Compass’ Solution – Geospatial Analysis
Our expert team provided geospatial analysis services to provide insights on a variety of themes impacting the conservation of Atlantic Salmon in the EU.
Using SQL, R programming and ArcGIS, the team merged multiple river networks from estuary to sub-basin level to assess European river connectivity.
An SQL database was developed to consolidate data regarding the existing and historical salmon population using rod catch reports from 2000-2019.
Areas of the network were attributed to identify areas with geographically proximate qualities, ecological quality scores, dendritic connectivity indices and the location of main river barriers.
Water temperature was attributed using previous global monthly levels (1981-2014) and modelled projections for 2020-2080.
These large raster datasets were processed and amalgamated with the appropriate river sections, creating climate change forecasts for individual river networks.
