Here at The Mapping Network, we understand the challenges and costs associated with locating and removing sediment. We specialize in accurately mapping bodies of water, calculating the water volume, collecting sediment depth samples at critical areas and monitoring the distribution of sediment over time. Common questions from our clients: Where is the highest sedimentation occurring? How much fluffy sediment (in cubic yards) is in each cove? If the lake is drawn down 5 ft, what…
When thinking about mapping a lake, it’s good to have a basic background of how the different methods of GPS can affect the quality of your data and ultimately the accuracy of your map. Staff at The Mapping Network have been using GPS technology to map lakes since the 1990’s and we want to quickly cover some basics about the primary GPS collection methods available today. It is important to understand how each type of…
