article covering large areas in short time a high resolution orthomosaic in brazil a high resolution orthomosaic was generated for the 800 km2 area of the county of campinas, brazil, derived from ikonos satellite imagery, a digital terrain model (dtm) generated from worldview-1 satellite imagery, and an implemented geodetic network of 19 points. the final orthomosaic was generated both in normal color and in false color infrared in order to broaden the possible applications to environmental issues. this result represents a very interesting solution to cover large areas in short time and with a lower cost than traditional aerophotogrammetric methods, thus with basically the same quality, allowing for a better assertive planning and sustainable development of the territory. by nelson de jesus parada, ulfh walter palme, jason san souci and philip cheng figure 1 vrt-29 on ikonos imagery. 1. introduction in brazil, outdated territorial and cartographic data are unfortunately still very common and the planning activities in a fast-paced urban expansion environment represent a rough challenge to urban planners and managers, especially in day-to-day activities. this is also the case for the county of campinas, where in recent years the population growth has surpassed 1 million inhabitants and is still growing. also, the metropolitan area of campinas, including 19 other counties, is under great pressure. these boundary conditions make updated cartography and territorial monitoring a constant necessity, because of aggressive planning and management schedules. in order to deliver to sanasa the water supply and sanitation company of the county of campinas - and to the gis county of campinas administration project, an updated cartography and technical cooperation agreement was signed between sanasa and funcate to generate a new orthomosaic of the county of campinas derived from high resjuly/august 2009 22
