This study examines the use of image processing and remote sensing in landuse changes mapping for Palladam Taluk between 1972(Topographic sheets) and 2011(satellite images). The layers of landuse map (1972) were digitized by heads-up digitization method in Quantum GIS (QGIS) software environment. Similarly the layers of landuse map (2011) were developed by supervised classification of satellite...

Two complementary GIS-based functions are designed and implemented to assess the expected degree of loss due to the occurrence of flood events. Each function processes institutional thematic layers and allows decision makers first to quantify the physical and the economic exposure of the elements at risk in a given study region and then to assess the expected degree of economic loss in relation...

The growing popularity of Free and Open Source (FOSS) GIS software is -without doubtsdue to the possibility to build and customize geospatial applications to meet specific requirements for any users. From this point of view, QGIS is one of the most flexible as well as fashionable GIS software environment which enables users to develop powerful geospatial applications using Python. Exploiting th...

FREEWAT is an ongoing GIS environment to serve as preand post-processor for running simulations of surface-/groundwater interaction, with the possibility to activate several features accounting for the different water stresses. This paper reports the capability related to address water resource management problems, by activating management tools available in the MODFLOW-OWHM code. The latter is...

INTRODUCTION GIS continuously increase in complexity, more and more data are created as much features developed to treat them. On the user side, GIS software is now integrated in several processes such as emergency management. In this article, we study how novel Human-Computer Interaction (HCI) techniques can improve GIS usability, especially for making command selection easier and for enabling...

A growing body of literature explores the relationship between the built environment and health, and the methodological challenges of understanding these complex interactions across the lifecourse. The impact of the neighbourhood environment on health and behaviour amongst older adults has received less attention, despite this age group being potentially more vulnerable to barriers in their sur...

The quantification of landscape structures is an important part in many ecological analysis dealing with GIS derived satellite data. This paper introduces a new free and open-source tool for conducting landscape ecology analysis. LecoS is able to compute a variety of basic and advanced landscape metrics in an automatized way by iterating through an optional provided vector layer. It is integrat...
