Hello there! I'm running Envi 4.8 + IDL. I have RADARSAT-2 data, which I have imported into envi. Now, I want to find the polarimetric signature for a particular location. I input the co-ordinates found using google Earth, into the pixel locator, which provides me the pixel co-ordinates. Then, I select the Polarimetric Signatire tool. I input the HH,HV,VH,VV files, then provide the pixel as the geo-reference point. Till there, it's okay, but when I select the Cartographic System, I can see in IDL that error messages come up, specifically, can't convert STRING to double, and my generation fails. Any help? % Type conversion error: Unable to convert given STRING to Double. % Detected at: SARSCAPE_CARTOGRAPHIC_SYSTEM_GUI_EVENT
