GIS & Geospatial Data

The UAL libraries provides geocoding services via Texas A&M. Texas A&M's Geocoding Services provide limited address geocoding on a credit basis for public account holders. If you'd like a large number of addresses geocoded, please contact our Geospatial Specialist.

The Univrsity of Arizona Organizational Portal to ArcGIS online provides geocoding services through the ArcGIS Online World Geocoding Service with your UA account (NetID required to login). Addresses can be geocoded by adding a table of address to your account as a feature layer or through the Geocoder when logged into a desktop software (ArcGIS Desktop or Pro). More information here:

A map projection defines how the spherical shape of the earth is flattened onto a two-dimensional surface. Need to know which projection is best suited for your map? Check Esri's extensive guide to map projections / coordinate systems.

Confused about map projections? Need held deciding which to use? Check this guide to easily preview and filter map projections by their distortion property (equal-area, conformal, equidistant, compromise).

A useful post from Mike Bostock providing interactive visualizations on how projections change distance and area on your map.
