I have downloaded MODIS MOD10A2 8 day snow cover image. I need to subset this image. I tried to subset the image in erdas. it says the AOI layer is empty.
I think its displaying as empty because you haven't selected the AOI layer after creation. Here are the steps below.
1.Add vector layer to your viewer. Keep in mind the Erdas shows available layers in the native .img format, so you'll need to select the appropriate file type (.shp in my example).
- Once the vector is displayed. Click on it. The selected vector will turn yellow to show you have selected it.
- Once selected, click on the home tab and navigate and click on to Paste From Selected Object. This creates the AOI layer you can use to subset your raster.
4 Click somewhere in the middle of the polygon and bounding characteristics will be shown. Be careful, though since you can accidentally move or alter your AOI's geometry.
