Idaho Geographic Information Systems Data
Data available from the Idaho Department of Water Resources conform to the Idaho state cartographic standard, which is Idaho Transverse Mercator, NAD83 (IDTM83). Both IDTM Projection Parameters and a discussion of IDTM are available.
Note: Errors in data are inevitable. While we do our best to produce good data, you might find a problem we overlooked. Please report any errors you find to firstname.lastname@example.org.
Most of the data is state-wide, so they are not appropriate for detailed, site-specific analysis.
