Global Mapper Is Used
Overview
Global Mapper® is a cutting-edge GIS application developed by Blue Marble Geographics of Hallowell, Maine. It provides both novice and experienced geospatial professionals with a comprehensive array of spatial data processing tools and access to an unparalleled variety of data formats. An intuitive user interface and logical layout smooth the learning curve so that users are up-and-running in a matter of days, while the underlying engine handles multi-gigabyte imagery mosaics, elevation grids, and LiDAR point clouds on ordinary desktop hardware.
Organizations of any size see a rapid return on investment through efficient data processing, accurate map creation, and optimized spatial data management. Global Mapper is offered as a single affordable license — with the Global Mapper Pro extension adding advanced LiDAR classification, feature extraction, terrain painting, and Pixels-to-Points photogrammetry — and version 27 embeds Blue Marble's GeoCalc geodetic library directly into the application, eliminating the need for separate coordinate transformation tools and bringing survey-grade geodetic accuracy into every workflow.
Key Features & Global Mapper Capabilities
Over 300 vector, raster, elevation, and point cloud formats are supported natively — no add-ons or additional licenses required. Users can load, combine, crop, reproject, and tile virtually any data they encounter, and new or modified formats are added continuously so the software never falls behind the data being produced.
Global Mapper streams a vast library of built-in online sources directly into the workspace: worldwide aerial and satellite imagery, global elevation datasets, topographic maps, Landsat scenes, land cover, and aviation charts — providing instant geographic context without downloading or preparing basemap data manually.
Flexible visualization of 2D and 3D data with customizable shaders, draped imagery, and animation creation. The 3D viewer records HD fly-through videos of point clouds, terrain, and draped rasters, while the layout tools produce print-ready map sheets, PDF exports, and web tile output for sharing results.
A complete digitizing toolkit for point, line, and polygon creation, plus specialized geometric tools for range rings, grids, and buffers. The Spatial Operations tool performs Intersection, Union, Difference, and Symmetrical Difference along with spatial predicates and transformations for complex multi-layer comparisons.
Multi-band layer creation, pan sharpening, tiling, mosaicing, image feathering, contrast adjustment, and histogram matching blend datasets captured at different times or with different sensors. Raster calculation supports NDVI, NDWI, NBR, other common indices, and custom formulas, while Raster Reclassify converts pixel values by rule.
Dynamic terrain visualization from imported elevation data and TIN surfaces generated from 3D vectors. Generate contours with custom intervals, identify peaks and depressions, and run watershed delineation, view shed and line-of-sight analysis, cut-and-fill volume calculation, and cross-sectional profiling directly on the terrain.
Load, filter, and classify massive LiDAR datasets with automatic ground, building, powerline, and vegetation classification, noise removal, thinning, and point cloud registration. Extract features, generate breaklines and terrain models, and reconstruct 3D buildings — with the most advanced tools available in the Global Mapper Pro extension.
The Global Mapper scripting language and batch conversion tools automate repetitive processing across thousands of files, and the Python SDK opens the engine to custom development. With Blue Marble's GeoCalc geodetic library now integrated, coordinate system transformations and geodetic accuracy are handled inside Global Mapper without separate tools.
Global Mapper Platform Overview
An overview of Global Mapper — how Blue Marble Geographics' all-in-one GIS application handles data import, terrain and LiDAR analysis, map production, and automation in a single desktop environment.
Deep Dive: LiDAR, Terrain & Geodetic Processing
The defining strength of Global Mapper is breadth without fragmentation: data translation, terrain modeling, LiDAR classification, photogrammetry, geodetic transformation, cartography, and automation all live inside one application and one license. Workflows that normally cross three or four specialized products are completed end to end, with the same coordinate handling and the same interface at every step.
Point Cloud Classification & Feature Extraction
Global Mapper Pro applies automated classification to raw LiDAR returns — separating ground, vegetation, buildings, powerlines, and poles — then extracts vectorized features from the classified cloud. Building footprints and 3D models, powerline catenaries, tree points with height and crown metrics, and stockpile volumes are derived directly from the point data, replacing hours of manual digitizing with repeatable, parameter-driven processing.
Terrain Modeling & Hydrologic Analysis
Elevation grids and TIN surfaces built inside Global Mapper support the full range of terrain analytics: slope, aspect and curvature rasters, contour generation, watershed and stream network delineation, flow accumulation, and flood-fill modeling. Cut-and-fill volume calculation and terrain painting allow engineers to design and quantify grading scenarios against measured survey data in a single environment.
Geodetic Accuracy with GeoCalc
Blue Marble's GeoCalc geodetic engine — the same library licensed by GIS and CAD vendors worldwide — is embedded in Global Mapper. It provides thousands of datums, projections, geoid models, and grid-based transformations, along with time-dependent and plate-motion aware transformations, so data captured in different reference frames aligns to survey-grade tolerances without exporting to an external coordinate conversion tool.
Drone & UAV Photogrammetry Workflows
The Pixels-to-Points tool turns overlapping drone imagery into dense point clouds, orthoimages, and 3D meshes entirely within Global Mapper. Combined with GPS-tagged photo import, image rectification, and terrain generation, survey teams move from a completed flight to a measurable deliverable in the same software they use for mapping — no separate photogrammetry suite or cloud processing subscription required.
Batch Processing & Workflow Automation
Global Mapper scripts chain together loading, reprojection, clipping, analysis, and export operations that run unattended across entire data directories. Scheduled scripts, batch format conversion, and the Global Mapper Python SDK let organizations standardize deliverables, enforce coordinate system policy, and process recurring datasets at a fraction of the manual effort.
Field Data Capture with Global Mapper Mobile
Global Mapper Mobile extends the desktop workspace to iOS and Android devices. Prepared map packages — including imagery, terrain, and editable vector layers — are taken offline into the field, where crews collect attributes, photos, and GPS positions. Completed packages sync back to the desktop, closing the loop between office analysis and field verification without third-party data collection platforms.
