GIS can only be applied to certain areas by storing format. It is subordinate to a system when displaying geographic information data. It is therefore inevitable for GIS to use GML that supports efficient usage of various geographic information data and interoperability for integration and sharing. The paper constructs VisualGML that translates currently-used geographic information such as DXF ...

For more than ten years MECOSIG has been used as a method for GIS design and implementation in various national and international projects achieved in our laboratory. During a decade, the method has been progressively improved and extended without modification of its basic principles. However the emergence of distributed GIS, implying several organizations capable to play various roles, require...

A new solution to detect and define the coordinate system of gis data based on geographic names automatically is presented. GIS-Users with almost no knowledge of coordinate systems and projections have often problems to integrate gis data in their projects, because the datasets have a wrong, or no projection definition. Since the solution works in the Austrian Service for Torrent and Avalanche ...

Locating usable spatial data is essential for the application and use of Geographic Information Systems (GIS). GIS data collection development constitutes a core element of GIS services within academic libraries. Managers of geospatial resources require a fundamental understanding of the nature and use of GIS data. In the creation of a GIS collection development policy, library professionals sh...

particulate and gaseous emissions of pollutants from industries and auto-exhausts are responsible for rising discomfort, aggravates respiratory and cardiovascular. in this study, a system for air quality information in tehran city has been developed, using an online web-based geographic information system. this web-based gis application allows users to recognize areas with a potential increase ...

Before addressing the diverse functionalities that can be found in Geographic Information Systems (GIS) today, a definition of a geographic information system, its purpose, and its general architecture shall be given. The different forms of GIS that are found in today’s ever-expanding range of information technology tools will therefore be discussed in Sect. 6.1. The core of each GIS is constit...
