| Abstract | validação de modelos digitais de elevação (MDE) consiste geralmente na comparação dos dados com um conjunto de pontos de controle. Porém, a qualidade de um MDE também pode ser considerada em termos de realismo das formas. Além da análise visual, pode ser verificado que propriedades físicas e estatíticas do relevo terrestre são cumpridas. Essa abordagem é aplicada a um extrato do Topodata, um MDE obtido pela reamostragem do MDE SRTM sobre o território brasileiro com uma abordagem geostatística. Vários indicadores estatísticos são calculados. Mostram que a qualidade de Topodata em termos de descrição das formas é melhorada com relação ao SRTM. ABSTRACT: 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, it can be verified that physical and statistical properties of the terrestrial relief are fulfilled. This approach is applied to an extract of Topodata, a DEM obtained by resampling the SRTM DEM over the Brazilian territory with a geostatistical approach. Several statistical indicators are computed, and they show that the quality of Topodata in terms of shape rendering is improved with regards to SRTM. |
