Dear Researchers, I am doing LULC classification using Decision Tree (threshold method) to analyze the urban sprawl and LULC-LST. There are a lot of uncultivated land in the imagery (I checked with Google Earth images) with low NDVI values & reddish grey color in FCC. I am going with 4 classes: Water, Built-up, Vegetation & Open land (can also be termed as "Others"). Should i group the uncultivated land with Vegetation or Open land?
That land shows Uncultivated for more then three years you group with open land because most of the vegetation lands are session based so check the land profile minimum three years in google itself.
this might help you

furthermore, you have to check are these lands permanently uncultivated or uncultivated for the time being, I will recommend you to follow IPCC Guidelines 2006 for this purpose.
Selvasekar Thirumurthy Thanks for the answer. Yes those uncultivated lands are season based and the image acquisition day is just after the harvesting period, hence i have classified it into vegetation.
