The technique, based on body patterns, could potentially be informative studying seasonal occurrence of giant sunfish alexandrini ) Bali reefs (Indonesia), where this species an important drawcard local SCUBA diving tourism.

Laser altimeters are commonly used in planetary research for their high geodetic accuracy. A key procedure processing of laser altimeter data is the geolocation. In this process, time-of-flight measurements converted to coordinates pulse footprints on surface target body. Here, we present a consistent and systematic formulation three geolocation models with increasing complexity: static model, ...
