Benefits of the USNG GIS Data Model


The USNG is a national standard growing in acceptance and popularity.


By preserving data density, important features become more prominent. Suitable for bivariate visualizations using color or symbology.


Each area of the Earth can be referenced by multiple grid cells ranging in size from 1m to 100,000m in multiples of 10.

Analysis and Modeling.

Statistical operations and analysis are improved using consistent, uniform geographic areas.


Geographic areas do not change over time, unlike census blocks, zip codes, and others.

Data Transfer.

The unique grid identifier makes it easy to transfer spatial data (even without a GIS).

Data Privacy and Generalization.

Protect sensitive data by aggregation to grid cell.
