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.

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

•

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)
