Identification of most suitable area for crushed stone aggregates using GIS method: a case study in Koprivnica Križevci county, Croatia

Aggregate is a low unit-value mineral commodity. Transport costs for aggregate from the mine site to the point of use is a large fraction of the resource cost to users. Production sites for aggregate occur where suitable source materials exist and where transportation and market conditions are favourable. The increasing demand for aggregate and the difficulty of developing and permitting new sites and of renewal of permits on existing sites of aggregate production indicates that aggregate will be supplied from sources yet to be developed or delineated in many areas. The purpose of this paper is to assess the crushed rock aggregate resources in the Koprivnica Križevci County and to delineate areas with aggregate resources. The suitable site selection is performed using the geographical information system (GIS) approach with weighted overlay analysis. In the Koprivnica Križevci County gravel and sands and crushed stone aggregates are quarrying from around 30 exploitation sites (KRUK et al., 2015). Map correlation and map-integration processes were 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 stone quarries or gravel and sand pits (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 county and production information. The spatial correlation between all thematic data allowed us to prepare the final suitability map (Fig.1.). Based on the results of this paper, various aggregate potential areas in the Koprivnica Križevci County have been selected and each one has been assigned to categorie (suitable, moderately suitable and unsuitable) representing their suitability levels for future development in terms of the environmental constraints, availability of transport networks, current land use, and availability of mineral reserves. This analysis and classification provide important information for policy makers to decide on effective land and resource management plan, and for regional or state authorities in the process of granting licenses to operate a stone quarries or sand and gravel pits.
