Application of ArcGIS In the Evaluation of Land Intensive Use

Abstract

Abstract-Land intensive use is essentially the relationship between land input and output, which means to get the highest output with the least input. The evaluation of land intensive use level is a vital content of urban land management, which can help to provide scientific basis for the governments' decision-making of land management. As a key tool of spatial analysis, ArcGIS plays a very important role in the evaluation of land intensive use. On the basis of discussing the importance of applying GIS to the evaluation work of land intensive use, this paper taking the work flow of the evaluation of intensive land use as the order to introduce the application of ArcGIS in the evaluation work, including image matching, data editing and production of thematic maps, etc., and puts forward the idea of optimizing this work in the future in order to provide reference for theapproaching evaluation of land intensive use and the application of ArcGIS software.Keywords-Land evaluation; ArcGIS;Geodataset; Element class; Featureclass I. FOREWORD It is a great important strategic period now that in China, in which we have both opportunity and challenge in social development, and the pressure of land use will be strengthened. A intensive and efficient land use model in the development zone must be established to ensure a sustainable development of society and economy and to ease the contradiction between land supply and demand. The land intensive utilization evaluation work for the development zone can efficiently control blind expansion, help to tapping the potentiation of inefficiently-use land, enhance the ability of land to participate in macroeconomic regulation and control, and have great significance in building a resource-saving society .In the past, operatorsis usually conduct data statistics and graph calculation and drawing work usually in the Office software and the AutoCAD platform. This kind of work mode has the advantage of simple operation, wide range of application,but the disadvantages are also obvious. Two separate work platform to the combination of graphic and attribute is not close, which often leads toa result of a difference between the final statistical results and the actual measured data.This will load heavy work to check. But with geographical information system (GIS) as a representative of modern science and technology, which can well achieve information acquisition, data processing, space application of automation, intellectualization and visualization,this kind of problem can be easily solved. II. APPLICATION OF GIS IN THE EVALUATIONOF LAND INTENSIVE USE ArcGIS software is now one of the mostmainstream software in the area of geographic information engineering.It is a full range of the highest level of GIS products successfully launched by ESRI Company after the company integrated GIS with database, software engineering, artificial intelligence, network technology and othermainstream computer technology.In the process of land intensive use evaluation,generally the planning departments will provi...
