Processing steps

To compute the whole indicators and classifications, GeoClimate chains a set of spatial analysis and statistical processes organized in 3 steps (Figure 1). It's important to note that all those processes can be run individually.

1. Building new spatial units

The first step of the GeoClimate chain concerns the construction of two new spatial units (block and RSU).

  • a block defined as an aggregation of buildings that are in contact,
  • a RSU (Reference Spatial Unit) is a continuous and homogeneous way to divide the space using topographic constraints sent as input data : road, railway, vegetation, water. The construction of RSUs is a major step in GeoClimate. This method consists in building a planar graph with all input geometries. The planar graph is then traversed to create new polygons.
