In the geospatial context, a thematic is a representation of different values displayed on a map. For example, a thematic can be used to display land zoning classifications on a map.



How to turn on Thematic Values:

  • Under the Legend tab
  • Click the check box beside the land use classification, for example, to turn on the layer in the map. 



How to edit Thematic Values:

  • Click the gear icon beside the particular value, to the left of the checkbox.
  • The Thematic Manager window will open. 



  • Select or deselect the applicable components of the value to view on the map.
