- Convert ECI to ECEF Coordinates
- License: Freeware

Convert ECI (CIS, Epoch J2000.0) Coordinates to WGS 84 (CTS, ECEF) Coordinates. This function has been vectorized for speed. Example Function Call: >> [r_ECEF v_ECEF] = ECItoECEF(JD,r_ECI,v_ECI); Where: JD is the Julian Date vector [1 x N] (units are in days) r_ECI is the position vector [3 x N] (any units are permitted) v_ECI is the velocity vector [3 x N] (any units are permitted).

- Convert Cartesian (ECEF) Coordinates to lat, lon, alt
- License: Freeware

ECEF2LLA - convert earth-centered earth-fixed (ECEF) cartesian coordinates to latitude, longitude, and altitude. USAGE: [lat,lon,alt] = ecef2lla(x,y,z) lat = geodetic latitude (radians) lon = longitude (radians) alt = height above WGS84 ellipsoid (m) x = ECEF X-coordinate (m) y = ECEF Y-coordinate (m) z = ECEF Z-coordinate (m) Notes: This function assumes the WGS84 model. Latitude is customary geodetic (not geocentric). Michael Kleder, April 2006.

- Geo Photo Stamper
- License: Freeware

- Geo Photo Stamper will insert the date when a photo was taken as well as its GPS coordinates on your digital photos. - The application automatically reads all informations from picture files and adds them to bottom line of the pictures. - When you take a picture from your cell phone that navigation capability have, it saves GPS information. Geo Photo Stamper software reads this information and prints on your picture. - It's very easy to use, just select your picture folder and click on "Start". All pictures in your folders going to be stamped automatically. - Software is not printing information on pictures, instead, it adds a bottom line to picture.

- Minimum Enclosing Circle
- License: Freeware

This code takes an input of a set of given (x,y) points in the Cartesian coordinates and returns the center and radius of the minimum circle enclosing the points. This code is based on that of Yazan Ahed, and contains no changes in the algorithm but only in the structure. The previous code was written based on the very nice Java applet found here: http://heyoka.cs.uiuc.edu/~thite/mincircle/ Credit are due mainly to author of the applet..

- Nearest Neighbor algorithm for the Travelling Salesman Problem
- License: Freeware

The 2-column vector contains cities' coordinates. The algorithm generates the optimal path to visit all the cities exactly once, and return to the starting city. The algorithm has its limitations, and based on the cities' distribution on the map it may or may not give the optimal solution. It resolves the problem of the equally distant cities, that some other submitted files had..

- Curvilinear Coordinates
- License: Freeware

Programs and utility functions using the Symbolic Math Toolbox are provided to analyze vectors and tensors in general curvilinear coordinates. The programs perform the following functions: 1) runcoord plots intersecting coordinate surfaces for typical coordinate systems 2) runmetric computes and prints metric tensor properties a general curvilinear coordinate system 3) rundivcrl verifies agreement of numerical values of divergence and curl of an arbitrary vector computed in both cartesian and curvilinear coordinates 4) runconic plots surfaces illustrating how intersections of a cone and a plane produce conic section curves.

- xyz2rae
- License: Freeware

A variation of Matlab's cart2sph, that transforms a vector of Cartesian coordinates (East, North, Up) to radar coordinates (Range, Azimuth, Elevation). Note the different definition of radar coords vs. spherical coords, which require this different function (see exact definitions within the help comment). input format #1: [...] = xyz2rae(x,y,z) input format #2: [...] = xyz2rae(xyz) output format #1: [range, azimuth, elevation] = xyz2rae(...) output format #2: rae = xyz2rae(...) The input coordinates may be either singular values or a vector of coordinate points. Use the corresponding rae2xyz function for the reverse transformation.
