Xia Qibin · Hydrographic Surveying and Charting · 2013
The calculation of hydrographic survey w orkload is a basic job of the hydrographic scheduling and task management.In the past,it has been completely by hand operation,its w orkload is heavy and the accuracy is not high.This paper discusses the main research content of the automatic calculation system based on GIS technology,and in-depth analysis on the key technical issues related.Using the mature space operation algorithm in GIS technology,the system can automatic extract、union、clip、extend all kind of polygon element to achieve the automatic calculation of the w orkload.The system can replace the cumbersome manual operation to improve the management efficiency of surveying and mapping production.
