Cadastral stereo plotting production from unmmaned aerial vehicles imagery

摘要

Public universities play an important role supporting local governments by providing applied technologies, specially if these cities or towns are located in remote zones, away from large urban centers. This fact involves producing cartography from UAV (RPAS / Drone) used in current photogrammetry can vary in terms of scale within a 1/1000-1/500 range, or even greater, due to aircrafts proximity to ground. These scales imply a transition segment between conventional photogram-metric process and those coming from direct surveying observations, demanding innovative simbolization methods when increased terrain detail levels are gathered during the stereoplot-ting phase. This study presents a 1/1000 stereoplotting work under UAV technology application at a small urban/rural location in south of Chile. The cartographic desired outputs are aimed to generate cadastral plans adding aditional pictoric components with respect to conventional vector representations at mentioned map scales, applying additional pattern recognition algorithms for terrain components.
