ecotourism as the most attractive subset of the tourism industry can contribute to natural resource conservation and local development. although great numbers of people annually visit abbasabad area, in veresk, mazandaran, to enjoy its brilliant landscape and moderate ecologic condition, there is no applicable plan for many natural attractive zones in this area. as a result, some specific well ...

backgrounds and aims: using geographical information system (gis) can decreases the burden of road traffic injuries effectively by identification of hot spot to modification in hazardous areas. the aim of the study was determining geographical distribution of human risk factors associated with road traffic injuries by using geographical information system (gis) in iran. materials and methods: t...

water use productivity is one of the most important factors in scientific agriculture. it is equal to 0. 7 kg of production per cubic meter of irrigation water (kg/m3) in iran which is very low in comparison with advanced countries (1 to 2 kg/m3). current research studies temporal and spatialchanges of water use productivity in hamedan province in iran using geographic information system (gis),...

The development and application of seismic technology in civil engineering structures is great significance to extend the service life buildings improve overall quality buildings, so it necessary further strengthen research on it. Geographic Information System (GIS) a new subject integrating computer science, informatics, geography other sciences. Because its rapid convenient management massive...

Appropriate technology(AT) has become an integral part if the programmes for decentralized regional development in the third world appropriate techniques are usually low in capital coststhey can be maintained without a high level of expertise, and they do not involve patents, expensive cop...

TLA geographical information system (GIS) is a digitalised mapping process in which data from topographical maps, remote sensing satellite imagery, high-altitude photographs and other maps can be layered and analysed. GIS has been applied to a number of research disciplines because it is an effective means of relating data to geography. An important advantage of using GIS is that layers of unre...

This paper uses a market potential approach to examine the evolution of the rail transport network of China and its spatial distributional impacts on local accessibility, with a particular focus on high-speed rail improvements. Accessibility is measured by using a “market potential” function that was derived from the general equilibrium model of the economic geography literature, and is empiric...

To solve customer complaints better for some telecommunication enterprises, a new method through combined rasterization of Geography Information System (GIS) is presented in this paper. By the combined rasterization of surface features and landforms, the historical customer complaints and the realtime state of network will be utilized to handle new complaints simultaneously. Also, an innovative...

Using solid building models, instead of the surface models in City Geography Markup Language (CityGML), can facilitate data integration between Building Information Modeling (BIM) and Geographic System (GIS). The use however, introduces a problem model simplification on GIS side. aim this study is to solve by developing framework for generating simplified from BIM. In framework, set Level Detai...
