This article takes Surveying control achievement(GPS,wire,triangle,standard) as the research object,Systematically elaborated the technology and the method of using geographic information system(GIS) theory and the data bank technology establishmenting surveying control achievement management system,And on its function、structure has given the specify,And it Has realized to the Surveying control achievement attribute data and the graph data centralized management.
This paper introduces the applied Global Position System (GPS)、Remote System (RS) and Geography Information System (GIS)(called"3S") techniques as representative surveying and mapping of the modern digital technique system, carrying 1:2000 scale lands make use of the product of the present condition inquiry to carry out the process on YiWu of Zhejiang Province.
With geographic information system (GIS), the ecological water requirement for forests in the Jinghe watershed, western China was estimated.
Employing Arc/Info GIS, the tree species diversity and rarity, disturbance degree, protection of channel system, and classification management in the Maoershan National Forest Park were described, and used as the input factors of NN.
Division of afforestation site type in the watershed of Wangjiagou, West Shanxi through GIS
The results show that we can model the spatial changes of vegetation suitability with a combination of topographic analyses based on DEM and GIS functions.
We also demonstrate these spatial changes on the screen using Visual Basic language and GIS functions, which will help decision makers to have a clear view of species and site suitability changes over large areas.
