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
