This calculates the midpoint between two GPS coordinates along the Earth's surface.
Based on formula from http://www.movable-type.co.uk/scripts/latlong.html
A collection of utilities for translating GPS coordinates to related coordinate systems (Earth Centere Fixed, Topocentric, UTM) with auxiliary routins for horizon computation and ray ellipsoid intercepts.
Designed to collect fisheries data linked to GPS coordinates from small fixed wing aircraft. SQL database runs on WinCE, Palm PDA & other platforms. Program was written using SuperWaba: a robust java-like development environment for...
These files help to map a set of points to a set of edges and arcs.
This maybe interesting for matching GPS coordinates to infrastructure plans.
The simple algorithme was taken from

With this plugin you can have Instant GPS Tracking for your WordPress site. (Extended version of GEOTAG plugin.). You can add coordinates to your posts and display maps with these positions. On these maps you can also display KML/KMZ files or the...
The Whereis module is a proof of concept that allows you to send coordinates from your GPS-enabled phone to Drupal. At the moment this module doesn't do much except update a location-enabled node with a new latitude and longitude.
This code outputs the distance between 2 GPS points showing also the vertical and horizontal bearing between them. This code was originally made for an Automatic Tracking Antenna Aimer. If you find it useful please take note of the owner. If you...
Window Coordinates code creates a window (with the Win32 API) and displays the coordinates of the windows client area in pixels in the form of X-Axis, Y-Axis.
The window can be moved, and the coordinates will be re-displayed with the...
MATLAB implementation of IGRF11 fortran code as function for calculating Earth mean magnetic field. Implementation has been modified to default to GPS reference coordinates with output B components North, East, and Vertical. Spherical harmonic...
ECEF2LLA - convert earth-centered earth-fixed (ECEF) cartesian coordinates to latitude, longitude, and altitude.
[lat,lon,alt] = ecef2lla(x,y,z)
lat = geodetic latitude (radians)
lon = longitude (radians)
[alpha,delta] = eclip2equat(lambda,beta) returns the right ascension and declination in the equatorial coordinate system corresponding to the longitudinal and latitudinal coordinates in the ecliptic coordinate system (lambda and beta).
This function returns the coordinates for a 2-D spring, with the possibility of adding offsets at the two ends.
The spring is automatically sized using the maximum expected length and the number of coils.

Convert WGS 84 (CTS, ECEF) Coordinates to ECI (CIS, Epoch J2000.0) Coordinates. This function has been vectorized for speed. The associated error in converting between coordinate frames is on the order of 1.2*10^-11 km when compared to STK...
The most outstanding feature is the high modularity of the components that enable integration of GPS-receivers into own software products. Most commmon receivers (NMEA, Garmin, Trimble) are supported out-of-the-box but you can easily extend the...
Plug in three coordinates to triArea(a,b,c), and it will return the area of the triangle.
some common variable letters transfer into these meanings:
y,c: y intercept
a: x's coefficient
b: y's coefficient
Calculates the checksum of an NMEA sentence (GPS data).

dat2dxf is a small command line tool to convert the Selig xy formated airfoil coordinates to dxf output tool to t;
This code takes an expression for a normalized AF in spherical coordinates and creates a 3D plot in cartesian coordinates. Examples are specific to Antenna Theory and Design (2nd Ed) by Stutzman and Thiele.
