Object based classification using ENVI Zoom

This is a small presentation in which I have extracted the impervious surface (rooftops and roads) from a Quickbird image of Colarado. Different steps like segmentation, merging, refining are used to extract the object of interest. The final step of extraction gives its users an option to either use supervised classification method (training data) or do rule based classification. In this presentation I have limited it to supervised classification. I will include the more interesting side of rule based classification in my next presentation. The final step exports the area/ object of interest into a shapefile which in itself has ample applications. I hope its a useful source and motivation for you to explore this feature. Best of luck!!
