According to the requirement of City Emergency Response System(CERS),some important problems need to be emphasized,such as technology of information integrated sharing,construction of Public Security "3 in 1" Emergency Response System and Geography Information System(GIS),are analyzed.
The Urban Planning Geographical Information System is one of the important components of the GIS, is it gather with computer and information engineering to urban spatial information and attribute datum to be risen rapidly with desirability of the information social development, store, manage, analysis, use and safeguard newer comprehensive systematic technology, it has offered ration, scientific technological means and method for planning, building and managing of the city, offer auxiliary support for making policy.
From the angle of design and development, introduces the conversion process from AutoCAD to Maplnfo, regarding GIS as technical support, combining the actual demand for the water supply and drain network information system, carrying on the secondary development on the Maplnfo platform and foundation, using and operating Maplnfo by OLE automation technique.
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.
This paper introduces a concept and development of the geographical information system(GIS), and outlines its use program in application to landscape planning and also presents anp useful GIS software by a practical example of landscape suitable analysis.
This paper expounds three points to improve the condition of implementation Shanghai urban planning, there are: deepen understand the inner essential aspects of market economy and urban planning; improve inner condition of urban planning implementation; provide complete and detailed law ensur-ance, set up the GIS of Shanghai metropolis and its regional area to creat a good external conditions.
This paper introduces the development and chracteristics of GIS technology, expounds its applicational prospect and trend in urban traffic planning, in order to promote its practice and improve the quality of planning.
