Global Mapper Overview
Equally well suited as a standalone spatial data management tool and as an integral component of an enterprise-wide GIS, Global Mapper is a must-have for anyone who works with maps or spatial data.
- Low-cost and easy-to-use GIS
- Supports more than 300 spatial data formats
- Optional LiDAR Module for powerful point cloud processing
- Advanced projection management using GeoCalc library*
- Unmatched technical support
*Requires current Geographic Calculator license
Global Mapper is more than just a utility; it offers a surprisingly extensive collection of analysis and data processing tools in a truly affordable package. Providing support for virtually every known spatial file format as well as direct access to common spatial databases, this remarkable application can read, write, and analyze all of your current data.
Global Mapper’s intuitive user interface and logical layout helps smooth the learning curve and ensures that users will be up-and-running in no time. Your company will quickly see a significant return on investment brought about by efficient data processing, accurate map creation and optimized spatial data management.
Terrain Analysis and 3D Data Processing
With a particular emphasis on terrain and 3D data processing, Global Mapper’s out-of-the-box analysis functions include view shed and line-of site modeling, watershed delineation, volume measurement and cut and fill optimization, raster calculation, customized gridding and terrain creation, contour generation, and much more.
Complementing these powerful analysis tools is a complete suite of raster and vector data creation and editing functions offering everything from simple and intuitive drawing to image rectification and vectorization.
Recent Developments in Global Mapper
For more than twenty years, Global Mapper’s development has depended on direct interaction with users and many of the major functional enhancements can be clearly traced to individual requests.
Version 20.1 – Enhanced Path Profile Tool
The importance of the Path Profile tool has grown immensely since the introduction of the LiDAR Module. New in version 20.1 is the option to zoom in the profile view for a more detailed view of a specific section of the profile line. The updated profile display also includes a legend option to more clearly define the individual surfaces when rendering profile lines for multiple layers.
Global Mapper 20.1 introduces a default projection option. With this new configuration setting, a specified projection will be automatically applied when creating or importing any new layer.
A new tool in the expansive suite of Digitizer functions will automatically remove gaps or overlapping areas between adjacent polygons. This simple edge-matching function is based on a defined distance threshold and ensures the topological integrity of the data.
Version 20.0 – Expanded Support for Working with 3D Models
Reflecting the ever-increasing importance of 3D data in the field of GIS, many of the functional enhancements in Global Mapper version 20 relate to the software’s 3D functionality. 3D Models or meshes can now be transformed into a point cloud which can subsequently be processing using Global Mapper’s extensive LiDAR editing and filtering tools. A new free-flight mode provides a 3D gaming-like perspective in the 3D Viewer.
Additional new functionality includes several new options in the Map Layout tool, expanded support for finger gestures when using a touchscreen computer, dramatic speed and performance improvements, especially when working with large vector files, and a new eyedropper tool for precisely selecting a color during various raster operations.
Version 20 also sees the introduction of a streamlined licensing process which integrates the activation of the software with a customer’s online user account. This new interface simplifies the procedure for verifying an order number or even requesting a temporary trial license.
Version 19.1 – New Querying Tool and Profile Line Exporting
The major functional enhancements introduced with the release of version 19.1 include a completely redesigned attribute querying tool offering multivariate attribute search options with advanced user-defined functions and expressions.; a new option to save and export 3D lines from the Path Profile tool; support for drag-and-drop docking of most floating windows including the Map Layout Editor, Coordinate Convertor, and 2D Map Views; an enhanced 3D Viewer, allowing the user more precise control over the process of zooming and panning; and consolidation of the advanced attribute management tools, such as Attribute Joining and Calculation, into the Attribute Editor Window.
Version 19.0 – Attribute Editor and Dynamic Hillshading
The most significant developments in version 19 include a powerful new attribute querying and editing tool. Replacing the former search function, the Attribute Editor is a spreadsheet-like display that allows real-time editing of feature attributes in a dockable window. Terrain visualization has been enhanced with an interactive tool for dynamically positioning the hillshading light source using real-time click and drag control. When displaying the 3D View, an option has been added to limit the geographic extent of terrain data displayed based on the visible extent of the 2D map, which significantly improves the rendering speed.
Additional improvements in the version 19 release include an expanded list of built-in online data sources, which now includes streaming services form individual U.S. states and Canadian provinces (when available). The process of docking windows has been streamlined with drag and drop positioning for all dockable windows, including the 3D Viewer, Path Profile and Attribute Editor. Raster calculation now offers several new built-in functions including Normalized Difference Snow Index (NDSI) and Advanced Vegetation Index (AVI).
Version 18 – Redesigned and Improved Interface
Version 18 introduced a complete redesign of the interface along with a fresh new logo and updated button graphics. The toolbars were reorganized to promote more efficient access to critical functionality and each toolbar can be customized by adding or removing buttons to reflect the requirements of each user. A dockable multiview map display was also added allowing simultaneous side-by-side views of a particular geographic area at different zoom levels or using different datasets.
