DIGITIZING SUPPORT! You can digitize new vector (area, line, and point) features by drawing them with the mouse. 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, buffers around existing features, and concentric range rings can be easily created as well. You can also input features via a series of distance/bearing/COGO coordinates.

GPS SUPPORT! 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! With supported devices (such as the RavTrack GPS Transponders from RaveonTech) you can even track multiple GPS devices in order to perform fleet management functions. You can also send any loaded data to comaptible Garmin GPS devices (like Oregon and Colorado devices), thus allowing you to easily view imagery and other data on your handheld Garmin device.

PROJECTION/DATUM SUPPORT - Global Mapper supports accurate conversions between a large list of projection systems and datums. NAD27 and NAD83 HPGN/HARN 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.
