Hi,
I have some questions, I appreciate that if someone could answer.
As I Know lidar technology can not catch points in channels (under water) and normally in engineering firms, they get survey for channels and use lidar for the floodplain, and incorporate them together into a DEM.
My questions are:
1-In which format the survey data should be? (x,y,z format or station elevation format)
2-Is it possible to make geometry from several channel cross section in Arcmap? (Like Hecras)
3-How can I incorporate survey data(channel) and Lidar data(Floodplain) together in Arcmap and make a dem?
cheers.
