So what I have is a dataset of mines (coal, bauxite, iron ore etc) in Central India and their lat, long. I also have the values for actual area of each of these mines, as per Environmental clearance documents.
I initially tried looking at Google earth satellite imagery to digitize polygons showing the actual extent of each of these mines. However not all of these mines have begun operations. So satellite imagery does not tell me how big these mines will eventually be and I ended up just making a point layer for the mines
I was hoping to prepare a web map (in cartodb) and one in qgis that allows me to style the point layer according to real area of the mine. Hence if the area of the mine is 100 hectares the point should show as a circle of area 100 hectares and accordingly adjust at different zoom levels. Is there an easy way to do this? one which doesn't involve a lot of code.
Thanks!
