This page describes how to set up a project to calculate the lot- or floor-size of a set of buildings within a distance of a waterway. See section [Variations] for other examples and inspirations how to model your distance calculations for your own use cases.
Introduction
Let us consider the following use-case. As an authority, I am interested in how to calculate the amount of water-edge friendly vegetation, within 20 meters of the water edge. Using TQL, it is already easy to calculate the amount of square meters of a specific function or category, but how to restrict counting the vegetatino within 20 meters of the water edge?
