Geoprocessing laboratory activities
Availability of cartographic data and remote sensoriament.
Collection of aerial photos from 1962 to 1972 (both with an approximate scale of 1:25.000) and 1965 (approximate scale 1:60.000) for the entire State of São Paulo. Semi-controlled mosaics at scale 1:100.000 are also available. This material can be accessed at the premises of the laboratory or scanned, by demand of the interested user.
All topographic surveys (1:50.000 and 1:10.000) are open for consultation. The pages of the pedological survey of the State of São Paulo (1:100.000) are open for consultation and are available as digital vector files. The pedological map of the State of São Paulo (1:500.000) is also available in vector file.
Pedological and production environment surveys for the purpose of sugarcane farming.
The activities also include soil mappings for municipalities, hydrographic basins and regions, consisting in field surveys and data analyses through geoprocessing. For enterprises linked with the sugar and energy sector, these mappings and analyses are conducted for determining the production environments for sugarcane, jointly with the IAC Sugarcane Center.
Land use surveys.
Based on the analyses of remote sensoriament data, use mappings and land coverage for areas of interest are carried out. In this process, aerophotography, orthophotography and satellite images of various spatial resolutions are used.
Soil loss modeling.
One of the research lines followed by the laboratory technicians is soil loss modeling through geoprocessing techniques and spatial analysis. The determination of the areas most susceptible to erosion and impacts from the erosion process in hydrographic basins are the main characteristics of these works.
Agroenvironmental diagnosis.
Municipalities and hydrographic basins have been the subject of integrated surveys of the physical environment with an eye towards Agroenvironmental Zoning. This diagnosis allows the different social players (civil society, government and interested parties) to establish more appropriate manners in the use of the natural resources. Multi-criteria analysis techniques associated with the Geographic Information Systems (SIG, in the Portuguese acronym) are currently engaged in these studies.
Courses and training.
The laboratory is equipped to offer courses and training to people interested in using the SIG and also provides for the interpretation of remote sensoriament images.
