Many elements of ancient Maya culture — language, art, ecology, economics, politics — have a geographic aspect and can be profitably investigated through geographic analysis. We are developing a geographic information system (GIS) for the purpose of studying prehistoric Maya settlement and society. The GIS is composed of archaeological, epigraphic, and locational data. It includes the whole May...

GIS (Geographic Information System) is widely applied in many scientific domains. However, to keep the database “current” is still a “bottle-neck” which obstacles the application and promotion of GIS techniques and products. In this paper, we start with the analysis of why the updating of database is difficult and what kinds of the problems exist in GIS database updating. The problems are analy...

Geographic information Systems (GIS) square measure an honest tool for group action completely different form of spacial info. Its provides fast analysis and correlation of assorted geographical contexts. This method planned collects the data and integration marine data kind satellite pictures. This method automatic collects the surface location of the target. The system gets all info concernin...

This paper introduces the characteristics of Geography Information System (GIS) and the actuality and assignment of environmental monitoring. The authors expound GIS applications in ecological monitoring, water monitoring, air monitoring and environmental noise monitoring, then illuminate the vital role of GIS in environmental protection. GIS is the computer information system that can collect,...

This study aims to develop a social media GIS (Geographic Information Systems) specially tailored to information exchange between regions. The conclusions of this study are summarized in the following three points.(1) Social media GIS is a geographic information system which integratesWeb-GIS, SNS and Twitter into a single system. A social media GIS was conducted for the collection of regional ...

Geographic Information Systems visual products have become a powerful resource for Infrastructure Protection and Emergency Preparedness. The utility of informed decision making processes could significantly be improved using 3D web-based GIS visual models. However, collective efforts are needed for further improvement of currently available visual models to address Infrastructure Protection and...

Geographical information System (GIS) has emerged as the core of the spatial technology which integrates wide range of dataset available from different sources including Remote Sensing (RS) and Global Positioning System (GPS). Literature published during the decade (1998-2007) has been compiled and grouped into six categories according to the usage of the technology in malaria epidemiology. Dif...

Geographic Information Systems (GIS) are an efficient and interactive spatial decision support tool for flood risk analysis. This paper describes the development of ArcView GIS extension — namely AVHEC-6.avx — to integrate the HEC-6 hydraulic model within GIS environment. The extension was written in an Avenue Script language and Dialog Designer with a series of ‘point and click’ options. It ha...

ABSTRACT: GIS can significantly contribute to correct interpretation of the signatures of slicks visible on synthetic aperture radar (SAR) images, providing a basis for analysis. Proposed geoinformation approach to oil spill mapping is presented. It includes integration of the geographical, remote sensing, oil & gas infrastructure data and slick signatures, detected in SAR images, in GIS. Vario...

The acquisition of a vast amount of spatial referenced data in professional association football cannot be disregarded any longer in the field of cartography and geo information science. GIS-appropriate data is being captured on a regular basis with sufficient accuracy. The project “GIS-based Football Game Analysis” can be regarded as a contribution and effort in order to share our spatial know...
