Abstract: An augmented reality boating and fishing system includes a client device comprising a client application, a computing system comprising a server-based application and a database datastore comprising topobathy data that are presented as data elevation model (DEM) data of a water body. The client application accesses the server-based application and the database datastore via a network connection. The server-based application includes an augmented reality (AR) engine, a computing algorithm, and a rendering engine. The AR engine receives the DEM data of the water body and environmental factor inputs and uses the computing algorithm to calculate fish probability distributions of various types of fish within the water body. The rendering engine fuses the calculated fish probability distributions and DEM data and generates an AR composite image that is viewed via the client device.
