DIGITAL ELEVATION MODEL VALIDATION WITH NO GROUND CONTROL: APPLICATION TO THE TOPODATA DEM IN BRAZIL
(Univ Federal Parana, Centro Politecnico, 2014-04-01)
Digital Elevation Model (DEM) validation is often carried out by comparing the data with a set of ground control points. However, the quality of a DEM can also be considered in terms of shape realism. Beyond visual analysis, ...
Segmentação de dados de perfilamento a laser em áreas urbanas utilizando uma abordagem Bayesiana
(2007-01-01)
In this paper is presented a region-based methodology for Digital Elevation Model segmentation obtained from laser scanning data. The methodology is based on two sequential techniques, i.e., a recursive splitting technique ...

Evaluation of 1D hydraulic models for the simulation of mountain fluvial floods: a case study of the Santa Bárbara river in Ecuador
(2019)
River flooding is a key topic for water managers because of social and economic losses it can cause. The complex topography and dynamics of mountain rivers has limited the analysis of their behavior during flood events ...
