Design and implementation of consistency inspection of framing DEM edge elevation
DEM products are important parts of 3D real scene construction in China,and they are very important for qualified DEM products making to ensure the quality of data products.The method and technical process of edge inspection for DEMs in the same projection zone and across projection zones are designed in this paper,and the corresponding checking program is developed to meet the requirements of edge inspection for DEMs in the same projection zone.The experiment shows that the proposed method can accurately identify the elevation value inconsistency error at the edge of DEM,and it is of great significance for operators and quality inspectors to quickly determine the quality of data products.
