File Upload Information
We accept SHP (.shp, .shx, .dbf, and .prj), KML, KMZ, and TAB files.
- Files must be submitted as zip files.
- If submitting SHP data, the zip file should include .DBF, .SHP, .PRJ, and .SHX file extensions only.
- Datum used must be NAD83 or WGS84.
- Metadata should be removed from files prior to upload; only geometry is needed
- Each form submission should be limited to a single station code. Do not submit files for multiple station codes on a single form.
- Ensure all objects/polygons are in one single layer and that your file does not contain multiple layers.
- Merge clustered polygons, multi-object polygons, or polygons intersecting/overlapping with one another to ensure every object in the layer is an individual polygon. Some tools may call this “dissolve.” Multi-object polygons will cause significant performance upload problems.
- Ensure the final zip file is under 155MB.
