I've been asked to automate the calculation of cumulative polygon areas within a basins shapefile. The calculation will take the area of the upstream basin and add it to the area of the downstream basin, and continue adding to that cumulative value until reaching the farthest downstream basin. ...
1 I'm trying to export contours from contourf to geojson, the problem is that after generating the polygons, there are actually two lines on top of each other on each border. The question is how to calculate the area of polygons and sort from the largest...

2) The area of a polygon is the amount of space inside the polygon and depends on the units of the objects and their projection (different results) . 3) Therefore, it is easy to calculate the area after using the topological predicate with the command $area in the field calculator ...

17. In the process of reserve calculation using volumetric method, to confirm oil-bearing area is in fact to calculate polygon area. 在用容积法计算地质储量的过程中,含油面积的确定实际上是计算多边形的面积。 18. Step 3: on the base of previous steps and the data prepared, calculate the radiati...
