Dear All! I have one problem, i have a RapidEye Scene in ENVi 5 (Student Version) and i also have map with Ground Truth data (crop fields that are with codes for each crop and land use type). So, now i have to create ROIs from this data on this satellite scene. Just by "create a ROI"- its possible to draw polygone, polyline etc. but the fields on satellite scene are pretty small to distinguish them, as they are on normal topographic map. Can someone help me pleaseee? Thanks!!!! Nadia

How is your ground truth data stored or provided to you? Does it come as vector files? ENVI will convert vectors to ROIs based on the map coordinates so you should not need to draw the vectors if they already come in this format. Then they will overlay in their appropriate map location regardless of how small they are.
