This week was a fun introduction into ERDAS Imagine and illustrating what it can do. We saw the difference in what AVHRR and TM files can show us. Also with the TM photos, we were able to manipulate the vision spectrum to help identify different land features.
After working through some of Imagine's features, we created a subset of a TM map and used that within ArcGIS to develop a map which showed how much area in hectares of each land type feature that were highlighted on the map. One issues I was not able to overcome was reordering the legend on the map. Personally I would have preferred sorting the legend by most to least hectares. Definitely a challenge I will need to figure out down the road. The picture below shows my map from ArcGIS.
