The new multi-view map display in Global Mapper™ allows several docked map windows to be displayed within the interface for better data visualization and manipulation. These views, which support both top-down 2D rendering as well as oblique 3D viewing, can be independently zoomed and panned and can be resized to make the most efficient use of the available screen space.
These allow 3rd-parties and customers to create add-ins to Global Mapper to extend the functionality through their own toolbars and/or menu items. The feature extensions will have access to all data loaded in the Global Mapper application instance through the same API used by the Global Mapper SDK. There is an item under the Help menu for managing the installation and registration of feature extension plugins and add-in modules. For more information on how to write and publish an extension contact your Blue Marble sales representative (firstname.lastname@example.org)
Global Mapper works as easily with 3D data as it does 2D data. It supports many types of 3D data including elevation or terrain models as well as 3D mesh formats such as 3D PDF, Collada, Wavefront, 3DS Max and more. These model formats can be transformed in to a 3D point cloud, which can subsequently be edited and filtered using the extensive LiDAR processing tools. The software includes a powerful 3D Viewer which can be docked and linked to the 2D map 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.
Global Mapper's 3D functionality includes support for setting up and recording HD 3D fly-through videos of your 3D projects. Additional fly-through features include a setting for UAV or Aerial tracking playback to display a video file synced to any line feature with per-vertex times. Support has been added for features such as draping vector data, GPS tracking and Skyboxes for rendering a sky simulation in 3D. Support has also been added for 3D textures and meshes in GMP files. When recording a fly-through video file, the video file will automatically be associated with the fly-through feature so you can easily play it back from the Feature Info or Digitizer Tool.
There is now a new 3D navigational aid, the pivot axis, which shows the scene rotation pivot location. This may be toggled on or off using the 3D right-click context menu or by using the Ctrl+Shift+P hotkey.
One of the unique and defining characteristics of Global Mapper is its extensive and varied data format support. Offering direct access to over 250 different raster, vector, and elevation data types, including 3D PDF files, Global Mapper supports virtually all types of geospatial data right out of the box, no add-ons required. With new and modified formats being added on an ongoing basis, you can be sure that the software will never be out of date with your data.
The list of export formats available within Global Mapper is as impressive as the supported data import types. Vector, raster, and elevation data can be exported in virtually every common file format as well as many proprietary types. During export, data can be gridded into smaller or more manageable files or the export area can be cropped to a defined area or to the extent of the current screen view. The latest version dramatically sped up raster/elevation exports cropped to complex area features. For very complex areas (i.e. hundreds or thousands of vertices) the exports may be 10x as fast or even better!
Import and export data from your spatial databases. Global Mapper includes support for the following spatial databases:
View and process point files with a billion points or more. A dramatic increase in LiDAR processing and display speed is beneficial for previewing the data before creating a gridded surface model and includes several options for filtering the data during import and for rendering the point cloud to reflect return type or intensity. Metadata access provides a detailed statistical breakdown of the point cloud and customizable point size improves on-screen display. Global Mapper Package (.GMP) files are able to store LiDAR point clouds in a special compressed format, much smaller than uncompressed LAS data and on par with the best compression available today. This allows LiDAR data to be efficiently archived or shared with other Global Mapper users. The latest version of Global Mapper includes searching by elevations, a point loading slider bar, reporting tools for point cloud density and improved import and export options including point cloud to DXF/DWG. For those interested in adding more advance LiDAR processing functions, faster gridding and powerful path profile editing the Global Mapper LiDAR Module is an additional optional purchase that is still a very affordable price compared to equivalent technology.
With many data GIS administrators choosing to distribute data through web-based services instead of offering file downloads or disk media, there is now a vast quantity of readily available spatial data just a mouse click away. Global Mapper's online data function includes direct links to many of these data services including one-meter aerial imagery for the U.S., worldwide elevation data, topographic maps, Landsat satellite imagery, land cover data, the full Maine GIS catalog, aviation charts, OpenStreetMap vector data via WMS, and much more. Furthermore, if a local agency or organization develops a Web Mapping Service, a custom link to this data can be easily added to the online data source list. These web-based datasets can be either streamed in real time or exported to a local file for offline use.
Through agreements with commercial data vendors, Global Mapper also offers fee-based access to premium spatial datasets. Using the Online Data function, you can download high-resolution imagery from DigitalGlobe, elevation data from Intermap, or US Land Parcel Data from Corelogic.
