Conteúdo: | Some areas in Brazil are being studied to define wine terroirs and improve the quality of wines. The Brazilian Agricultural Research Corporation (Embrapa Grape and Wine) currently uses satellite images and geographic information system (GIS) for studies of geographical appellation for fine wines. Aerial surveys initially used to restore the maps were very expensive and tested alternative in this work to reduce costs were ALOS (Advanced Land Observation Satellite) image to generate digital elevation model (DEM) and to orthorectificate high resolution image ? such as IKONOS for land use survey and vineyards. Recently in the Serra Gaúcha Wine Region, a study for the geographical appellation of Altos Montes is being developed with partnership of the producers. The ground control points (GCP) was obtained by precision global position system (GPS), a Rational Polynomial Camera (RPC) model was built to obtain the stereoscopic image pair PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping) and IKONOS. Although ALOS be out of service since April 2011, the PRISM system is still useful for researching the relief features. So it was possible to characterize the area of geographical appellation by multiple criteria such as altitude, slope, exposure, land use and it was still possible to register the vineyards of producers in GIS and its attributes. Planimetric maps, image-maps and land use maps were produced for a detailed scale (1: 5000).
