Example http://localhost:8080/rest/EnterpriseMapping/LegacyMapTilingService/getTile- Bounds? name=/NamedTiles/WorldTile &level=4 &row=1 &col=1 &output=json convertScreenToMapCoord 34 Description Converts a specified set of screen pixel coordinates to coordinates in the map's coordinate system, and returns them. Parameters For information on the parameter types listed below, see Request URL Data Types on page 46. Parameter name Type String Required yes Description Specifies the name of the named map for which you are converting coordinates. MapInfo Spatial Server 1.0
Parameter level screenX screenY view output Example Type Integer Integer Integer Bounds String Required yes yes yes yes yes Description Specifies the map zoom level. This parameter must be set to a value greater than or equal to the minLevel value and less than or equal to the maxLevel value for the named map.
