suopnos Posted October 21, 2015 Report Share Posted October 21, 2015 Hello,I'm trying to create DEM from PRISM image, I try to use ENVI but I do not know how it works.as far I know, DEM can be extracted from PRISM by min two pairs of image (nadir & backward, nadir & forward, etc.). How do we know type of PRISM whether its nadir image or backward image? is anyone have tried to create DEM from PRISM? I appreciate all of you who can help.

pasfans01 Posted October 21, 2015 Report Share Posted October 21, 2015 You can look into the metadata, (LED or TRL file, I dont quite remember) if you wanna know the acquisition mode, | and the other way, you can look in its file/folder name, it is mention the acquisition mode in the filename, ENVI is only support Level 1B1, 1B2R and 1B2G of ALOS PRISM, if your data is level 1A, I suggest you to use ERDAS IMAGINE which it is fully support ALOS PRISM, include the DEM extraction 2 Quote Link to comment Share on other sites More sharing options...
