This paper presents research in Geographic Information Systems interoperability. Also, paper describes our work in development, introduces interoperability framework called GeoNis, which uses proposed technologies to perform integration task between GIS applications and legacy data sources over the Internet. Our approach provides integration of distributed GIS data sources and legacy informatio...

Geographic Information Systems (GIS) require the power of sophisticated database management systems for efficiently managing the persistency and consistency of huge amounts of data. A pool of software tools takes care of the production process, which consists of editing, visualising and selecting geographic data. However, the quality of the data – its well-formedness and integrity – is not so e...

Incorporating the temporal element into traditional GIS is a challenge that has been researched for many years and has many proposed solutions. The implemented system “Extended Dynamic GIS” or EDGIS is based on the “geo-atom” and Space Time Point (STP). EDGIS provides a platform for spatiotemporal data representation, storage, and query in order to address the need for a dynamic GIS to manage c...

A new era has been started in urban and natural resource management when GIS (Geographic Information Systems) was put in use in Canada in 1971. Although, it was not possible to store and update the data desirably in the early times due to the deficiencies in computer hardware and software, those tasks that were difficult and time-consuming to fulfill by traditional techniques began to be perfor...

LINK TO PAPER The Challenges of Implementing Enterprise GIS at the City of Fort Worth Track: State and Local Government Author(s): Len MacKenzie During the past year, the City of Fort Worth, Texas has been implementing an enterprise GIS based on ESRI's suite of software products. This paper will give an overview of the technical and administrative challenges involved in coordinating enterprise ...

In the mid-1990s, several critical texts raised concerns about the social, political, and epistemological implications of GIS. Subsequent responses to these critiques have fundamentally altered the technological, political, and intellectual practices of GIScience. Participatory GIS, for instance, has intervened in multiple ways to try to ameliorate uneven access to GIS and digital spatial data ...

Humanity has faced an enormous technological evolution over the last 15 years in the area of Networks and Communications, in parallel with the continuous progress occurring in the computer hardware and software technologies. Communications and Informatics are undoubtedly considered as the fundamental sections for developing systems and managing their critical component, the data, in order to ob...

Mobile GIS emerged in the 1990s, with integration of GPS is one of the leading technique. It is a Location Based Services which can be defined as any application that extends spatial information processing or GIS capabilities to end users (based on their geographic location) (ESRI 2000 & 2001d). In other words it can be used to gather information from any place, and in no time. It’s where wirel...

environmental characteristics, including the quality of green spaces, constitute one of the determinants of buildings (house & apartment) transaction prices. in this research, impact of urban green space on building's transaction prices (rials/m2) in karaj region, district 1 (jahanshahr), was analyzed. therefore, a questionnaire concerning building characteristics and transaction prices wa...

Species Distribution Models (SDMs) are correlative models that use environmental and/or geographical information to explain patterns of species occurrences. Those models are being used in various fields including climate change, invasive species research, evolutionary biology and epidemiology. Thanks to the availability of increasing computational resources, new methods continue to be developed...
