Generating off-grid clusters
Using the OSM data as a primary datasource, off-grid clusters are then calculated for areas greater than 5 km from the medium voltage grid. These are displayed on the
SE4ALL webmap as “remotely mapped settlements”. The building data from OSM is buffered outwards, merged and buffered inwards again. Key statistics are calculated on each of the remotely mapped settlements including:
- Area in km² of the remotely mapped settlement
- A count of the number of buildings within the cluster
- The total combined area of building footprints, divided by the total area which results in a “built-up ratio”
All of these criteria can be filtered on, to provide you with a custom filter of clusters.
