Preferred File Types for GDU (Geo Data Upload)
.SHP (Shapefile)
Submit required file extensions (at least the .shp, .shx, .dbf, and .prj) in a .zip file (zipped file)
.CSV
(Comma Separated Value): Submit data separated by commas, with each column surrounded by quotes. Header row and spatial attributes (latitude & longitude coordinates) are required.
.KML/.KMZ (Keyhole Markup Language): Represent the data as SchemaData and SimpleFields (preferred) or ExtendedData.
.JSON/.GeoJSON
Important to Note:
We don’t accept JPG, PNG, PDF, Geodatabase, AutoCAD file, MrSID, or MapInfo TAB. Most software has an option to convert to SHP or CSV so you can export into an accepted format.
File size limit: 100MB
Geometry
Please provide clean geometry with:
No Dangling lines
No Undershoots
No Overlapping lines or nearly overlapping lines
No Polylines for polygonal features such as political boundaries or parcels
No Overlapping polygons
Features with the same name or containing the same feature are represented by a single polygon rather than multiple polygons.
We accept Inner loops/donuts
E.g., to exclude lakes or rivers from a forest
Polygons should have correct windings, and they must not self-intersect
Our preferred order is clockwise for both internal and external polygons
