Lake & Pond Mapping (Hydrography)

What is hydrography? In simple terms, we measure, model, and describe the physical features of water bodies as well as predict change over time. Hydrographic mapping quantifies the depth and form of the reservoir floor utilizing a variety of sonar systems.

The Mapping Network has years of extensive experience in various inland, freshwater environments. We have a proven track record in providing high-resolution hydrographic mapping that complies with International Hydrographic Organization (IHO) standards and US Army Corps of Engineers EM 1110-2-1003 standards.  Our quality assurance and quality control (QA/QC) procedures meet or exceed local, state, federal and country requirements.  

Throughout the years, we have invested heavily in mapping equipment.  All of our sonar equipment records “backscatter” allowing our analysts to review and ensure the sonar is tracking the reservoir floor.  This is crucial to the accuracy of the map because of the various factors that can interfere with the sonar (vegetation, liquid sludge, etc). 

Hydrographic information has a variety of uses including a baseline for monitoring sediment, water volume, management, biologic, and dredging activities.

The Mapping Network’s philosophy of high standards and accountability does not end with mapping equipment and practices. We also recognize the importance of post-processing methods, modern reporting and data display to benefit our partners and clients over-all end goals.
