Global Mapper is a powerful Windows application built specifically for helping you manipulate GIS (geographic information system) data in a professional way.
The user interface may seem a bit overwhelming at a first glance, but this is only because the application comes packed with many dedicated parameters. In order to make the most out of every single built-in feature, you should check the online help manual and useful tutorials.
Global Mapper offers support for a wide range of data formats: GeoPDF, DLG, DRG, DOQ, DEM, DGN, DTED, DWG, DXF, GPX, SDTS DEM, ECW, GRD, JPEG, CADRG/CIB, KML/KMZ, and others.
As soon as you run the application, the program puts at your disposal four main operations, namely open your own data file, download free maps or images from online sources, configure the program settings, or load sample data.
Global Mapper enables users to zoom in or out of the map, activate the 3D mode, pick the background colour, draw and measure segments and areas, select the vector features (areas, lines, and points), view loaded elevation datasets and perform line of sight calculations, and use a built-in coordinate convertor.
Furthermore, there are several tools designed to help you create an elevation grid from 3D vector data, combine or compare terrain layers, generate contours and watershed, find ridge lines, and measure volume between surfaces.
The search process can be carried out in terms of name, attributes, and description. Plus, you can perform search and replace operations and look for addresses.
Other important features worth mentioning allow users to activate the GPS function, pick the colour, size, and shape of the vessel, mark the waypoints, as well as select new areas on the map and modify their features in terms of type (e.g. sands, watersheds, wooded area, lakes, islands, reservations), name, and distance.
The generated data can be exported to a multitude of file formats, namely PDF, JPG, PCX, PNG, RAW, KML/KMZ, DXF, SVG, and others.
All things considered, Global Mapper is a reliable application that bundles many useful features for helping you manage GIS data efficiently. It is suitable especially for advanced users because it provides a wide array of tools.
