The idea is to introduce a fast and accurate method of collecting inland bathymetric data in Poland by means of a specially equipped autonomous measuring platform. Thanks to newly developed, low-cost GNSS devices capable of high-frequency measurements, this system collects data on a predefined track with sufficient accuracy. In other words, the platform is navigated by a satellite positioning system, while the various tools and equipment installed on it make it possible to secure its movement and record depth data on the designated route. The result is fast and precise data collection, easy updating of existing datasets, and low-cost terrain campaigns. This data enables us to produce high-quality bathymetric maps for water navigation and angling. Such bathymetric maps could be easily implemented in most of the existing land-navigation software. This would give a huge group of users – especially sailors, anglers, and divers – access to a dual-use navigation system suitable for both routing on land and various activities on water.
