GIS for Environmental Impact Assessment Training Course

Participants can set up a GIS project with appropriate coordinate systems and map layers.

• Vector, raster and tabular data roles in EIA workflows
• Coordinate reference systems selected for area, distance and reporting accuracy
• Geographic coordinates transformed into suitable projected coordinate reference systems
• Attribute tables structured for receptor records and impact classifications
• Map scale, resolution and positional accuracy matched to decisions
• GIS project folders organised for reproducibility, review and handover

Participants can evaluate and document spatial data quality for EIA use.

• Metadata records capture source, date, scale, licence and limitations
• ISO 19115 metadata elements applied to environmental spatial datasets
• Positional, thematic and temporal accuracy assessed against intended use
• Data lineage documented from acquisition through processing and publication
• Topology rules identify gaps, overlaps and invalid environmental polygons
• Version control procedures protect approved maps and analytical outputs

Participants can select suitable remote-sensing data for baseline and monitoring questions.

• Electromagnetic spectrum bands matched to vegetation, water and built surfaces
• Spatial, spectral, temporal and radiometric resolution compared for EIA
• Landsat and Sentinel missions selected for environmental baseline evidence
• Cloud cover, seasonality and acquisition dates assessed before image selection
• Orthophotos, drone imagery and satellite scenes compared for project needs
• Image preprocessing requirements identified before environmental interpretation

Participants can derive and validate land-cover information from satellite imagery.

• Visual interpretation uses tone, texture, pattern, shape and association
• Supervised classification built from representative training samples
• Normalized Difference Vegetation Index identifies relative vegetation condition
• Land-cover classes aligned with EIA receptors and habitat categories
• Confusion matrices calculate producer, user and overall classification accuracy
