Converts standard vector output (when in cylindrical mode) to give 0 to 360 degrees range rather than the default 0 to +/- 180. When using the calculator for vector addition as a navigational aid, negative course or heading results are unconventional. Pilots and helmsmen steer by 0 to 360 degree compass headings.
Contains a database with latitude, longitude, and elevation of over 1000 western US cities, plus it has the ability to calculate distance and approximate travel time between the cities.
Aerial photogrammetry flight map program to facilitate aerial mapping project estimation. All parameters can be altered for various Length and Width of project, Focal lengths, Photo scale, Forward and Side lap etc. 2 libraries included for both the 48GX and the 49G+. Documentation in PDF format (1 page w/attachments).
Helps do great circle navigation. Distances are in nautical miles. All programs provide a precision of better than 0.1'. If a vertex of the great circle is on the path traveled, provision is made for a "composite" (latitude limited) path, for example, to avoid icepacks or the Antarctic continent.
