I am trying to isolate the vegetative cover from the NDVI image which extracted using Landsat TM image . So, could you please let me know how I can do it in Erdas. In ER Mapper I have to write the following formula to perform the vegetative cover separation:
If input1>0 then input1 else null
So, could you please tell me what is the syntax and how to write that formula in Erdas, and then how I can export the isolated vegetative cover to ArcGIS with its float values.
Thanks a lot.
