Our GIS team routinely uses Esri ArcGIS, the industry standard GIS package, and open source platforms such as QGIS. GRASS GIS, the R analysis environment, and the PostGIS spatial relational database management system are used for more complex queries. The GIS team has also established mapping templates for common outputs (such as Phase 1 habitat survey) to guarantee clear, consistent and well-presented figures.
BSG’s spatial data outputs are validated to the INSPIRE metadata standard and will integrate with the client’s own GIS or CAD systems. Our maps conform to the BS 42020 requirements and undergo a rigorous peer review process.
Baseline Survey and Data Analysis
Examples of typical applications of GIS with regard to the collection and analysis of field data include:
* Thematic mapping: we produce clear habitat and species maps in GIS, complementing field data with aerial photography, remote sensing and topographic mapping for accuracy.
– 3d visualisation, remote sensing and hydrological analysis: used to correlate habitat distribution with other environmental factors (vegetation condition, altitude, gradient, watersheds) ensuring accuracy.
- Desk-based studies: working with protected species records and designated sites data our team can assess potential ecology issues, directing our field survey efforts and informing our recommendations.
- Baseline bat surveys: results of transect surveys are digitally recorded in the field and visualised to indicate areas of bat activity. Preliminary analysis of remote survey data is conducted in GIS to display levels of bat activity over a survey season / across different parts of the development site.
