We seek to evaluate the potential for archaeological purposes of a set of LiDAR data, with a density of 0,5 points per square meter, made publically available by the Spanish National Geographic Institute (IGN) in the framework of the PNOA (Plan Nacional de Ortofotografía Aérea) project. This data will be compared with other available LiDAR datasets with a higher point density. Different case studies in Northwest Iberia will be presented.
