Meaning technologies today arouse a tremendous interest for the various actors of R&D. One find them, in particular, in the kernel of any application or service implementing dialogue or mediation between software agents and human users, for example in the calculus of cooperative answers. One of the essential keys for these technologies is intelligent and efficient knowledge exploitation by agen...

All the species of Physalaemus Fitzinger, 1826 karyotyped up until now have been classified as 2n = 22. The species of the Physalaemus cuvieri group analyzed by C-banding present a block of heterochromatin in the interstitial region of the short arm of pair 5. Physalaemus cicada Bokermann, 1966 has been considered to be a member of the Physalaemus cuvieri species group, although its interspecif...

The needs of a global citizen may be determined best by educational leadership and policy stakeholders geared towards interdisciplinary Earth Science. Openmindedness, a means to reach collective agreement, may support spatial thinking or GIS education in North Carolina towards a formal K-12 course of study implementation. In particular, A Five-step Plan and Methodology to Introduce GIS to Educa...

This paper will review the status of computer aided teaching advances during the last decade, with a particular emphasis on photogrammetry, remote sensing and GIS. A range of examples will be presented, many of which will be drawn from the Computer Aided Teaching Contests (CATCON), sponsored by ISPRS Commission VI, Working Group 2, during 1996-2006. Consideration of these resources will include...

A major challenge in landscape and environmental modelling is to effectively visualize large amounts of time-series simulation output, often in various Geographic Information System (GIS) formats. We developed a software tool (LANDISVIEW), to easily visualize and animate time-series of ERDAS *.gis maps. The open source tool can also be used to generate batch files for FRAGSTATS, a widely used s...

The aim of this paper is to report a brief history of control actions for Visceral Leishmaniasis (VL) from 2006 to 2010 in the Sanitary District (DS) of Venda Nova, Belo Horizonte, Minas Gerais, Brazil, focusing on the use of information systems and Geographic Information System (GIS) tools. The analyses showed that the use of an automated database allied with geoprocessing tools may favor cont...

The Center for Geographic Information Science (CGISc) at the University of North Carolina Greensboro (UNCG) was established in the Summer of 2006. CGISc is an educational research entity that relies on the use of GIS and the science of geographic information to conduct research on human and natural phenomena distributed on the Earth’s surface. CGISc welcomes interdisciplinary collaboration, and...

Zonguldak Hardcoal Basin is the largest bituminous coal region in Turkey where extensive underground mining activity exists. Because of this activity subsidence effects have been experienced in different locations of the city. In this study, surface deformations caused by the subsidence have been observed by D-InSAR technique using C-Band RADARSAT data. InSAR data process of 16 RADARSAT images ...

Article history: Received 10 October 2006 Received in revised form 9 May 2007 Accepted 9 May 2007 Biodiversity and ecosystem data are both geo-referenced and “species-referenced”. Ecoregion classification systems are relevant to basic ecological research and have been increasingly used for making policy and management decisions. There are practical needs to integrate taxonomic data with ecoregi...

GRASS GIS (Geographical Resources Analysis Support System) is a free, open source software and has been used for Remote Sensing (RS) and Geographic Information System (GIS) data analysis and visualization. Inside GRASS, different modules have been developed for processing satellite images. Currently, GRASS uses databases to handle large datasets and the performance and capabilities of GRASS for...
