Creating a Layer
You can upload your own spatial data to be incorporated to your maps.
To do this, click on New then Layer.
You can upload a single Shapefile or Mapinfo layer or a .zip of one or multiple shapefiles from your computer, via a web address or a cloud service such as Dropbox.
Once successful, you should see your new data layers under My Library.
A new map will also be automatically created with all of the layers you just uploaded. Alternatively, these layers can then be added to other maps.
