Launching a Value-Added GIS Program, Pt. 2
The integrity of the data selected or developed for use in a GIS program helps determine the quality and accuracy of the
GIS program itself. It's important to have the best data, but it's also important to make sure that the data used is
right for the intended applications. Data collected with handheld a GPS unit with an accuracy of 1-3 meters may not
appropriate for a project requiring survey-grade accuracy, for example. On the other hand, collecting survey grade data
to use in conjunction with hydrographic data mapped at a scale of 1:100,000 is also inappropriate data use, and can
waste resources. Determining what decisions will be made using the GIS can help determine the appropriate level of
accuracy of GIS data.
Once appropriate data is amassed, and the proper GIS software is installed and running, it is important to identify who
in the organization will be using the GIS and how much training they will require. It may be appropriate to add staff
with specific GIS expertise, or identify an outside GIS service provider to supplement the successful use of the
Data Development and Acquisition
Storage and maintenance of GIS data, an effective quality assurance plan, and software maintenance are all integral
parts of managing an ongoing GIS program. When data products are released for sale, or use by the public, metadata
standards must be established and utilized.
Along with identifying the users of the GIS program, it is also important to identify who in the organization will be
responsible for these critical components of ensuring the GIS program's ongoing success and proper use.
Ongoing GIS Management Plan
Periodic review of the GIS program is an excellent way to ensure its ongoing value and functionality. This should
include review of the use, efficiency and future expansion needs for the program. As time passes, many facets of the GIS
program can change and this review helps ensure the program can flex with future needs, data accuracy requirements, and
Let the professionals at AGI ensure successful implementation of your GIS program in every
phase from needs assessment to program management!
