Hi James
Thanks for the reply.
We are currently using QML for making GUI. But this requirement of extracting heights is not related to GUI. The heights are needed for further calculations. This requirement is pertaining to backend processing. The application shall receive a series of coordinates and GUI has to respond with their corresponding heights. Further GUI shall also tell if these coordinates are present in a particular area (which is present on a vector layer).
That's why I asked if we can access the height information and layer information in a thread.
If there is any sample that extracts the height and accesses the map layer without any intervention of GUI in a thread, please share and please tell the way to do it.
