| Resumo | Digital elevation models (DEM) are numerical representation of terrain elevation data that has been used in a wide range of spatial analysis applications. The principles for acquisition, storage, management, update, spatial analysis, visualization as well as integration with other systems are reasonably well known. However, as DEM applications are becoming increasingly more widespread, so does concern about the quality of the available elevation data and the propagation of DEM errors through the analysis. Currently available DEMs frequently report only the average magnitude of errors as the root mean square error, which does not provide information on systematic bias nor on the spatial patterns of the DEM errors. The present work deals with DEM generated by synthetic aperture radar (SAR) interferometry (InSAR) and the main goal is developing a method for DEM correction that can be flexible and adaptive to local errors magnitude variations. The approach used in this work consists in SAR data acquisition, field topographic control structure determination, original DEM models geometric quality evaluation, development of strategies and algorithms for DEM error correction and calibration. Implementation of strategies and algorithms required to solve the problem was taken in IDL (Interactive Data Language) environment. The core of the methodology for DEM error correction and calibration intends to provide a DEM fitting to geographic space reality by calculating and incorporating error compensation surfaces generated by triangulation with linear interpolation and inverse squared distance interpolation methods. The DEM calibration methodology also includes determination of statistical spatial pattern accuracy parameters for processed DEM. The assessment of correction efficiency is done by analyzing statistical quality data extracted from fitted DEM that provided measures of DEM accuracy. Results revealed that DEM considered in analysis, like many other currently available, have local and global errors and needs to be corrected before their uses in posterior analyses applications. Final results also shown that application of proposed correction method, besides improving DEM geometric quality, also provided statistically confident numerical estimation of DEM global and local accuracy. |
