This schematic shows the Satellite Linked Data Acquisition and Photogrammetry System in concept. The image has several hotspots that bring up a brief text description for the relevant components of the SLiDAP system. The schematic depicts a coastal rookery of some pinnipeds (harbor seals or sea lions as examples). Five imaging stations, comprised of boxes with built-in cameras and solar panel power supplies, are arranged around the rookery, with the cameras pointing at the rookery. The five imaging stations are connected to each other via a wireless Local Area Network, depicted here by "radiolink arrows" linking two of three stations. Another such "radiolink arrow" connects one of the stations to an animal on the beach carrying an archival tag, illustrating the RAT-Link. One of the imaging stations is connected via an VSAT satellite link to a ground receiving station, and from there via Internet link to the laboratory PC. VSAT stands for Very Small Aperture Terminal. This is a common satellite data link system used by many commercial companies. The data exchange through the internet is via File Transfer Protocol or FTP. Three different screens on the PC show the three primary functions of the remote imaging and data collection network: data collection from mobile tags via RAT-Link, photogrammetric census operations (counting animals in the rookery), and creating three-dimensional models of individual animals for the purpose of volume-based body mass estimation.
