Key Decisions
Initial Software
Public Access to data. Never “marketed” GIS
Quality of data – accuracy builds confidence
Build on small steps and successes
New software – can be the needed key, or suicide
Data stewardship concept. Builds ownership
Organizational focused GIS vs. departmental
Build a broad base of support for the system
Training and ongoing support are imperative
Automation of routine processes is critical!

Why use GIS?
Geographic or location base to most city information and
services (FGDC study 80% gov’t data location based).
Better information and analysis tools for decision making
and communicating.
Same information to everyone not different versions, dates.
Public access to information
History of changes (Measure 37)
Dynamic resource information increasing, improving
Data + Mapping production of custom maps
-- Better Customer Service!
