Hello, good morning, I am working with PIX4D, but I have doubts about how to generate the MDT and perform subproject mergers.
For the generation of the MDT that it has, PIX4D almost always does not do well the selection of the objects that are not proper of the earth, as it is the vegetation, the houses and other things, then that is where the selection has been done manually to identify what things are specific to the earth and what are not. My case is that I am taking the photographs where most of the objects are vegetation, so my question is how high will it take me in those areas when I remove the vegetation (for when they want to make the contour lines) and if it is possible to do a faster selection for objects that are not part of the terrain, since it is very slow when the area is very large.
As for the merging of the subprojects, I saw a PIX4D tutorial where you have to execute process number 1 in each subproject and then merge them and process 2 and 3. My question is if you can perform process 1 and 2 in each subproject and then merge them and do the process 3. (The total area to be built is approximately 46 km2)
I hope you can help me.
