supervised classification dengan erdas imagine 2014

suopnos posted a topic in Indonesian

halo teman-teman gisarea indonesia kebetulan saya sedang mengolah data ALOS PRISM untuk tutupan lahan kota semarang. disini saya menggunakan software Erdas Imagine 2014, saya agak menemui kesulitan dalam prosesnya & semoga diantara teman2 disini bisa membantu memberikan masukan. "apakah tiap kita membuat signature untuk satu nama kelas harus dengan satu area of interest (AOI)? apakah bisa membuat satu kelas dengan banyak AOI? karena dari pengolahan data saya, tiap satu nama kelas harus satu AOI dan hasil supervisednya berantakan." terimakasih

How to extract DEM from ALOS PRISM

suopnos posted a topic in Remote Sensing

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. Thanks
