GeographicLib is a small C++ library for: geodesic and rhumb line calculations; conversions between geographic, UTM, UPS, MGRS, geocentric, and local cartesian coordinates; gravity (e.g., EGM2008) and geomagnetic field (e.g., WMM2020) calculations.

A small server-side application is dedicated to provide TCP-packets response and basic logging functionality from operating low cost commercially available GPS Vehicle Trackers such as Concox GT06N and perhaps others (GT06E and GT06F). The application is using POSIX API and intended to run on Unix, Linux and even Windows systems (cygwin environment). Currently it has been developed and tested on FreeBSD 14.3. Recently added limited support for VL103 series devices from Jimi IoT Co., Ltd..

Mkmap is a map maker by downloading map tiles from online map services, like google maps, and combining into a single large picture file. It accepts the latitude and longitude coordinates, then downloads and merges map tiles. The idea of mkmap is to generate a larger map than the size of a browser screen. So the map could be easily printed or viewed in an off-line device. Mkmap supports Linux and Windows platform.

Technique, C-subroutine, and starter applications for transforming cylindrical coordinates to pixel coordinates where wrap-around and edge clipping are handled seamlessly.
