Morphometric analysis is used to understand the hydrological process and assessment of characteristics surface water basin. In present paper, an attempt has been made study detail morphometric Kulbera Daurighara river basin, which are tributaries Subarnarekha River in Purulia district, West Bengal. For detailed study, SRTM data for preparing digital elevation model (DEM), Geographic Information...

This work investigates the practical issue of mapping existing GIS to the OpenGIS standards. We describe the data models used in three systems (MGE, ARC/INFO and SPRING) and analyse the problems involved when mapping them to OpenGIS. Our conclusion is that the OpenGIS standard has not been defined in a formal and unequivocal way, and therefore, there are indefinitions and competing alternatives...

Sieber 15 Introduction Increasingly nonprofits are following the lead of public agencies and private industry by implementing a GIS. They are drawn to a GIS because it can combine large amounts of data from disparate sources and on different media, order them into layers or themes, and analyze or display various relationships. The greater promise of the technology, to nonprofits such as grassro...

This paper presents a study on the feasibility, mechanisms and key technology for integrating GIS and OA in the Browser/Server (B/S) architecture, on the basis of a comparative analysis of the independent development model and the integrated development model of GIS and OA. Presently, the development of GIS and OA is mainly based on the two models: Mainframe-Terminal (M -T) model upon stand-alo...

In previous empirical work humans did not recognize the definition of most topological operators for regions by their names in two geospatial information systems (GIS). This work differentiates the not corresponding definitions and comprises more topological terms in order to find better term/definition matches. The main hypothesis is that the majority of acceptable matches – defined as matches...

The complex and proprietary nature of geospatial data makes them almost non-sharable among large user community. GIS interoperability is necessary for realizing a successful spatial data infrastructure. With the advancements of web service technology, GIS interoperability has made a paradigm shift – from monolithic GIS providers to distributed geospatial services. The applicability of web servi...

The social implications of GIS have been debated over the past five years among scholars in several disciplines. GIS have been either conceived by practitioners as value-free, neutral tools for problemsolving or castigated by critical social theorists as socially biased technologies serving only corporate and state interests. Neither of these polarized views is very helpful in understanding the...

Public Participatory Geographical Information Systems (PP GIS) is a field of research that focuses on the use of GIS by the general public and aims at involving citizens in a decision-making processes. PP GIS applications increasingly use the Internet as a platform for communication and dissemination of information. They link community participation and geographic information in a diversity of ...
