Application of ArcSDM extension favorability modelling of stone aggregate in Dalmatia ; Croatia

In the four Dalmatian counties aggregates and natural stone is quarried at 155 sites and 73 abandoned sites. Map correlation and map- integration processes was made using ArcSDM extension tool (Weights of evidence) to define relationships between spatial layers and combine predictor factors in supporting a hypothesis. The response variable is the set of point locations of current aggregate and natural stone quarries (termed training sites), and the predictor variables which are thematic map layers showing transportation network patterns, population density distribution, maps of geological mineral potential, and areas of mineral exploitation restrictions defined by Master plans of the counties and production information. Based on the GIS model, stone aggregate potential is calculated to cover more than 15% Dalmatian land area. The GIS model allows resource management and prioritisation of potential mineral extraction tracts (and sites) in Dalmatia while taking in account both environmental restictions and marketplace needs.
