Hi
I need to display the raster map, before this i don’t have any issue to rendered the map. Unfortunately, this error occurs when i try to click on map many times it will throws this error:
Exception Unhandled
with message
System.ArgumentOutOfRangeException: ‘The input double value is out of range.’
What the issues of this? I thought it because of my Gdal code that i use to display elevation data, but after i try without the Gdal code it throws the same error.
