Abstract
Taking the survey work at the preliminary design stage of the Longjiang River Valley Irrigation Zone Proj-ect as an example,this paper explores the DLG production mode that combines UAV aerial survey with the collabor-ative application of two software of MapMatrix and Haochen CASS.Through field mapping and supplementary sur-vey,the accuracy and completeness of the topographic map results are effectively guaranteed.This workflow not on-ly significantly improves the surveying and mapping efficiency,but also achieves cost control.关键词
