The Development Of Land-use Operational Monitoring Using Remote Sensing Database System In Xinjiang Crop Based On Spatial Information

This research is based on national land-use programming,aim at oasis characteristic of xinjiang crop demonstrate area land sorce enviroment,make use of the incorporate characteristic of crop special system and management, consider agriculture, water conservancy, land-use, town construction, ecosystem environment monitor and public safety with meet an emergency reaction of demonstration area. Useing remote-sensing,geography information system and space information service system technique, make use of a 3S technique, investigate, interview with on-the-spot investigation etc. We make shihezi 148 as the main research area,obtain dynamic variety data and real time information of land development,land use,land renovate and land protection, we have designed a database of xinjiang crop land-use and remote sensing inspection based on ArcGIS.We have made on-the-spot inspection and thorough investigation of the demonstration area, obtained the information data of a great deal of foundation geography, and according to need analysis from the data contents, accuracy, present situation...etc. carried on a data source a choice, in the meantime carry on preparing a processing towards setting up database data,.We have used map scan as the numeral method, and carry on a diagram to connect a side, polygon build processing, record into attribute data with note record, adopt a Geodatabase data saving project, establisht database.In the process of database design,we first make a choice of database physical terrace, then designed database setting up project, emphasized to standardize mathed, elaborate the key technique of the database and the concrete method, finally carried on an overall analysis and design to the system function.The system carried out such as traveling extensively, enlarge, contracting of map, all hold, eagle eye, diagram layer control etc. foundation GIS function, also carried out the comprehensive search of attribute data and space data, fixed position, space position calculate, image contrast etc. space analysis.We aim at to concretely need to design covariance function,it can make categorize information of land,and made statistical charts and the special subject diagram output.The system operates interface amity and hand over with each other convenient, the maneuverability is strong.The system adopts ArcGIS series software as GIS farm, and make use of ArcSDE and Oracle to manage and saving data, adoption Visual studio 2008 with ArcEngine of integrated development way, we exertive develop tool in the development of advantage, raised the maneuverability of system.This system passes to make use of a history data and use a ground of demanding analysis to the land, for the our country opens resources in the exhibition land in the northwest region of the comprehensive exploitation provide science basis, is resources in the large unit land development make use of and management accurate information service for decision to provide solid, promote the construction and land resources of'gold soil engineering" of can keep on exploitation.
