GIS Our place in the landscape

Biosis uses current GIS technology and expertise to facilitate decision making in all of our service areas.

Geographical Information Systems (GIS) software allows data collected by Biosis field teams to be analysed, assessed and presented in the context of base datasets acquired from contemporary and historical sources. These sources can be combined and extrapolated to model ‘what if’ scenarios.

Virtually all aspects of ecological and heritage impact assessment and monitoring involve recording or predicting the location of potential constraints in context of proposed development. GIS allows Biosis consultants and clients to easily visualise potential constraints and opportunities and also quantify impacts to ecological and heritage values in a repeatable and scientifically based way.

Spread across our local offices, the Biosis GIS team consists of GIS professionals proficient in the use of both esri ArcGIS and MapInfo software. The members of our GIS team work closely together to share local knowledge of available data sources and associated issues as well as maintaining a consistent, best practice approach to spatial data management and analysis.

GIS and Ecology

As well as presenting base maps and GPS data collected by Biosis consultants in the field, the Biosis GIS team also provides a number of specialist services that support the delivery of ecology services to our clients.

These specialist services include:

  • calculation of stream catchments and flow accumulation data from modeled terrain data,
  • quantifying impacts of proposed development footprints on native vegetation and fauna habitat,
  • weighted overlay analysis to identify and rank criteria desirable for locating offset land.

Biosis has recently created geoprocessing models to quickly and automatically identify potential upland swamps in large tracts of difficult to access land using Light Detection and Ranging (LiDAR) data and spatial analysis techniques.

GIS and Heritage

The Biosis GIS team maps current results from government databases to represent recorded areas of Aboriginal and European Cultural sensitivity in a way that is visually clear and easy to interpret. Spatial querying tools are used to efficiently produce lists of registered heritage items and places directly or indirectly affected by proposed development footprints.

Map automation tools and techniques are also used to vastly reduce the time taken to produce site card figures required by government bodies when registering a newly discovered Aboriginal cultural place.

Biosis uses automated GIS models to classify elements of the natural topography in terms of their likelihood to contain Aboriginal places. These elements are then combined into a weighted overlay to create representations of archaeological potential across a large area based on current best practice predictive modeling in Aboriginal archaeology.
