I downloaded some LIDAR elevation files from the following page:
Unfortunately they are full of voids I'd like to fill. First step was to take a low resolution map around the DEM and feather the edges of the high resolution LIDAR in Global Mapper. After that the LIDAR file merged in more or less but there are still many voids within the area I don't know how to get rid of in Global Mapper (see attached file showing the source).
There seem to be many tools around that can fill voids by interpolation what would be very good for my needs but all tools I could find can only read SRTM HGT files. This raises the question:
If there is no way to interpolate those voids in Global Mapper: Is there any possibility to export high resolution LIDAR data to a HGT file that can be read by those tools?:
