topic Display 2D map but consider heights in calculations in Qt Maps SDK Questions https://community.esri.com/t5/qt-maps-sdk-questions/display-2d-map-but-consider-heights-in/m-p/269582#M1371 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P></P><P>I'm using qml display with c++ logic. I have a 2D map display with MapQuickView which loads a raster map from a tiff file and it works well.

I wonder if you could create a Geoprocessing Service or Package in Desktop and consume that in Runtime with a GeoprocessingTask?
