2013 Vendor Track, LiDAR Processing and Terrain Analysis in Global Mapper by Adam Hill

Adding the third dimension to a mapping project can take the power of desktop GIS analysis to the next level. In recent years, high-resolution elevation data has become increasingly available, resulting in more precise analytical tools. Much of this trend can be attributed to the expanded availability of LiDAR data and the development of inexpensive software tools that can process and utilize this data. In this presentation we will consider one such application, Blue Marble Geographics’ Global Mapper software, which can work with over 200 spatial file formats, including LiDAR (.las and .laz), and offers an array of tools for generating terrain surfaces, 3D modeling, and terrain analysis. In this presentation, we will explore LiDAR processing functionality of Global Mapper including point cloud visualization, data quality control and reclassification, volumetric calculation, contour generation, linear profiling, watershed delineation, view shed modeling, as well as terrain flattening and cut & fill volume calculation for site planning.

2013 Vendor Track, LiDAR Processing and Terrain Analysis in Global Mapper by Adam Hill

  1. 1. Terrain Analysis in Global Mapper GIS in the Rockies, Oct 2013 Adam Hill Senior Account Manager adam@bluemarblegeo.com www.bluemarblegeo.com Copyright 2010 Blue Marble Geographics
  2. 2. Terrain Analysis in Global Mapper • 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.

  3. 3. Leverage Existing Data • “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 Copyright 2010 Blue Marble Geographics
