Hi, I have ever got a remote sensing image from the web, and the projection info, geographic extent of the image was infomed by the website. While, when I add this image to ArcMap, the extent info of the image was incorrect. The top-bottom extent was right, but the west-east extent was negative (It shoule be positive in my case). The extent info is: Top: 181932.421394 Left: -1364517.22021 Right: -1273549.15876 Bottom: 90964.3599472 So, I am wondering how to change the extent info of my image file? I have ever tried in the "Layer Properties" windows, ->Extent->Set Set the extent to: a custom extent entered below. But after I make changes, and press “OK”. When I reopen the properties of the raster file, the extent info is still the original, thus wrong. Can any has some idea how to handle my case? Thanks, Leo
