Geographic Information Systems

A History of Innovative Public Service

http://www.unm.edu/~dgrint

History - Early Innovations 1

• DGR began GIS work back in 1979.• Early GIS work was for NM TSB and used

SAS plus ESRI’s first product, AUTOMAP.• Developed the Geographic Road Network

Database (GRNDB) in 1982 using SAS & DISSPLA.

• The GRNDB was a pioneering GIS designed to map traffic crashes.

History - Early Innovations 2

• DGR purchases second ESRI ArcInfo license (#89) in New Mexico for UNM in July, 1984.

• ArcInfo was first used in combination with DGR’s GRNDB for the New Mexico Precinct Boundary Adjustment Project. – Groundwork for 1990 Census and Legislative Redistricting.

• Developed a GRNDB for the Nevada DOT (1987 – 1991).

History - Recent Innovations

• GRNDB and ArcInfo still used routinely along with ArcView and now ArcGIS.

• Developed GIS bases for the most densely populated and urbanized areas of NM.

• NM TSB and DGR have made public the NM Traffic Crash Data Web Page since 1995.

• Participated with other UNM departments – had a ESRI University Site License at UNM since 1998.

Current Focus

• Focus primarily turning data into information.• GIS an important tool that is part of Data

Integration and Data Analysis services we have traditionally provided to state government.

• Staff and students have expertise in spatial statistics, spatial analysis, and location theory - NOT a limited GIS/GIT technology focus.

• GIS has been proven a useful tool for analyzing government data and making the resulting information more accessible to the public.

Current Innovations

• Geographic Access to Health Care – Developing Gravity Model using SAS, ArcView and ArcGIS for NM HPC

Internet based GIS (ArcIMS) for the New Mexico Traffic Safety Bureau.

Internet based GIS (ArcIMS) for census and demographic data in cooperation with BBER and the NM State Data Center.
