Terrain Analysis

Global Mapper provides a number of tools for modifying and analyzing terrain data. There are also tools for calculating information from terrain data based on vector features, and creating vector features from terrain data.

Analysis methods for this type of data can also be applied to other raster data that contains values representing a measurement or phenomenon other than elevation, such as temperature, etc.

Some of the available analysis options include:

• Create Elevation Grid from 3D Vector Data
• Combine/ Compare Terrain Layers
• Count Overlapping Raster/Terrain/View Shed Layers
• Find Overlap Between Lidar/Raster/Terrain Layers
• Create Curvature Grid from Terrain Layer(s)
• Generate Breaklines from Terrain Grid
• Create Contours (from Terrain Grid or Lidar)
• Find Ridge Lines
• Measure Volume Between Surfaces
• Create Watershed
• Simulate Water Level Rise/ Flooding
• Raster Calculator
• Generating a 3D Path Profile from a Selected Line or Area Feature
• Calculating Cut-and-Fill Volumes for Area and Line Features
• VOLUME - Measure Volume (Cut and Fill)
• PILE VOLUMES - Calculate the Volume of Selected Piles
• Calculate Elevation / Slope Statistics for Selected Features
• Create Viewshed
• Create Area Features from Equal Values
• Create Point Features at Elevation Grid Cell Centers
• Find Extreme (Min/Max) Elevation Values
• Path Profile
• Terrain Painting
