Resumo:  In the ?Metade Sul? region, Rio Grande do Sul, Brazil, some vineyard appeared and studies approaching geographic indication using geotechnology have been developed by Embrapa Grape and Wine, such as Serra Gaúcha and others places. The object of this work is to test digital elevation models (MDE) from ASTER and SRTM data, with different resolutions, to generate elements to characterize the natural factors in Serra do Sudeste, Encruzilhada do Sul, situated in the center of Rio Grande do Sul State, Brazil. This work supports studies of winery terroir, that relates to natural characteristics of farm, such as soil, rock, landscape and climate, that determine specificity to wines produced to each place. Orbital images have been used to identify terroirs to generate landscape models, by digital image processing (DIP) and integrate thematic maps to generate terroir potential units. For the moment, this study approaches terroir from landscape and its data and their products were crossed into geographic information system (GIS) environment from low (SRTM) and medium resolution (ASTER) to supports choice of orbital source for agricultural zoning, in order to establish potential criteria to identify terroirs in this region. The MDEs generated elevation, declivity and aspect maps, also derived data to applied in wine management and after, were integrated and reclassified. The analysis of all information in the SIG led to compare different orbital data with different resolution and how much these attributes (altimetry, declivity and aspect) can support grape vine development.
