Global Mapper works as easily with 3D data as it does 2D data. It supports several 3D formats such as 3D PDF, Collada, Wavefront, 3DS Max and more. The user has the ability to link the 2D and 3D viewer so panning, zooming, and adding vector features will automatically replicate in both windows. This powerful functionality also includes the ability to select and measure features in the 3D viewer. These tools are initiated by selecting the Digitizer tool or Measure tool on the 3D viewer toolbar. Any selections are shared by both the 2D and 3D viewer, and the right-click menu allows you to perform many Digitizer operations on the selection.
