Geometrical calculations on vector layers

In previous sections, we covered the querying of the immediately available properties of vector layers (for example, the CRS definition or attribute table), and the modification of vector layers involving only the attribute table component (for example, removing the attribute table or subsetting the layer according to it). In the next two sections, you will learn to examine and modify the geometrical component of vector layers. In this section, operations involving a single vector layer, such as reprojection and area calculation, will be covered. In the next section, we will deal with operations involving pairs of vector layers.

Reprojecting vector layers

Reprojection is the conversion of all the coordinates ...
