An Introduction to Free Geographic Information Systems in Fisheries Science

Introducción al Sistema Gratuito de Información Geográfica en ciencias pesqueras

Abstract

Geographic information systems (GIS) are powerful tools for analysis and interpretation of spatial data commonly encountered in fisheries science. We presented details of GIS use in fisheries management in a prior study and found cost to be a factor limiting GIS use. This article introduces fisheries managers to free or open-source GIS. Free or open-source GIS are readily available, powerful tools capable of performing a variety of spatial analyses. We strongly encourage managers wishing to perform spatial analyses, but who are unable to purchase software, to consider free GIS.

Los Sistemas de Información Geográfica (GIS) son una herramienta poderosa para el análisis e interpretación de datos espaciales comúnmente encontrados en la ciencia pesquera. Se presentan los detalles del uso del GIS en el manejo de pesquerías aplicado en un estudio previo, encontrando que el costo era un factor que limitaba el uso del GIS. En este artículo se introduce a los manejadores de pesquerías un GIS gratuito o de acceso abierto. Este GIS gratuito ya está disponible y contiene herramientas poderosas, capaces de realizar una variedad de análisis espaciales. Se recomienda ampliamente a los manejadores que deseen realizar análisis espaciales, pero no puedan comprar el software, a que consideren el GIS gratuito.
