Describing the data source

Before you upload source files to Maps Engine, ensure that each file conforms to the specifications listed in Supported data formats and limits. Each main file must be accompanied by all required associated files. As an example, if you are uploading a shapefile (.shp), you'll need to select its associated .shx and .dbf file; look for other files that have the same filename as the main file, but with different extensions. It's critical that data is formatted properly before upload. 

Note: When you upload vector data, Maps Engine transforms it to a format called vector table.

These are the fields that you need to fill in when uploading data sources.

Your organization might have a standard naming practice. If it doesn't, think about creating one for yourself. In some views of the map data catalog, especially the thumbnail view, there is limited space; consider consider whether the name is identifiable if only the left-most characters are visible. A name can contain alphanumeric characters and spaces.

The name of a data source need not be unique in the Maps Engine catalog.
