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,...
Calculates: Azimuth, Elevation Angle, Slant range, Coverage Angle/Area
Skalli is a simple tool to estimate the IVS reference point of an azimuth-elevation type VLBI radio telescope.
Calculates azimuth and elevation angle in the local horizon system for a sky position given in equatorial coordinates (RA Dec J2000).
Function Call: [Az El] = RADec2AzEl(350,58, '2008/02/18 13:10:00',60,15,0)
PlotSphereIntensity(azimuth, elevation, intensity)
h = PlotSphereIntensity(...)
Plots the intensity (as color) of a number of points on a unit sphere.
GUI to calculate and visualize the radiation pattern of ultrasound transducers.

Predict the azimuth and elevation of the Sun within +/- 1 degree at any geodetic latitude, longitude and altitude.
Function Call: [Az El] = SolarAzEl('2008/02/18 13:10:00',60,15,0)

-calculation of satellite angles: elevation, azimuth, and also relative azimuth and baseline orientation if input data
-belongs to two sites
Based on the Two line elements(TLE) - Input from the user, the program calculates the time and the date of the satellite pass. Prints out Azimuth and Elevation & plots it too.
RaDec2AzEl will take the Right Ascension and Declination in the topocentric reference frame, site latitude and longitude as well as a time in GMT and output the Azimuth and Elevation in the local horizon reference frame.
Convert Right Ascension/Declination angles in degrees to Altitude/Azimuth in degrees for an Alt/Az telescope mount.
Input: RA - Right Ascension in degrees
Dec - Declination in degrees
Latidute - Observer's Latitude (Negative for...
Have sleepless nights trying to get Vista's UAC under control. This COM Object (supplied both as a compiled DLL and with fulll BDS 2006 source) handles all the common tasks that require elevation under Vista, e.g. writing to registry,...
The actual version requires the following MATLAB toolboxes:
- Mapping toolbox (for elevation())
- Image Processing Toolbox (for imshow())
A providing of toolbox independent functions would be greatly acknowledged.
Using this script, you can generate a set of data regarding Sun Azimuth Positions at various instants of time for any location on Earth. This data can be used in many applications, like, in determination of orientation of any plane's azimuth from...
A collection of functions for calculating the upslope area and related measurements for a digital elevation model (DEM).
Based on the method of Tarboton.

ELEV = GETELEVATIONANGLE(GR,H1,H2,REFFECTIVE) Determines the elevation
angle of a target based on ground range (GR), altitude of the observer
(H1) and the altitude of the target (H2), and the effective radius of
Spherium allows for the creation of a cornicopia of curious 3D objects and offers full interactive control over lighting and orientation.
Spherium contains a function (fig2pic) which can construct very high resolution images of any...
This function provides continuous rotation of a 3D figure on the mouse up click. This may prevent a little bit of RSI ;-) It displays the elevation and azimuth values while rotating. Rotation is in the direction of mouse movement away from the...
</b>In 1975, Vincenty published a rapidly converging algorithm for computing the distance between points on an ellipsoidal earth. The algorithm is precise to within a few millimeters. Since then, his algorithm has since seen significant...
A simple Perl script to conver AAIGrid (Arc/Info ASCII Grid) digital elevation model data into a TGA image suitable for POVray's height_field object.
