The Geographical Information Systems (GIS) represent a power ful tool in many scientific fields, included
the volcanology. The present work shows its application to the Holocene volcanism of Gran Canaria
(Canary Islands) with an example of El Draguillo volcano. The inclusion of all the geological data (detailed
cartography, geochronology, petrology, geochemistry, etc) of this volcano in a GIS provides a better
visualization of its spatial-temporal evolution by means of the use of high-precision topographic data
