Designed to work with imagery, palette, and elevation raster data, reclassification rule sets can be saved to use with multiple datasets for uniform reclassification.Ī commonly used raster enhancement process, pan sharpening uses a higher resolution panchromatic band of satellite collected data to increase the resolution of RGB imagery. Users can use predefined 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 two values.įor the manual reclassification of any pixel-based data, the Raster Reclassify tool in Global Mapper assigns new values to pixels in a dataset based on user input rules defined by input and output values.

This process aids the blending of data layers collected at different times or with different equipment.Īllowing mathematical operations on multi-band imagery to extract different types of information, the Raster Calculator is found under the Analysis menu. Global Mapper supports flexible raster data display, including contrast adjustment, support for multi-band data, pan sharpening, image tiling, and mosaicking with no need for additional modules.Īdding to the contrast adjustment options available for raster image data is Histogram Matching, which allows the color channel histograms of one layer to dictate the histogram adjustment in others. 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 With new and modified formats being added on an ongoing basis, you can be sure that the software will never be out of date with your data.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.
