Global Mapper features dockable windows that support various data views, including top-down 2D, oblique 3D, and cross-sectional perspectives. These windows can be opened, resized, and arranged for the best possible display of different data types. In 3D data analysis, users can apply configurable color-ramp shaders to represent elevation or slope values in both 2D and dynamic 3D views. The 3D viewer also enables the creation of high-definition fly-through videos, allowing for an immersive visual presentation of point cloud, elevation, draped raster, and vector data in a format that’s easy to share.

Sharing data is versatile in Global Mapper, with support for various geospatial formats, screenshots, 3D data videos, and static map layouts optimized for PDF export or printing. The software’s layout tools facilitate the addition of cartographic elements like scale bars, compass roses, and legends, as well as supplementary text and branding graphics. These elements can be precisely positioned within the layout, and the entire design can be saved as a template for future projects. For atlas or map book projects, the map layout tool enables the creation of a tiled array of maps with a consistent layout across all pages.

Global Mapper also excels in exporting to web tile formats, generating web-ready raster tiles from current map data. These exports are compatible with popular online map formats like Google and Bing Maps and include an HTML file for displaying the tiles in the web interface of these formats, complete with standard map navigation and layout tools. Additionally, through a partnership with MangoMap, Global Mapper users can directly upload map data to a Mango-hosted online map site, facilitating easy sharing with clients, colleagues, or the public.

Global Mapper offers versatile support for displaying geospatial raster data, including layers that users have manually rectified within the software. It provides a range of tools for enhancing visual aspects of the data, such as creating multi-band data layers, pan sharpening, image tiling, and mosaicking. In addition to standard methods for adjusting image contrast, Global Mapper features histogram matching. This technique allows the colour channel histograms of one layer to influence the histogram adjustments of others, facilitating the seamless blending of data layers that may have been collected at different times or with varying equipment, thanks to additional tools for image feathering and contrast adjustments.

The software also enables the execution of mathematical operations on multi-band imagery or multiple data layers through raster calculation. It supports a variety of pre-built formulas for calculating indices like NDVI and NDWI, and allows users to create custom formulas using standard mathematical operations and more complex functions. For manual editing of raster layers, Global Mapper includes the Raster Reclassify tool. This tool enables users to transform pixel values within a layer based on specific rules they define, which are determined by designated input and output values.

Global Mapper’s dynamic terrain visualization is enhanced by tools that apply colorful shaders to both 2D and 3D data. This feature supports not only imported elevation data but also TIN layers created from 3D vector data. Users can generate cross-sectional profile views of terrain data from any linear feature on the map, whether existing or newly drawn. These profiles are useful for calculating elevation statistics and slopes along a path, and for conducting line-of-sight analyses to identify potential view obstructions. An innovative visualization option in Global Mapper merges these data views, allowing the Path Profile display to be shown as a terrain cutaway in the 3D View.

The software’s terrain data capabilities extend to various analysis tools that generate new vector feature layers, highlighting patterns or specific values within the terrain data. Users can create 3D contour lines in vector format from any imported or processed elevation layer. Contour analysis features include customizable interval spacing, polygon feature generation, and the identification of peaks and depressions in the terrain. Watershed delineation is another key feature, predicting the path of streams and their drainage areas. Building on the line-of-sight analysis from the profile view, viewshed calculations determine visible and hidden terrain areas from a specified point, considering factors like Fresnel Zone, signal strength loss over distance, and potential obstructions from 3D vector features.

Integrating vector features with terrain data in Global Mapper unlocks further analytical capabilities and data creation options. These include cut-and-fill volume calculations for both polygon and linear features, creating flattened site plans, and generating Relative Elevation Models (REMs). Cut and fill calculations can be applied to 2D or 3D vector polygons or along lines, simulating trench digging or creating flat terrain areas that blend seamlessly with the surroundings, ideal for simulating building sites. The REM feature is particularly useful for highlighting subtle terrain variations in a specific area, aiding in the visualization of minor terrain changes that might otherwise go unnoticed.

Global Mapper enhances its functionality with the capability to execute various tasks through scripting. Scripts, formatted as simple ASCII text files, are particularly useful for automating repetitive or routine tasks, thereby bypassing the need for manual data processing.
