GIS in the Rockies, Oct 2013

• 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.

Terrain Analysis in Global Mapper

• “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

Leveraging LiDAR for Terrain Analysis

• Free data sources available

• Leverage existing data already collected

• Many times data collection will involve the capture of many different types of data (ie. Imagery, lidar, etc)

• Global Mapper removes barriers to data access and allows users to build new data with existing data

• Extract a greater return on investment from your data

Know Your Data

• LiDAR is widely available • Many freely available datasets can be leveraged for rich content extraction & analysis • DEM – Digital Elevation Model

• If you have elevation data, you have gold •Generate Contours • Line of Sight Calculations • Viewshed Analysis, Watershed Analysis • Global Mapper allows for flexible analysis and offers a variety of features for creating your very own GIS data

• Manual Classification through Digitizer Tool

• Auto-classification is coming soon

• A multitude of options provided now when loading in LiDAR data

• New features built from direct customer feedback, industry events, lidar hardware companies

• Companies aren’t just flying LiDAR, they’re collecting a variety of data types (ie. Imagery)
