I want to identify new houses built from 2015 to 2016 using satellite imagery (MSI and SAR)
Would anyone have any suggestions how to go about this?
I was thinking if I did a supervised pixel classification of both images (2015 and 2016) and used classes such as vegetation. soil, water, forestry, built up to create 2 landcover classifications. If i think converted these raster classifications to vector data sets, and exported only the ‘built up’ polygon from 2015 and 2016, and then clipped the old 2015 ‘built up’ vector set, to the new 2016 ‘built up’ vector set, the ‘new built up areas’ would be left over.
Would this approach be correct in theory?
