Finding Quality GIS Data

Try out the Data Finder! A centralized resource to support the UC community.

Once you’ve identified potential data sources, consider these factors when evaluating datasets:

Data Quality Checks:

  • Government Sources: USGS, Census Bureau, NOAA, state and local agencies
  • International Sources: UN data portals, OpenStreetMap, Natural Earth

Tips for Success:

  • Start with broader searches and narrow down based on your specific needs
  • Pay attention to licensing and usage restrictions
