La aplicación de los sistemas de información geográficos (GIS) en el desarrollo de un índice de idoneidad para la prospección de fósiles de tetrápodos en el municipio de Lourinhã
Palabras clave:
Territorial planning, Dinosaurs, Lusitanian Basin, Upper JurassicResumen
Paleontological prospection campaigns are traditionally planned around
previous knowledge of sites that have provided fossils and the interpretation
of the regional geology. The application of a suitability index developed for
the study of other rock formations (e.g. Two Medicine Formation, in Canada
and USA) in the Upper Jurassic deposits of the Lourinhã municipality (Portugal), we determined areas with a higher likelihood of providing tetrapod
fossils. The index was built using geospatial data, and through the usage of
a weighted sum it was possible to determine the values of the suitability index, and then project them unto a map of the municipality of Lourinhã. The
total area of the municipality was divided according to different suitability
indexes: lower (overall area of 29,55 km2
), medium (overall area of 78,56
km2
) and higher (overall area of 39 km2
). The application of these methods
allows considering distinct factors beyond the geology that can speed up the
decision-making process for prospecting and land management.
