• Adding the third dimension to a mapping project can take the power of desktop GIS analysis to the next level.
• With the various forms of 3D data that are readily available - from free
government terrain models to custom collected LiDAR point clouds - there is a host of information waiting to be added to our everyday exposure to applied GIS.
• In recent years, Global Mapper has pushed towards making accessible
tools for advanced 3D analysis of any type of 3D data. Many industries are well suited to take advantage of these tools in everyday operations, from locating pad sites for construction, pipelines route planning, flood modeling, and many other common applications.
• This talk will cover some of the newer terrain analysis techniques
available in Global Mapper such as easily creating contours or elevation grids from raw data, elevation profiling, line of sight and view shed analysis, water shed modeling, transforming LiDAR into terrain models, and cut and fill volume calculations for excavation operations.

• “Data Mining” – extract value from old datasets once thought dormant • By taking advantage of free data and low cost software, powerful analyses
can be performed more easily than ever • 3d modeling of terrain and structures can save money and time by
evaluating potential construction sites for wind turbines, cellular towers, or other structures, without setting foot in the field until later in the process
• The data required in order to execute these processes is often freely
available • Leverage simple, freely available sources of data such as the National
Agricultural Imagery Program, and the National Elevation Dataset, to perform advanced terrain-based site analysis, with a minimum of investment and training
Leverage Existing Data
