The Mapping Network is a nationwide group of professionals providing the highest quality and most affordable bathymetric, sediment and asset mapping products on the market today. The Mapping Network has partners located throughout the county working directly with recreational property owners, lake associations, engineers, golf courses, marinas, developers, governmental organizations, and fishing clubs. A local expert aquatic service provider understands the dynamics of a lake to determine the best transect paths to precisely model the lake's bathymetry. With 12 years of experience in the bathymetry mapping profession, our highly trained staff understand and employ the latest technology trends to generate a bathymetric map that is amazingly accurate and also aesthetically enjoyable. www.themappingnetwork.com info@themappingnetwork.com

2. Lake Mapping Program
 The Mapping Network (TMN) is an industry leader in
Geographic Information Systems (GIS) Consulting, Data
Conversion, and GPS Data Collection.
 TMN specializes in terrain and sub-surface (bathymetry) GPS
mapping
 Our experienced staff have been using GIS and GPS
technology for land and water services since 1995
 TMN has developed proprietary technologies for data
collection, analysis and map generation
 A select group of professional lake management companies
throughout the nation have been chosen to provide lake
mapping services

3. Lake Mapping
 Bathymetry or Bathymetric Mapping –
the study of underwater depth, of the third
dimension of lake or ocean floors. A bathymetric
map or chart usually shows floor relief or terrain
as contour lines, and may additionally provide
surface navigational information.
Location = x and y
Depth = z

4. Lake Mapping Process
 Integrates GPS (Global Positioning System) with sub-foot
(30 cm) accuracy and Sonar equipment.
 Provides a location (x,y) and a depth (z) every two
seconds.
 Import 3D data points (x,y,z) into customized software
program where highly skilled analysts produce a 3D
model.
 Once a 3D model is built several calculations and
information products can be produced, including water
volume, average depth, sediment volume and even how
many gallons of water it would take to raise the water
body by a inch.
 The Mapping Network produces industry leading
bathymetric maps with unsurpassed accuracy.
