Zhao You-son · Cehui kexue · 2015
Aiming at the particularity of the products of coastal island(rock)DEM and the current status,that the method study of their quality inspection is insufficient,based on the analysis of traditional quality inspection methods of DEM data,the paper put forward a set of technical methods suitable for large quantities of the product quality inspection for coastal island(rock)DEM:data quality test index was researched according to the products of coastal island(rock)DEM quality model,and test method of the different quality index was discussed;quality index which can be tested by program was distinguished,and by establishing inspection rule library,the automatic batch check for section check items was realized;and then indoor and outdoor work was divided,which could improve the human-computer interaction method for check items.Finally,based on the quality inspection for more than 3000 pieces of the products of coastal island(rock)DEM,the result showed that the technical route proposed in this paper would be feasible with objective and truequality evaluation results.
