Based On Gis Technology To Build The Agricultural Pattern Display System

According to the request of Shanghai agriculture digital management, use GIS technical to manage all sort of agriculture design. Through visual method to show the achievement of Shanghai whole agriculture status and the eleventh five years plan design. It mainly shows the survey of agriculture in Shanghai such as 100 thousand acres scalable grain field, 100 hectares scalable vegetable, 20 thousand acres leisure fish pond design management, mainly agriculture unit distribution and introduce in the urban, and agriculture entertainment distribution and introduce etc. It can do a reasonable analyze and evaluate for agriculture layout through making use of information technology to realize dynamic showing for agriculture allocation, agriculture dynamic management to improve scientific and standardization of agriculture work. All these will serve for socialist new village construction.This article elaborates on the background of how to select titles for showing system for Shanghai agriculture layout, and application status of DIGITAL SHANGHAI GIS and Sahnghai agriculture. Meanwhile, introduce the research content and important significance of this project.Introduce GIS mainstream development platform, mainly technique and develop tool, development flatform used for this system development, developmemt tool and realization technique. This system development uses GIS technique, and B/S and C/S system. Illustrated by fertile land, do function design, interface design and data-base design.According to user's demand analyse, define the maily content that system need to develop and show the whole agriculture status in Shanghai suburban such as Shanghai agriculture the eleventh five years plan design, maily agriculture units in Shanghai and agriculture entertainment etc. Through system demand analyse to define demand status and showing effect and make a request for showing function, comprehensive enquires, running performance, exised system conformity and future extend.According to the user's development content and demand analyse to set up design principle, system structure design, and net structure design etc for system analyse design.This article design detailedly how to realize primary function, introduce the 2nd development for MapToolkit, and how to realize layer management function and map operating function and map edit functionAgriculture design management is the important content for Shanghai agriculture layout showing system. Using visual way show Shanghai agriculture status and design, which is alos the important part in Shanghai data agriculture establishing. This article set up an high efficiency, serviceability, reusable and flexible Shanghai agriculture layout showing system based on GIS technique.
