Comparação entre valores de altitude estimados através dos dados ASTER e SRTM, visando aplicação em áreas agrícolas.

Abstract

A Digital Elevation Model (DEM) for the State of São Paulo was made using digital images of ASTER sensor having a spatial resolution of 30m. This model was compared statistically using the Kolmorov-Smirnov test with other model based on SRTM (Shuttle Radar Topography Mission) data where the spatial resolution is equal to 90m. The results showed that both models have the same distribution with 95% of confidence.
