The viewshed analysis determines the coverage in all directions within a specified radius from the signal source. Similar to the line of sight calculation, the viewshed analysis tool is typically used to determine the area covered, or not covered, from a broadcast site with a specified transmitter height. A visualization option allows the Path Profile display to be rendered as a terrain cutaway in the 3D View. This is especially useful for the analysis of a radio or broadcast signal. Additionally, line of sight calculation can be used to visualize any obstructions that may interfere with the view along the profile path. These profiles can be used to calculate a variety of statistics related to the elevation and slope along the path. These functions are included as part of the standard installation and require no additional extensions or plug-in components.Īny line feature on the map can be profiled to create a cross-sectional view of the underlying terrain. Global Mapper includes several powerful terrain analysis tools that are used to process or model elevation data. Combined with scripting and batching tools, it has the capability to automate many GIS processing tasks.

Global Mapper has full attribute and geometry editing capabilities rivaling any other GIS software on the market today. Complex vector layer comparisons and feature creation can be performed with the Spatial Operations tool, which features Intersection, Union, Difference, and Symmetrical Difference operations, along with numerous spatial predicates and transforms.
Modifications can be applied to entire features or to individual vertices that determine the shape and size of a feature. Advanced coordinate geometry input can be employed to create objects on the map by simply typing the geometric dimensions of each segment.Įditing functions include rotating, scaling, and moving 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. If you are interested or in need of OTF support, please contact additional information.Īs well as offering unrivaled access to pre-existing spatial datasets, Global Mapper provides a vast array of digitizing tools for creating and/or editing features on the map. This terrain is acted upon by other environmental services to provide information to the simulation models to help them determine movement ability, speed, acquisition, and other capabilities needed to support the simulation activities and requirements. The OTF integrates features and elevations into a single-layered, polygon-based representation using Irregular Triangulated Integrated Network (ITIN). OTF data can be created via GOTS (Government off-the-shelf) and COTS (Commercial off-the-shelf) toolsets and from traditional GIS datasets, as supported within the toolsets. This file format contains four types of files, a database header file (.dhf), an OTF file (.otf), three network database files (.nw), and a single elevation map file (elevation_map). The Objective Terrain Format (OTF) is the runtime representation of the synthetic natural environment (SNE) for the US Army’s One Semi-Automated Forces (OneSAF) simulation software. Global Mapper’s OTF Reader Module is used by military personnel for mapping simulation exercises. The new wireless direct data transfer capability allows the easy sharing of data, file exports, and feature templates from the desktop version of Global Mapper to Global Mapper Mobile, a mobile app, available on iOS and Android, for taking data into the field for reference and GPS-enabled data collection During export, data can be tiled 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. Vector, raster, and elevation data can be exported in virtually every common file format as well as many proprietary types. 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. Offering direct access to over 300 raster, vector, and elevation data types, Global Mapper supports virtually all types of geospatial data right out of the box, no add-ons required. One of the unique and defining characteristics of Global Mapper is its extensive and varied data format support.
