QGIS

By audience

Civil Engineering

• Civil engineers build site and corridor constraint maps from terrain, flood, utility and land-ownership layers before design starts.
• Engineers run slope, catchment and flow-path analysis on digital elevation models from the Processing toolbox.

Environmental Engineering

• Environmental engineers map habitats, flood zones and contamination data to support permitting and environmental assessments.
• Processing models turn a screening workflow into a repeatable process that is re-run when source data is updated.

Landscape Architecture

• Landscape architects map existing trees, vegetation, terrain and drainage to prepare site analysis drawings.
• Tree and green-space inventories captured in the field are edited and mapped in QGIS for planting and site proposals.

Planning

• Planners overlay zoning, land-use and constraint layers to screen candidate sites and prepare master-plan mapping.
• The print layout and atlas tools produce consistent large-format maps for planning applications and consultations.

Surveying/Geomatics

• Surveyors import survey points and scans, reproject them between coordinate reference systems and digitise features with the CAD-like advanced digitising tools.
• Geomatics teams publish cleaned survey and base-map layers to the wider project team as OGC WMS and WFS services through QGIS Server.

By phase

Concept & Planning

• Teams compare candidate sites by overlaying terrain, flood risk, ownership and planning-constraint layers.
• Feasibility and entitlement maps are produced with the print layout designer for clients and planning authorities.

Design

• Survey, base-map and environmental layers are prepared in the project coordinate reference system and exported, for example to DXF, for CAD and BIM teams.
• Designers test options against terrain, visibility and drainage analysis run in the Processing toolbox.
