Combined Geospatial Approch to Extract Spatial Data from UAV Imageries

Abstract

Evaluation of UAV have opened the whole new world of survey with less cost. Vertical and Oblique aerial imageries took from UAV's are used to generate various geospatial data like high resolution ortho photo, color point clouds, DSM, DTM and 3D models [1]. The main objectives of this paper is to understand the UAV systems, components, image acquisition technique and high precision geo data extraction method from UAV imageries for better spatial decision support system [2] .
