are built into ASI's entire production
process, with a variety of computer and manual checks at each step. As
stated throughout the descriptions of ASI's procedures, the quality of the
data and the requirements of the City are paramount. ASI will provide
data that meets the City's requirements 100 %. Also, any additional
quality assurance steps that the City would like to add to the process can
be discussed during negotiations.
Registration Between Layers:
As noted in the Procedures, ASI's translator automatically assigns identi-
cal values to the TICs for all coverages within a given tile. This is done
via TICs that are digitized into the Intergraph files. This also allows the
TIC -ID to be assigned identical values for adjacent tiles, ensuring con-
tinuity. ASI's accurate registration and digitizing software ensures that
RMS errors are always well within the client's requirements.
Smoothness and Conciseness:
APS allows table- driven "thinning" to be accomplished. On curved lines,
Digitizing Technicians use as many vertices as they feel are necessary to
capture the true shape of the line. APS then omits any unnecessary ver-
tices while still maintaining the smooth curves of the lines. Digitizing
Technicians capture straight lines via two -point digitizing whenever pos-
sible.
Pseudonode Removal:
ASI has written proprietary software to remove pseudonodes from
specified ARC /INFO coverages. This software module is automatically
invoked by the Translator for the specified coverages, and ensures that
such unnecessary data are removed.
Closing:
Utilizing the procedures, quality control checks and technology described
above, ASI ensures that the City of Round Rock will receive the quality
and value it expects.
