FIGURE 1. Two sites located in the municipality of Enciso (La Rioja). Above, “Virgen del Campo”, below, “Icnitas-4”.
FIGURE 3. Photogrammetric survey of one of the tracks (scale 1:2.5). Initially published in Valle (1993) in black and white. The version presented here is in color, offers more detail, and retains the metric (since it is obtained from the original CAD file while the copy of the article was a photocopy).
FIGURE 7. Interactive thematic map with paleontological information, available on the web cartography server of the Government of La Rioja.
FIGURE 8. GIS environment in which the paleontological information is linked to the orthoimage of La Rioja (both as WMS services). Information is visualized together with a vector file (SHP format) with the perimeters of the Spanish provinces.
