Hi,

I have problem with importing precise DEM from LIDAR measurements:

Bad property value found.
Object Name: axes
Property Name: ‘XLim’
Values must be increasing and non-NaN.

I’ve tried to produce TIFF file with different coordinate systems (WGS-84, UTM) and vertical datums, and I’ve checked that there are no data gaps or NaN values in Z-coordinate. Anybody had experienced same issue before? Are there any clues or prerequisites to keep in mind while importing user defined DEM?

Thanks you

Matus

DEM visualisation seems alright, however producing Synthetic Amplitude gives empty space

hi Matus,

the DEM you are showing is clearly smaller than the area you are analyzing.
this is not a good situation, since you are analyzing points where the DEM is not defined.
Which DEM value do you want to assign to the points where the DEM is not defined?
Think about it and solve it using an external tool to manipulate your DEM.
Or otherwise select a SAR area contained in your DEM.
