Echogram in action
By Marek Grzybowski
Echogram, Member of the Baltic Sea and Space Cluster, finished a busy year in 2024. Echogram, led by Maciej Lang, goes full steam ahead in 2025. The company has been operating on the market since 1997. The main activity of the company is focused on hydrographic research.
These include: – bathymetric research – collecting and processing data using a single-beam or multi-beam echosounder, – locating underwater objects (in order to clean the seabed) using a high-frequency side sonar, building three-dimensional numerical models of the seabed. The research is carried out in accordance with hydrographic (IHO SP44) and geodetic standards. Below we present the results of some of the research.
Echogram finished integrating our unmanned surface vehicle (USV) with the compact hashtagEchologger ECT D032 dual-frequency single-beam echosounder. This device works at 30 kHz and 200 kHz, recording both frequencies at the same time and covering the entire water column. As a result of this integration, we conducted measurements on the Vistula River in Płock, gathering detailed data on sediment distribution.
The year 2024 was particularly fruitful. Measurements made from our survey boats in seaports on the Polish coast using multi-beam echosounders, remotely operated vehicles and photogrammetric drones.
Exploring Poland’s Ports – Starting with hashtagFrombork
Frombork, located on the Vistula Lagoon, is a small but significant port with a lot to offer. Its technical parameters include:
– Depth: Up to 2.5 meters, suitable for smaller vessels.
– Berths: Dedicated space for fishing boats, yachts, and passenger traffic.
– Facilities: A marina equipped with basic amenities for sailors and visitors.
Though modest in size, Frombork’s port plays a vital role in supporting local fishing and tourism while offering a picturesque gateway to the Vistula Lagoon.
Echogram completed a project to prepare new bathymetric maps for the following lakes: Patnowskie, Mikorzynskie, Lichenskie, Slesinskie, Wasoskie and Goslawskie in 2024. Data were collected by our measurement teams using a multi-beam echosounder, a remotely operated vehicle (USV) equipped with a single-beam echosounder, and an AUV drone equipped with a photogrammetric camera.
The data was prepared for PL-2000 / PL-EVRF2007-NH systems. At the same time, the height control points were reopened and the connection of water gauge staffs on the lakes was checked.
