Animation-Based Learning Spatial Analyses Used in Geographical Information Systems

Prominence of Spatial Database in Geographical Information Systems

Spatial Database is a collection of spatially referenced data that acts as a model of reality. Geographical Information System includes spatial data which is either in raster or vector form and data derived from remote sensors are increasingly utilized as source for GIS. Spatial data is the core part of the Geographical Information System. Data mining techniques are studied to discover knowledg...

A Non-geographical Application of Spatial Information Systems in Pupillometry

Spatial analysis and spatial information systems have great potential in many nongeographic domains. This paper presents an example of the utility of spatial analysis in a non-geographic domain. A technique of pupillometry using digital infrared video loosely coupled with a Spatial Information System and a spreadsheet is developed to accurately quantify pupil dilation magnitude and constriction...

Location based services using geographical information systems

One of the most obvious technologies behind Location Based Services (LBS) is positioning, with the most widely recognized system being the Global Positioning System (GPS). There are, however, other means of positioning in addition to GPS. These other technologies are network based positioning and typically rely on various means of triangulation of the signal from cell sites serving a mobile pho...

E-learning Curricula Search in Geographical Information Systems and Science

This paper addresses the process leading to curriculum revision in post-graduate studies of GIS&Sc within the ISEGI-UNL. The project aims to determine an e-learning curriculum proposal, able to provide an answer to a set of challenges of different nature. The proposed framework suggests the need to consider the current process of curricular revision according to: the major reforms taking place ...
