XY Coordinate Validation Rules for Idaho

The following extents are based upon Hydrologic Units Fourth Code (Hydro_HUC4) projected in NAD83 Idaho Tranverse Mercator meters.

 

UTM XY Coordinate Validation Rules for Idaho GIS data per HUC4 intersecting Idaho

Northing:

The value for the Northing field must be an integer between 1,000,000 and 9,999,999.

In Idaho, we can narrow that down further (if we want) to ?

 

Easting:

The value for the Easting field must be an integer between 100,000 and 999,999.

In Idaho, we can narrow that down further (if we want) to ?
