Using Custom KML Geomaps

Visualizer supports custom geomaps. For cases where the built-in geomaps do not provide the geography you need, use a custom map. Custom geomaps are supported using the Keyhole Markup Language (KML) format. Consider the following prerequisites before creating a geomap with a custom map file:

  • Create or obtain a map in KML format that corresponds to the data in the relevant attribute. For example, since there is no standard definition for United States regions, the built-in maps do not support a United States Region attribute, and therefore a custom KML file is needed.
  • The KML file size must be 20MB or less.
  • Visualizer requires that the KML files have the following structure:<kml> <Document> <Placemark> </Placemark> <Placemark> </Placemark> ... </Document></kml>OR:<kml> <Document> <Folder> <Placemark> </Placemark> <Placemark> </Placemark> ... </Document> </Folder> <Folder> </Folder> ... <Document></kml>
