Supported file types and their requirements

File types

MakeMaps supports multiple file types to simplify your map making process so that you won't need to manually convert files from one format to another.

Spreadsheet file types - XLS(X), CSV, ODT...

Currently the spreadsheet files are required to have their location data in two separate columns. For example:

Data 1	Data 2	Lat	Lon	Data 3
some	data	120	446	etc.

• Headers are required.
• Do not use numeric headers, like "1", "2".
• Headers like "1Column" and "Column1" are allowed.
• You can rename the columns later in the editor.
• Only the first sheet of a spreadsheet document is processed

Spatial data types - GeoJSON, OSM, KML, WKT, GPX

These datatypes will work out of the box, with no other requirements than that they are valid.

• GeoJSON files can be validated at GeoJSONLint
• WKT files can be validated at Wicket
