The Design Of Implementation Of Land And Resource Management Information System Based On GIS Data Update

The question for discussion is because nowadays prefectural land natural resources information system data renovating too slowly,I amply analyze the plan that the branch renovate land natural resources information system data nowadays and analyse it's problem.For ensuring data renovating,I bring forward that data renovating should be researched from working together system and technology means of GIS.I expect that it has referenced affect to prefectural land branch.At present,the means in the art has not yet correlatively introduce.It can guarantee data enovating duly when it set up land natural resources data renovating system and data renovating skill grow up.This character chiefly resolve that how set up land atural resources data renovating system and adopt which science skill that it apply to data collection and data renovating.It can not ensure data renovating duly and truly if it only depend on lang branch.It must depend on professional branch.The data of GIS can get through setting up working together system of data system,and being conformity new data from different branch data.Another,it can be adopted means base on "3S"compositive.We can find metabolic information duly and get metabolic information duly by rule and line,and duly cut and carve data.It will bring into play information advantage and conformity resource advantage through altogether setting up data storeroom.It is demand of contry information base establishment necessarily.It offer ensuring of data enjoying together.First,it need build standard data system in contry.Each branch abide altogether,consolidate set up.Second,building data institution of data enjoying together,collecting information of each branch.Last,setting up system of Open GIS nationwide,carrying out centralized norm,and coming true data investing of different local.The art of "3S" apply to land natural resources data renovating that is integrate through GPS and RS and GIS.The art of GPS offer different precision airspace site data.The art of Rs offer different precision remote sensing message,offering guarantee for data renovate.The art of GIS build system of different measure space data and decision-making supporting,offering many space analyzing and space demanding and synergic deciding to user.Through researching,it set up data renovating system that mostly obstruction is policy influence,each branch want not to abandon it's benefit.At one time,"3S" compositive skill can not apply to data renovating recently.It has two side reasons,one is moon differentiate rate and identify skill can not guarantee remote sensing image precision can not guarantee big scale special subject chart information;another is remote sensing image and different common GIS data frame obstruct data transmission.
