GIS Services

Geographic Information System (GIS) Services

Impact GIS has 20 years’ experience using GIS for data acquisition, data analysis, and visualisation. Services include:

  • Data creation / acquisition;
  • Data conversion / manipulation;
  • Data analysis & reporting; and
  • Visualizations, including the production of maps, figures and atlases.

With most state bodies distributing spatial data in GIS formats, GIS is now integral to Strategic Environmental Assessment (SEA), Environmental Impact Assessment (EIA), Cultural Heritage Assessment (CHA), Appropriate Assessment (AA), planning and development, and more.

Usage cases:

Strategic Environmental Assessment (SEA) – using spatial analysis and weighted overlays to visualise area of environmental sensitivity, as outlined in the EPA’s GISEA Manual.

Appropriate Assessment (AA) – Analysing which Natura sites (Special Areas of Conservation (SAC) or Special Protection Areas (SPA)) are located in the vicinity of a proposed development and how far away they are from the proposed development boundary for an Appropriate Assessment Screening report.

Constraints Analysis – for large scale infrastructure projects the use of robust constraints mapping, spatial analysis and weighted overlays is a powerful tool to drive the selection of study areas and preliminary route corridors.
