Thanks for reaching out. Our processing will give you DEM files that can be used to achieve what you are trying to do. They will likely take some finish work to get them lined up to previously collected data but we have a few customers who do that so it is possible.
We provide some basic tools but the bulk of the data analysis and data handling will still fall on you.
We generally recommend using QGIS but you can use any GIS software for dealing with our output files.
