I have the raster file of extracted built-up of my study area.
I wish to divide my study area into grids of 10km.
Total 12 grids.
Can you please tell me how to find the area of builtup features in each grid?
first make up your grid as a vector layer, each having a polygon area with a grid code attribute. If the raster of your built-up area has contineous value, reclassify so that built-up area has one and others have zero value; then convert your raster of the buildup area into a vector layer by `conversion>raster to vector` tool. then use the grid you created to intersect with the built-up vector polygon. you can then merge the area using the gridcode attribute.
You can use the zonal statistic tool in Arc GIS to calculate area by grid
@Gaurav Atreya Thank you do much for the answer. But I have some more doubts. I have made the grid in ArcGis using shapefile of my study area with the tool Data driven pages in Cartography. Also I have the classified image of my study area . I have performed the reclassification on the classified image and 5 land uses were recorded to 1to 5.
1.Can you please tell me how to reclassify buildup as 1 and others as 2?
2.How to divide the study area into different quadrants like NW, SW? SE, SW , N,S,E,W etc?
