Spatial Map Filter

From ProStar Geocorp

The spatial filter allows Transparent Earth users to query for and display layer information within a specific area on the map, instead of the whole map. Users can create spatial views with the following tools:

  • Filter Layers by Circle
  • Filter Layers by Rectangle
  • Filter Layers by Polygon
  • Filter Layers by Current View
  • Clear All Filters

Creating a Spatial Filter View allows users to view specific features only within a defined area.

All records that reside on or inside the boundary line will display. Any record of the same layer that is outside of the boundary will not display.

If a record intersects with the filter boundary line that entire feature will display. For example: If a line touches or crosses the spatial filter view boundary line, the entire line will display.
