Abstract

CALDERANO FILHO, Braz et al. Geoenvironmental study of municipality of Bom Jardim - RJ, with support of geographical information system: subsidies to planning of mountainous rural landscapes. Soc. nat. (Online) [online]. 2010, vol.22, n.1, pp.55-73. ISSN 1982-4513.  https://doi.org/10.1590/S1982-45132010000100005.

This research aims to produce biophysical information of the landscape components, with the objective to supply a background to the environmental planning of the rural areas in the mountainous region of Serra dos Orgaos, under family agriculture. With support of geographical information system, this research has combined digital mapping techniques based on remote sensing with digital elevation model (DEM), aiming to optimize the field thematic maps and to facilitate the generation of maps and useful interpretations, in order to use them for planning purposes. The procedures used in this research took into consideration the creation of a database based on digital data from the GIS, and the generation of basic data obtained in the field, through environmental thematic maps associated with socio-economic information, rainfall data and protected areas, based on legislation, creating therefore, a set of agro-socio-environmental information in a digital system. The results allow us to discriminate and to characterize the physical and ecological landscape elements, contributing to a better understanding of the environmental resources and their potentialities and limitations, besides to contribute to the environmental planning and to create a conservationist managing plan to the research area.

Keywords : Environmental assessment; Digital elevation model; Geoprocessing; Soil and water management.
