This will be a short explanation because I have been burning the candle from both ends for several days and I'll soon crash.
So this week I preformed a supervised classification of land use for Germantown, Maryland using Erdas and its supervised tool.
An AOI image was added to the provided aerial image, and using a mix of the Inquire (legacy) cursor, region growing properties tool, signature editor, offered coordinates and classifications, a heavy dose of eyeballing and referring to examples classified the land use. Then I recoded the classes to be a single number, re-added the names of the classes that correspond to the number, and add area.
It sounds easy but between being so tired and being slightly unsure if I was doing things right I re-did and deleted things several times until I was satisfied. Which only took 7 hours just for the last exercise before I transferred the image to Arc GIS Pro and created the map which is below.
