Hello all, I have PALSAR images, level 4.1 product with slant range projection. I converted from slant to ground range projection in ENVI using information from published document. The steps in ENVI are: a. Radar---> slant to range ----> generic ( I did not find PALSAR in ENVI 4.5 and 4.6) b. I put instrument height : 695.65 km ( I got it from published document) c. Near range distance from publsihed document is 31.6 degree, however, this is for FBS (single  not dual polarization) and for level 1.1 and 1.5 product d. Slant range pixel size (from the ENVI help this pixel size is not from the input image), then what is it? e. Near range location: left. My questions are: 1. What is the input data actually for slant range pixel size? 2. What are the documents that give the required information ?, 3. Is this conversion procedure the same for level 1.1 , 1.5 and 4.1 products? Thanks in advance for your reply, Tyas
