What does it do?

NG9-1-1 is dependent on GIS data. Data must be from authoritative sources and meet the new NENA standards.

The Validator checks that you have the mandatory attributes for each layer you are testing, checks your field names, tests the domain values, and ensures that each attribute meets the data type and length requirement.

You can re-upload and check your data as many times as needed until it matches the NENA model.
