Mapeamento de áreas susceptíveis a sinistros climáticos no município de Rio Claro-SP

This work discourse on Civil Defense’ strategic planning and severe events in the city of Rio Claro – SP. In order to realize spatial analysis about its damages, registered by Civil Defense Department, it is being propose a methodological procedure by the use of Geographical Information System – Arc Gis 9.3.1. and another with SPRING 5.1.8.. The mapping of target areas and their impacts, during a period, have a great importance to the identification of possible risk areas as well as their use for logistic support to corps which is somehow involved to severe events and their victims, and to create a robust alert system

Zoneamento geoambiental como instrumento de planejamento e gestão de recursos do pólo cerâmico de Santa Gertrudes

The disorded and unnplaned occupation is not recent in out territory but it concerns to a historical territorial invasion that roots the time of our country discovery. However, they have started to cause issues nowadays, as in the case of urban conurbations. Somehow these unorganized urban, industrial and agricultural occupations did not have any sort of information or indication of the appropriate situation at that time. Because of that there has been researches by several groups to induce the users of the several renewable and non renewable resources to explore them according to their natural potential capacity.The Ceramic Pole of Santa Gertrudes, the national largest producer of ceramic tile, faces this problem of disorder occupation. Among other themes, the reorganization of the physical environment, proposed by several groups of researchers and scholars of this subject, is gaining attention now.The method of Geoenvironmental Zoning results in a way of prevention from this issue. Crossing information of the physical environment and generating maps whose areas and subdivisions have similar characteristics, it is possible to manage studies and handle these areas according to their potentiality.

Optimization of the sampling scheme for maps of physical and chemical properties estimated by kriging

The sampling scheme is essential in the investigation of the spatial variability of soil properties in Soil Science studies. The high costs of sampling schemes optimized with additional sampling points for each physical and chemical soil property, prevent their use in precision agriculture. The purpose of this study was to obtain an optimal sampling scheme for physical and chemical property sets and investigate its effect on the quality of soil sampling. Soil was sampled on a 42-ha area, with 206 geo-referenced points arranged in a regular grid spaced 50 m from each other, in a depth range of 0.00-0.20 m. In order to obtain an optimal sampling scheme for every physical and chemical property, a sample grid, a medium-scale variogram and the extended Spatial Simulated Annealing (SSA) method were used to minimize kriging variance. The optimization procedure was validated by constructing maps of relative improvement comparing the sample configuration before and after the process. A greater concentration of recommended points in specific areas (NW-SE direction) was observed, which also reflects a greater estimate variance at these locations. The addition of optimal samples, for specific regions, increased the accuracy up to 2 % for chemical and 1 % for physical properties. The use of a sample grid and medium-scale variogram, as previous information for the conception of additional sampling schemes, was very promising to determine the locations of these additional points for all physical and chemical soil properties, enhancing the accuracy of kriging estimates of the physical-chemical properties.
