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...

This paper describes a newly developed statistical approach for modelling positional error of geometric features in GIS. The generic statistical models for N-dimensional features are ® rstly derived. The models for oneand twodimensional features are then developed as the speci® c cases of the generic models. In each dimension, the GIS features are classi® ed as points, line segments and line fe...

In this work, in experimental phase, the digital elevations models (DEMs) appear as a fundamental tool for studying erosion of the land in a concrete zone of agricultural production, olives production. Collected data from the zone of study in different campaigns are used to determine possible variations in the orography of the land. GPS is the used tool to measuring coordinates of points in the...

AtmoGIS should enable the integration of atmospheric models and GIS management, analysis and visualization functions. This paper will present a first prototype of an interoperable GIS framework. The prototype is implemented based on an object-oriented database kernel and a system for scientific visualization, both of which are capable of supporting time-varying 3-D data. Using a meteorological ...

GIS and Modeling Overview MICHAEL F. GOODCHILD NATIONAL CENTER FOR GEOGRAPHIC INFORMATION AND ANALYSIS UNIVERSITY OF CALIFORNIA SANTA BARBARA, CALIFORNIA Modeling can be defined in the context of geographic information systems (GIS) as occurring whenever operations of the GIS attempt to emulate processes in the real world, at one point in time or over an extended period. Models are useful and u...