Accessing these online data sources from Global Mapper is easy, simply go to the File menu and select Download Online Imagery/Topo/Terrain Maps.... A customizable list of sources will be displayed.
Global Mapper has built in support for importing and exporting data in Google's KML/KMZ format. The software has an extremely powerful export menu guiding the user with a flexible selection interface for everything from translucency to feature descriptions to encoding of zip files. Users can display labels or not, highlight cursors, manipulate export of 3D feature types, and much more including tiling options. Global Mapper also publishes to Google web map tiles and KML/KMZ web map export for creating your own online Google maps interface. There is also a handy feature short cut for displaying your data on Google Earth right within the map window.
A standard function of Global Mapper is its ability to import virtually any image file and to create a geographically aligned and scaled raster layer. The Image rectification process supports the manual input of image pixel and corresponding ground control coordinates, or the simple tagging of recognizable points on the image as well as the corresponding locations on a base map layer. Advanced options allow the selection of the rectification method, resampling scheme, and ground control projection parameters.
The resulting raster layer can be analyzed and processed just like any other imported layer and can be exported in any one of the supported raster formats.
Global Mapper includes a powerful geocoding function that allows real-world coordinates to be assigned to an imported database of addresses. The geocoding process can use either a preconfigured online service or a user-imported road network to accurately determine the point that represents the location of each address. If necessary, this data, including the coordinate values, can be exported in tabular form or plotted on the map to provide a visual perspective.
The Graph and Chart Manager allows the user to create graphs and charts from loaded data. The following type of operations are supported:
As well as offering unrivaled access to preexisting spatial datasets, Global Mapper provides a vast array of digitizing tools for creating and/or editing features on the map. As well as the standard point, line and area creating functions, there are also tools for creating specialized geometric features such as range rings, grids, and buffer areas. Advanced coordinate geometry input can be employed to create objects on the map by simply typing the geometric dimensions of each segment.
Editing functions include rotating, scaling, and moving features on the map. Modifications can be applied to entire features or to individual vertices that determine the shape and size of a feature. Global Mapper has full attribute and geometry editing capabilities rivaling any other GIS software on the market today. Combined with scripting and batching tools it has the capability to automate all of your GIS processing data needs today.
Global Mapper offers limitless possibilities for assigning specific visual characteristics to vector features on the map. Preinstalled or custom symbols can be attributed to points; multiple line styles and weights can be applied to linear features; and solid or patterned fill shading can be assigned to area features. The appearance of features in Global Mapper is usually controlled by the style that has been established for each feature type but the style can also reflect an attribute of the data allowing for the creation of thematic maps.
Automation for feature creation includes the ability to create a series of features that share the same attribute structure, target layer, and other characteristics without having to repeatedly confirm these settings in the Modify Feature Info dialog box.
Many functions in Global Mapper can be performed by initiating a script. Formatted as a simple ASCII file, a script is commonly used to automate repeating or recurring tasks, eliminating the need to manually process your data. Scripting language supports importing, converting, reprojecting, analyzing, calculating attributes, splitting layers, interactively prompting users for files and folders and exporting all supported data formats. Powerful scripts can be created including conditional processing within the script (IF/THEN/ELSE). The scripts can either be run from within Global Mapper or as a standalone process. Support has been added for passing variables on the command line to a script. Users can provide the variable after the script (.gms) filename itself on the command line in the form '-var_name var_value'. For example,

Global Mapper includes several powerful terrain analysis tools that allow you to process or model elevation data. These functions are included as part of the standard installation and require no additional extensions or plug-in components.
Global Mapper includes numerous functions for processing imported data.
Global Mapper contains a full featured dedicated menu for GPS data management. With a compatible GPS receiver attached to your computer, you can track your location in real time superimposed on any available map or data layer. With the advanced 3D viewer you can then create HD fly-through videos from your GPS data. In the 2D viewer you can also use your GPS heading to automatically rotate the map view any way you need it. Additionally you can create waypoints from your current location or record a track log to delineate your movement and much more.
When it comes time to share your maps or data, Global Mapper offers many output choices.
The Raster Calculator found under the Analysis menu can be used for performing mathematical operations on multi-band imagery to extract different types of information. Users can use pre-defined formulas, like NDVI and NDWI, or create their own free-hand formulas using common mathematical operations, like addition, subtraction, multiplication, division, and powers, as well as simple operators like absolute value, minimum value, and maximum value of 2 values.
