# Conversion of UTM Coordinates to Spherical Coordinates

02 Aug 2005 (Updated 05 Sep 2006)

Little GUI allows you convert UTM coordinates to spherical coordinates.

File Information
Description

0. Syntax:[long,lonm,lons,latg,latm,lats,Direction] = UTMIP(instruccion)

1. With this little routine, you can get the transformation or the conversion of UTM coordinates to spherical coordinates, you can choose different ellipsoids to execute the conversion.

2. Inputs:
x, y, utm zone, and hemisphere.

3. Outputs:
Latitude, Longitude and the reference of the Longitude.

4. Notes:
It's only necessary to run the function.
I designed the window in order to display in a screen of 1024 x 768.
This is the "inverse problem" of Spherical coordinates to UTM coordinates. You can also see the routine:

I just found a discrepancy between UTM and UTMIP. I tried the following pair.

Lat: 56d 16' 35.46" N
Lon: 3d 23' 46.82" E

UTM Zone: 31
UTM coord: 6237064.70 N, 524543.14 E

It looks like the UTM seems working correctly, but UTMIP produced opposite sign for longitute coordinate. For this test, I used "International 1909" datum. Please let me know if I am missing something here. Thank you!
