You can also edit existing vector features. Newly created and editing features can be saved to any of the supported export formats. In addition, shapes like rectangles, circles, ellipses, arcs, and concentric range rings. can be easily drawn as well. You can track a compatible GPS device connected to your computer’s serial port or USB port in real-time over any loaded data. In addition, you can mark waypoints at the current GPS location and record a tracklog of where your GPS device has been while connected, all seamless with your loaded map data! – Global Mapper supports accurate conversions between a large list of projection systems and datums. NAD27 datum conversions in the US use the NADCON conversion method, and the NTv2 datum conversion method is used for the NAD27 (Canada), AGD66, AGD84, and NZGD49 datums. Custom datum conversions can be easily added in either 3-parameter or 7-parameter form if a required datum transformation is not already supported. You can export both vector, raster, and elevation data to a variety of formats (see below). You can merge any combination of data sets, regardless of source scale, type, and projection. You can also breakup your data into a regularly spaced grid on export if you’d like as well. Here is a partial list of supported export types. You can graphically rectify (georeference) any JPG, TIFF, or PNG image and save the results to a new fully georeferenced image. Vector data can also have a rectification process applied to it after loading to allow morphing vector data to fit other data sets. You can create contours for any combination of elevation data. You can also specify the contour interval to use. The generated contour data can then be exported to any of the supported vector export formats (see previous item for a list). , such as ASCII XYZ files. This allows you to convert a set of elevation samples into a fully gridded data set, which can then be used for contour generation, line of sight analysis, and view shed analysis, among other things. The data can also be exported to any of the supported elevation grid formats, such as USGS DEM. Advanced screen capture. You can capture the contents of the screen to a BMP, JPG, PNG, or (Geo)TIFF file of user-specified resolution. . You can now have the collar of USGS DRG files automatically clipped off. This allows you to seamlessly view a collection of adjacent DRG files. Supports opening SDTS DLG, SDTS DEM, and most other file types directly from .tar.gz and .zip archives. This saves the major headache of decompressing each SDTS transfer into a separate directory. , including multi-segment path lengths and headings, enclosed area, and cut-and-fill volume calculations either along a path or within an enclosed area. Supports opening DLG-O and DEM files directly from gzipped archives. This means that you can save space and hassle by not having to decompress the data after you download it. Slide over text. When you move your cursor around the screen you’ll get a description of the nearest feature automatically displayed in the status bar. Source.
