GeoSpatial Modelling
Terranean Mapping Technologies prides itself on its ability to find practical and innovative ways to apply spatial technologies to produce maps and derive information, which historically has been difficult to obtain.
GeoSpatial modelling includes both predictive models and mechanistic models. Statistical models apply multi-variate and other statistical techniques to predict the distributions of variables based on measured correlations. Mechanistic models simulate processes that occur within the landscape.
A number of GeoSpatial Modelling projects completed by Terranean are described here.
Scenic amenity modeling
In an increasingly urbanised and environmentally conscious Australia,
organisations are tying to place development where it least impacts the
community’s high-priority landscapes. Terranean won two prestigious
Planning Institute of Australia Awards for its work in modelling Scenic
Amenity for the Caboolture Shire Council.
Ecological modelling to predict plant communities
Terranean’s work in ecological modelling, based on variables such
as topographic exposure, slope, aspect, catchment area, steepness, and
geology, predicts the distribution of plant species and communities,
and has been widely recognised and used.
Geological Modelling
By integrating information such as satellite images, digital topography, geophysical, geopchemical data and DEMs, we refined mineralisation models to better understand the sub surface geology of the Gympie Gold Field .
This model provided the basis for intensive drilling programs and major investments in the expansion of the mine, including the construction of a “drive-in” decline.
Flood Modeling
By integrating DEM data with other spatial data including the road network, Terranean employed Terrain Modelling techniques to forecast the likely impact of different flood scenarios in the vulnerable canal estates of Gold Coast City.
Tree Counting
Australian tree plantations are becoming the preferred source of timber, instead of imported timer and native forest logging. An essential management tool, used to achieve maximum productivity, is the replacement of dead trees by live, productive trees.
Terranean has used infrared photography to largely replace the need for on-ground surveys to establish where dead trees are located.
This infra-red areal photograph was analysed using software developed by Terranean, to count the number of tree seedlings that had survived or died after one year.
