Utah H3 Hexes

Last update · October 2022: Initial creation

Category: Indices Data Type: Polygon GIS data Stewards: UGRC & Uber

The H3 reference polygons covering the State of Utah at resolutions 5 through 9. These were created with the H3 API produced by Uber, Inc and cover the entirety of the state. You can use these for both a standard hexagon grid for the state and a spatial dataset for points aggregated via the H3 API.

See our H3 blog post for an example usage scenario.

A closer look

The H3 Spatial Index , opens in a new tab (created by Uber) helps users aggregate point data using an easily reusable common grid. This allows you to maintain a consistent geometry across all your analyses, which makes them easier to compare. H3 uses highly-optimized math routines to assign lat/long coordinates an ID corresponding to a polygon (almost always hexes) at a given resolution rather than performing a much slower point-in-polygon geometrical operation. Once you've generated IDs for your points, you can use these polygons to aggregate them and display summary statistics on a map.

We used the H3 library to create the index polygons that cover the entire State of Utah at resolutions 5 through 9. You can find more information about how we created them, along with an example of how to use them, in our H3 blog post.

Like the rest of our SGID data, the spatial reference for these polygons is UTM Zone 12N, NAD83. However, remember that your points must be in WGS 84 lat/long in order to use the H3 API to assign them a hex ID.
