OSGEO4W

OSGeo4W download: You will probably have to use Edge or Firefox, and override the browser's overly conservative attitude. If at all possible do this from the ethernet, and not Wifi. You will wind up with a 1.6 GB directory, and the installation takes some time. If the installation has problems in the middle, the intallation will be corrupt and you will probably have to manually delete the c:\osgeo4w folder and download again.

Once you have installed the package, MICRODEM will find it and will perform all the GDAL operations. You might have to restart MICRODEM if it was open during the install so that it will find GDAL.

Detailed directions for Edge download:

To "cannot be downloaded securely" pick "See More"
On the line for the osgeo42 download, pick the "..." and then Keep
Pick "Keep anyway"
Pick "Open File"
Pick Express Install
Pick any of the available servers
Pick all four packages
Next to accept the unmet dependencies
Accept multiple licence terms
Sit back and wait (might be as little as 6 minutes on the ethnernet with little network congestion_
The percentage in the window caption and the status bars will restart several times, so don't get your hopes up

Sofware included, with some options directly from MICRODEM

SAGA. Can be called from QGIS.
GRASS.Can be called from QGIS.
libLAS
PDAL, which requires a custom installation so it will be included.
