AbstractUnderstanding spatial variation of rock and soil is important for capability precision as well as groundwater contamination or geopollution management. In view of waste dump/landfills, geoenvironmental hazards ravaging our land including surface and groundwater contamination, site suitability indexing, spatial distribution and characteristics of underlying rock and soil matter are studied. Rock and soil samples were collected in a systematic grid pattern using simple drill core rig and hand auger. Geostatistical and soil property analyses were conducted on each grid. Groundwater aquifer vulnerability to leachate was studied using depth to water table, recharge (precipitation), aquifer material, topographic slope, impact on vadose zone/vadose zone material and hydraulic conductivity (DRASTIC) and geophysical methods. Human population growth analysis indicates tremendous waste generation. Flash points of waste generation and dumping were noted. Geographical positioning system was used to take record of sampling point coordinates. Using a sufficient dataset, each grid indicative factor is objectively scaled, weighed and assigned a numerical rating according to their relative importance employing site suitability (S) analysis approach in an empirical equation. Results were imported into a geographic information system (GIS) platform to generate thematic maps. The results showed that subsurface rock and soil characteristics are neither spatially nor vertically homogeneously distributed. Thematic maps were generated and further interpolated in the GIS domain to produce a composite waste dump/landfill suitability index map.

Through the analysis of land use actuality, this paper summarizes the characteristics of land use, in virtue of geographic information system (GIS) platform, the database of land consolidation is constructed, combining with different calculation models of cultivated land and rural residential land consolidation potential, the consolidation potentials of cultivated land and rural residential land are calculated, and the thematic maps about land consolidation potential of each village and town in study area are mapped out. The results show that the land consolidation areas are mainly concentrated in the middle of study area.

A mountain area in Southeastern Greece exposed to wildland fire problems was used to establish a method for fire danger zoning. Meteorological risk (MR), fuel susceptibility (FS) and fire occurrence (FO) maps are created. The method integrates these maps and produces the constant and variable danger (CFD,VFD) zones that require respective activities for wildland fire prevention. A Geographic Information System (GIS) was used to perform the overlay analysis of thematic maps and delineate the fire danger zones.

Abstract: Geographic Information System of Diarrhea in Children in the Area of Puskemas Kota Banjarbaru. Incidence of diarrhea was always found every year in Banjarbaru. Incidence rate of diarrhea in Banjarbaru in 2009 to 2012 are respectively 20.98, 19.86, and 16.39. The presentation of data on the incidence of diarrhea mainly done using tables and graphs. The aim of the study was to describe the incidence of diarrhea in children aged less than 5 years in the area of Puskemas Kota Banjarbaru using geographic information system. This research is a descriptive study. Four of the eight health centers in Banjarbaru was chosen as samples. All children aged less than 5 years old who suffered from diarrhea in the four regions had been recorded. Furthermore, measurements of the coordinates of the house where there is a child aged less than 5 years of the living was done. Based on data from the coordinates, thematic maps of the incidence of diarrhea was made. The results showed that during the months of January to June 2013, the incidence of diarrhea is solid in the areas of Puskesmas Banjarbaru and Puskesmas Sungai Besar, is width in the Puskesmas Sungai Ulin, and is solid and long in the area of Puskesmas Cempaka. The results showed that during the months of January to June 2013, the incidence of diarrhea is solid in the areas of Puskesmas Banjarbaru and Puskesmas Sungai Besar, is width in the Puskesmas Sungai Ulin, and is solid and long in the area of Puskesmas Cempaka. It is recommended that a follow-up is done in order to prevent or reduce the incidence of diarrhea through concrete and effective interventions.Keywords  :   Diarrhea; GIS; Banjarbaru
