I have been rasterizing some las files and found something odd. All my geoTiffs have a lot of pixels that are defaulting to min height value - despite me setting options otherwise. Basically it seems that if a GeoTiff pixel doesn't have any Lidar sample points that fall within it, it gets assigned min value?
What I would like is a geoTiff where all pixels have some value, but no matter how I set the options I always get "dead points" in the result.
What is the procedure for making a geotiff where all the height pixels are derived from nearby sample points? I've tried resampling, different sizes and even tried to convert a mesh to Geotiff.. Arg!
