Ken Tozier is founder and
CEO of International Computer Works (Temple Terrace, FL).
Wyoming is among the first states using GIS to
update digital maps for the U.S. Census Bureau's TIGER files. Census map
information is distributed to the state on CD-ROM. Clerks in each of 23
counties then upload the files, make updates, store the revisions on diskettes,
and send them to a central GIS coordinator. The changes are then compiled into
a single file on a CD and sent to the Census Bureau where the changes are
uploaded to the TIGER database. Obviously, this new system required that clerks
in each of the counties be well trained in the updating procedures and the
software used to update the files.
In August 1995, the state of Wyoming
awarded a contract to International Computer Works (ICW, Temple
Terrace, Florida) to provide a
set of software products and services for the statewide Wyoming County Clerks
geographic information systems (GIS) project.
The Request For Proposal (RFP) for the project was issued by Secretary
of State Diana Ohman; it stated, "The main purpose of the County Clerks
GIS project is to maintain the TIGER 94 data from the U.S. Bureau of the Census
through the year 2002 in preparation for the 2000 Census, TIGER 2000, and
legislative reapportionment for the state of Wyoming in the year 2002. The
desire of the state is to have each county update and maintain the data and
then have [the data] centrally collected, so that one contact point can then
work with the Census Bureau to send the enhanced data back and forth between
the state and the Census Bureau."

County
training involved individual attention and hands-on experience.
Among the requirements for the
Wyoming County Clerks project award was a statewide training strategy.
Representatives from the 23 county clerks' offices had to become skilled at
editing and updating the TIGER/Line files. Issues critical to the training plan
included economy and an ability to address the needs of an audience consisting
of predominately first-time GIS users.
GEARING UP
Twenty-five workstations were purchased: one for each of the
23 counties, one for the Secretary of State's office, and one for the project
manager. The hardware selected included Pentium 120s (Intel, Santa
Clara, California) with l7-inch
monitors running Windows (Microsoft, Redmond, Washington)
operating systems. Each unit had 16 megabytes of RAM, a 1.0 gigabyte disk
drive, and an internal tape backup unit. The software included MapInfo (MapInfo,
Troy, New York),
along with TMT TIGER Update Edition (ICW), which consists of three components:
TIGER to MapInfo Translator (TMT), MapEdit ToolKit, and MapInfo to TIGER
Translator (MTT).
MapInfo is a general purpose GIS
application that performs mapping and GIS-related tasks. The software's
features and functionality extend well beyond the initial requirements of the
TIGER update project; however, the specific steps used in the workflow for
performing each type of edit are not defined. The MapEdit ToolKit is a MapBasic
application that appears as a seamless addition to the standard MapInfo menu
bar. MapEdit is specifically designed to guide users through the editing
workflow to turn repetitive tasks into standard procedures, perform preedit
validation, and manage multiple tables transparent to end users. Additionally,
the toolkit manages changes to the feature information necessary to maintain
the integrity of TIGER topology such as Version, TLID, sequence, sum values,
and so forth.
The logistical challenges to
designing the training strategy included the vast area to be covered - Wyoming
is almost 98,000 square mile and its population is less than 500,000. Approximately 75 people from 23 counties
needed to participate in the training. This group represented a diverse range
of computer skills and experience in using Windows and GIS and knowledge about
TIGER/Line files. The experience level ran the gamut from first-time Windows
users to skilled GIS analysts, with the majority of experience limited to such
traditional PC applications as using word processors, spreadsheets, or
databases.
During the project's implementation
phase, the 1995 Block Boundary Suggestion Program (BBSP) version of the TIGERs
were released. Also, automated participation in the BBSP or Census
Redistricting Phase I (Public Law 94-171) had to be added to the MapEdit
ToolKit and included in the training plans.
PROGRAM REQUIREMENTS
With this information, the ICW team outlined the following
requirements for the program.
- Because
of the size of the geographic area, regional classes would be conducted to
minimize travel for participants and keep class sizes small enough to
provide individualized training.
- Each
class needed to be completed in three days.
- To
ensure hands-on training, workstations would be distributed at the
training sessions. The sessions
would introduce users to the hardware and establish a level of Windows
literacy among all participants that would allow them to cross over the interface
threshold and use the target applications.
- Participants
would be instructed about MapInfo usage to the extent necessary for
success in the functional areas required by the TIGER Update Project,
specifically using MapEdit ToolKit. The MapInfo training would be
conducted as a prerequisite to any additional map training.
- Instructors
would communicate enough information about TIGER/Line to give users a
sense of the relationship between the various record types they were
updating. They would also provide insight to the topology of TIGER versus
MapInfo.
- Instructors
would provide an understanding of what the BBSP entailed along with the
specific steps for compliance. Attendees would be taught to use the
translators "TMT in" and "MTT out." Participants should become MapEdit
experts - not experts in Windows, MapInfo, TIGER, or BBSP. They had to be
experts in the use of the MapEdit ToolKit.

