地理国情监测中常见的技术问题与解决方法
摘要
Abstract
Geographical national conditions monitoring aims to build a natural resource monitoring network to achieve real-time,dynamic and accurate monitoring and analysis of national conditions information such as land resources,environment and natural disasters,and provide scientific basis for national decision-making.In actual production tasks,various data and technical problems are often encountered.This paper sorted out various problems encountered by Lanzhou City in the production of geographical national conditions monitoring tasks,adopted the"external-internal-external-internal"operation method,completed the collection of remote sensing interpretation samples before the formal collection of data,and during the survey.Other reference images were taken as a reference basis for later interpretation and classification of internal industry.Make full use of high-resolution,high-current remote sensing images,combined with preliminary census orthophoto images,to provide accurate data sources for monitoring geographical conditions.The research in this paper is conducive to improving the efficiency of geographical national conditions monitoring,providing technical reference for colleagues to solve various problems,promoting the technological development of the surveying and mapping industry,and providing scientific guidance for geographical national conditions monitoring.关键词
