QUANTIFIYING URBAN TREE CANOPY USING GIS
This Wales-wide project was assigned to GSD by Natural Resources Wales (NRW) and looked to update the data held on Wales’ Urban Tree Canopy Cover by comparing data with updated aerial imagery. From specifications set by the client, processes were created for a consistent approach to the analysis and quality assurance of the data created across a team of five analysts. Our technical lead kept in regular contact with the rest of the team, monitoring progress and regularly reporting on progress with our client.
The data were processed using a custom GSD python script and open-source GIS tools. Quality assurance and consistency checks were carried out regularly by the technical lead using a range of different approaches developed at the start of the project; these evolved as the project developed and in response to the clients' needs. At the end of the project, GSD summarised the results of the project and recommendations for future processes in a final report that is now available from NRW and is in the public domain..