Fortunately, the ICW team was not
alone. The Secretary of State's office provided logistical support and the
services of Richard Memmel - GIS coordinator for the information technology
division - as project manager. The U.S. Census Bureau provided people for
several classes who were knowledgeable in TIGER or BBSP, and MapInfo conducted
a special one-day "Introduction to MapInfo" course for each of the
training sessions.

Working with the Secretary of
State's office in Cheyenne, we were
able to secure four excellent training facilities, one in each of the four
comers of the state - Cheyenne,
Gillette, Powell, and Rock Springs.
Most of the attendees traveled to these sights one day in advance and came to
class ready to begin by 8:00 a.m. on
the first day of class.
DAILY SESSIONS
Because of the regional nature of the training sessions,
five to seven counties attended one or more of the classes. Each county was
represented by one to three people. Several counties attended more than one
session. Each of those counties brought their workstations with them to maintain
the hands-on orientation of the training.
Prior to the training, Memmel and
an assistant organized and set up the workstations. The morning of the first
day, he provided participants with the necessary introduction to the hardware
and a brief overview of the Windows interface.
Knowing what MapInfo skills were
necessary to effectively use the MapEdit ToolKit, the ICW team recommended the
content for what became a one-day "Introduction to MapInfo" course. A
MapInfo trainer then prepared the class for two days of MapEdit ToolKit
training by ICW personnel. The MapInfo training typically commenced by 9:30 a.m. and ran through the first day, which
ended well after 5:00 p.m.
Secretary of State Ohman was
present the first day of each class, delivering a kick-off message for each of
the respective groups. In speaking to the county clerks about the GIS
reapportionment project, Ohman said, "This is an important project,
important to our state, and important as a model for other states to follow. We
are the only state tackling this project [together] and it is an opportunity
for Wyoming to be a leader."
On the morning of the second day,
the ICW trainer and the representative from the U.S. Census presented a
discussion about the structure of TIGER/Line. This helped the attendees
understand the differences between TIGER topology and MapInfo topology.
The balance of the morning revolved
around demonstrating the MapEdit ToolKit and how each of the editing functions
were intended to be used. ICW provides TIGER/Line files of the city of Manassas,
Virginia, along with a spatially
correct backdrop with the update. These files are used in training along the
tutorial-based documentation that accompanies the update software. The
afternoon training consisted of hands-on use of the three modules that make up
the TMT's Update edition with specific emphasis on the ToolKit. By the end of the second day, all of the
participants were proficiently editing TIGER/Line files. Before leaving class
that afternoon, the batch translation of the TIGERs for each of the attendees
was initiated.
The results of the translation
provided the attendees with their own county data ready for use in training on
the third day. After a brief review of the material covered in the two
preceding days, the third day of training was spent editing their own 1995
TIGER/Line Files. This approach allowed the instructors to move from
workstation to workstation offering assistance on an individual basis. At the end
of the third day of training, representatives from each of the counties packed
up their new workstations - loaded with their own county data and ready for
updating.
These training sessions were
conducted in the months of September and October 1995. In
March 1996, two advanced courses were taught - one each in
Lander and Casper. Representatives
from each of the counties returned with their workstations and edits in
process. Again, hands-on training was an important component.
The Wyoming
project manager and representatives from the U.S. Census and ICW conducted the
training in the March sessions. Representatives from the Denver,
Colorado, office of the U.S. Census
addressed issues pertaining to BBSP, while the balance of the sessions focused
on advanced editing, quality control issues, and individual attention to each
county team.
ICW and Wyoming's
project manager are providing ongoing technical support to the county clerks.
On several occasions, workshops have been conducted by the Wyoming
project team. This approach to support and training will continue into the
foreseeable future with the Wyoming TIGER Update Project.
With good hardware, software,
training, management support, and - most importantly - a dedicated group of
participants, our national treasury of digital geography with attribution is
being updated one county at a time in Wyoming.
