Lake water quality is affected by local and regional drivers, including lake physical characteristics, hydrology, landscape position, land cover, land use, geology, and climate. Here, we demonstrate the utility of hypothesis testing within the landscape limnology framework using a random forest algorithm on a national-scale, spatially explicit data set, the United States Environmental Protectio...
The Mineral Potential Project is an initiative that provides predictions of resource abundance in the province and has been described by Kilby (1995). Ian this project, resource assessment is carried out on specified tracts of land, referred to as mineral assessment tracts. These tracts are generalizations of contiguous geological tracts that share a common tectonic history and metallogeny and ...

This study applies a Back-Propagation Neural Network to the task of floristic land cover classification. The input data consists of the three LANDSAT TM bands 2, 4 and 7 and the GIS based environmental variables Aspect, Elevation, Catchment, Geology and Slope. This dataset covers a 225 square-km sub scene centred near the town of Kioloa, South East, Australia. The study area is complex compnsmg...
This study looks at the application of GIS clustering approaches to airborne radiometric and electromagnetic point sampled data in an attempt to predict known geology in the UK at a small scale of part of the Derbyshire Dome area, and at a large scale of part of the Trent Valley. Spatially autocorrelated deviations in the automatic classification from the mapped geology were investigated furthe...

The observation of peak flows into river or stream system is not straight forward but complex function of hydrology and geology. Accurate suspended sediment prediction in rivers is an integral component of sustainable water resources and environmental systems modeling. Agricultural fields’ fertility decays, rivers capacity decreases and reservoirs are filled due to sedimentation. The observatio...
