I am new to GIS and also QGIS tool.
There are two layers imported into the qgis project. Layer-1 (green) has attributes ID, area, code Layer-2 (brown) has attributes station, shp_area, name.
I want to divide the polygons by overlapping and then add a new field value with the divided polygon's respective area. Other fields will remain the same of Layer-1 For e.g. Along the border of one polygon (brown border), a larger polygon (green) was divided into two polygons. The total area before division was 125sqm. After division (shown in red), the areas respectively became 70sqm and 55sqm.
I want to do this in the entire shapefile and store the new output (divided green areas) as Red-layer.
