lascanopy64.exe produces the error "ERROR: cannot determine the writer for format 'tif'" or ERROR: cannot determine the writer for format 'img" if I try and output tif and img.

Any obvious reason for this error?

I can only output in .asc format successfully.

Hello,

As indicated in the CHANGES.txt file, the new 64 bit executables that generate rasters (lasgrid64, las2dem64, and lascanopy64) can only output rasters in ASC, BIL, XYZ, DTM, and LAZ format for the time being.

Regards,

Martin @rapidlasso

Any timeline for when TIFF output will be introduced? It would be immensely helpful to our workflow. The other formats are OK but they are a bit dated. Thanks!

No timeline yet.

Have you tried LAZ as your intermediate raster format? It's an incredible compact way to store a DTM. From LAZ you can go to any other image format by lasgridding with the right '-step 0.5' size. And it still loads into any LiDAR processing software that has LAZ support. Here an example:

Creating the same raster in LAZ, TIF, IMG, BIL, ASC, and XYZ format:

C:\LAStools\bin>las2dem -i ..\data\zurich.laz -step 0.2 -spike_free 0.6 -o zurich_dsm20cm.laz
