DIGITAL ELEVATION MODEL FROM NON-METRIC CAMERA IN UAS COMPARED WITH LIDAR TECHNOLOGY

摘要: Abstract. Digital Elevation Model (DEM) data as a representation of surface topography is highly demanded for use in spatial analysis and modelling. Aimed to that issue many methods acquisition process it are developed, from traditional surveying until modern technology like LIDAR. On the other hands, past four year development Unamend Aerial System (UAS) aimed Geomatic bring us possibility acquire about by non-metric digital camera on board short time with good quality some analysis. Data collectors have attracted tremendous attention UAS due determination volume changes over time, monitoring breakwaters, hydrological modelling including flood simulation, drainage networks, among others whose support DEM proper The considered combination accuracy suitability so; this paper analyse compared LIDAR corresponding same geographic space covering 4 km2 Artemisa province, Cuba. This area frame urban planning need know topographic characteristics order hydrology behaviour decide best place make roads, building so on. Base still more accurate method, offer pattern test UAS, much flexible solution applications needs detail.
