trying to isolate a few classes (records in table) and make an aoi out of them to subset. I can select the classes but cant find where to make AOI out of selection. Its been a while since I have done this. Not use to this GUI interface.
If classes are thematic raster then you must to raster to vector conversion and maybe recode before that to drop out classes you do not want. Same is probably doable from direct raster to vector and only choose certain pixel values. Or is your classification already a vector and you need to select the right ones and do simple copy-paste.
Only way to really generate AOI in Imagine is either manual digitizing or copy past from existing vector.
Maybe I was not clear. I kinda want to do a cluster bust. I have a class that I need to set apart from the other classes and run another ISOcluster on that class to further break it down. In the older imagine I was able to select the row from the table and make and AOI around that selected class then run a ISO using that AOI. Tryig to do same thing here. Im just not use to this version.
You should be able to do exactly the same thing via the Ribbon interface. The link Jeff provides above gives some details, but basically do what you did previously, but use the Paste from Selected Object button (not the regular Paste button - they are adjacent to each other on the Home tab) to create the objects in an AOI layer from the selected class(es). Then use the AOI in the Unsupervised Classification dialog as you would have previously.
I'll see if I can create a quick video to show you the steps.
