Description

OdDbGeoMapPE sample implements the OdDbGeoMapPE class functionality. The sample implements the updateMapImage() method for updating a geo-map object.

The updateMapImage() method works correctly only when using the WORLD-MERCATOR coordinate system for a geo-data entity and when OdDbGeoData::TypeOfCoordinates is not equal to kCoordTypLocal.

The geo-data protocol extension object should be loaded for the OdDbGeoMapPE module to work.

For all features that require a Bing Maps Key to work properly, make sure that a system variable named CS_MAP_KEY is created and assigned the key value. To learn more about Bing Maps Keys, refer to Getting a Bing Maps Key.

OdDbGeoMapPE module uses third-party libraries:

  • cURL library — Used for getting map images from the Internet (uses BING online service). To access the BING service, set your own BING-map key as a value of the sBingMapsKey global variable.
  • TinyXML library — Used for working with .xml files.
