Web GIS (Geographic Information Systems) service systems provide the various GIS services of analyzing and displaying the spatial data with friendly user-interface. But, early systems don’t support open environment and interoperability. It is difficult to access diverse data sources, which provide each spatial data format. And, these systems have the difficult of upgrading the function and redu...

The assessment of natural, cultural and human resources, in the context of the growing importance of environmental studies, creates a large amount of multidisciplinary data. This should be integrated and analysed so as to evaluate and manage the resources, as well as to model their internal and external relationships. Nowadays the necessity of handling, integrating, analysing and updating data ...

a r t i c l e i n f o Keywords: BIM GIS FM Integration Surface model BG-ETL In this study, we propose software architecture for the effective integration of building information modeling (BIM) into a geographic information system (GIS)-based facilities management (FM) system. This requires the acquisition of data from various sources followed by the transformation of these data into an appropri...

Domestic waste water treatment using Onsite Sewage Treatment and Disposal Systems (OSTDS) (also known as septic systems) is a source of nitrogen contamination in groundwater and surface water. Estimating nutrient load from septic systems as a storm water source to surface water bodies is important to reduce nutrient load in support of Total Maximum Daily Load (TMDL) programs. Software packages ...

Remote Sensing (RS) and Geographic Information System (GIS) education and implementation is rapidly being adopted by universities in developing countries, such as the United Arab Emirates (UAE). Until recently, the use of GIS and RS in education in the UAE was hindered by the cost of hardware and the complexity of software. With the price/performance increase of desktop computer capabilities an...

constructionof underground dams is a practical solution to save groundwater in alluvium watersheds, particularly in arid and semi-arid regions where surface water scarcity is an environmental challenge. considering socio-economic and environmental benefits of underground dams, the accurate locating is the primary consideration for dam construction. the new technologies and methods are a step to...

Geographic information systems are becoming more popular for end-user and decision support system construction but they incorporate software and concepts with some inherent problems for end-user computing. This paper identifies several concepts developed during the construction of one end-user GIS that can be incorporated in a wide range of end-user GIS. The approaches make extensive use of met...

A prototype geographic information system (GIS) for the analysis of motor vehicle collisions in Honolulu, Hawaii, is described. An overview of GIS hardware and software is provided along with criteria utilized in the development of the Hawaii system. Mapping and spatial data sources relevant to traffic safety are described and evaluated. The usefulness of Census Bureau Topologically Integrated ...
