- 7. Retrieving and matching additional boundary data from UKBORDERS
Editor's Notes
- A tabular dataset can be linked to digital boundary data in order to map and analyse data spatially Intersection or overlay of more than one set of spatial units E.g. intersecting points with polygons to identify within which polygon each point lies Number of points or summary of point attributes can be calculated for each polygon Can use to aggregate from one geography to another And to add attributes from multiply polygons to single larger polygon Useful if non-standard geographies or do not have LUT to link
