Comparativa entre Herramientas de Sistemas de Información Geográfica Libre y Propietario Basada en Metricas de Calidad Desarrollando SIG para Defensa Civil.

Abstract

The comparative study between free and proprietary Geographic Information (GIS) tools seeks to obtain the best development tool based on quality metrics. The deductive - analytical method was applied during the evaluation and fixation of quality parameters based on ISO 9000, ISO 9126-3 standards for quality metrics, quality QSOS for free software and others of the research. The evaluation was done between ArcGis 9.2 as proprietary software and OpenJump 1.2 as open source software; Where OpenJump 1.2 obtained 191.73 points and ArcGis 9.2 218.5 points out of a total of 233 returned by the defined quality parameters, these being: basic functionalities, spatial analysis, raster capability, interoperability, performance, customization, 3D capability, Generation of maps, and documentation and support; With which the best quality GIS tool is determined. With the study carried out, a Geographic Information System for Civil Defense of Chimborazo was developed using the ArcGis 9.2 tool called GIS-DC-RIESGOS, implemented under a Cascada methodology. It involved fieldwork where real locations and information from hospitals, pharmacies, police, firefighters, shelters, gas stations, and alternate emergency and coordination routes were established. Civil Defense accesses the information provided in an agile way by performing dynamic searches of different sites in the face of emergent situations.
