The 3 cameras offer different viewpoints of La Arena, which are refreshed every hour…
SNAP: These are snapshots or traditional photographs that give timely information about the characteristics of the study area but do not permit obtaining quantitative information.
TIMEX: These are the result of integrating 600 snapshots taken at 1-second intervals during 10-minute periods. These images afford quantitative information; as, for instance, the location of the coastline, sand bars, the intensity and direction of currents, etc.
RECTIFIED TIMEX: This image is achieved by converting the information obtained from the oblique images into a flat, metric image, using photogrammetry techniques. The video images from the different cameras are rectified and merged.
