Project Gallery
Explore our visual library of hydrographic surveys, dredging operations, GNSS positioning, river training works, and field deployments — captured during 25+ years of professional practice on the Jamuna, Padma, and Meghna rivers.
Why This Gallery Matters
Professional hydrographic surveying and river engineering are best understood through real-world visuals. This gallery showcases our core field operations — from Multibeam Echo Sounder (MBES) bathymetric mapping and patch test calibration to dredging cross-section analysis, GNSS RTK positioning, and river bank protection using riprap and geobags. Each project reflects our commitment to IHO S‑44 Special Order standards and USACE engineering guidelines.
Browse through the images below to see our equipment in action, understand our data processing workflows, and visualize the scale of our river and coastal engineering projects. Each image links to a related technical hub where you can find detailed guides, calculators, and standards.
MBES Bathymetric Map
High-resolution Multibeam Echo Sounder (MBES) bathymetric map showcasing depth contours, riverbed morphology, and submerged features. Essential for safe navigation, dredging planning, and IHO S‑44 compliant survey deliverables.
