deg2utm

Function to convert lat/lon vectors into UTM coordinates (WGS84)

Description

This function is based on UTM.m function by Gabriel Ruiz Martinez, but instead of providing a GUI it works with vectors of coordinates.
[x,y,utmzone] = deg2utm(Lat,Lon)
% Example 1:
% Lat=[40.3154333; 46.283900; 37.577833; 28.645650; 38.855550; 25.061783];
% Lon=[-3.4857166; 7.8012333; -119.95525; -17.759533; -94.7990166; 121.640266];
% [x,y,utmzone] = deg2utm(Lat,Lon);
% fprintf('%7.0f ',x)
% 458731 407653 239027 230253 343898 362850
% fprintf('%7.0f ',y)
% 4462881 5126290 4163083 3171843 4302285 2772478
% utmzone =
% 30 T
% 32 T
% 11 S
% 28 R
% 15 S
% 51 R
%
% Example 2: If you have Lat/Lon coordinates in Degrees, Minutes and Seconds
% LatDMS=[40 18 55.56; 46 17 2.04];
% LonDMS=[-3 29 8.58; 7 48 4.44];
% Lat=dms2deg(mat2dms(LatDMS)); %convert into degrees
% Lon=dms2deg(mat2dms(LonDMS)); %convert into degrees
% [x,y,utmzone] = deg2utm(Lat,Lon)

Excellent!! And Thank you. This is applied for Korea.

Excellent Script! I wonder if you would provide some comments for the calculation section. I've compared some lat/lon data to actual x,y profiles; however, I've found that I must multiply the x and y valuse derived from deg2utm by approximately 3.2 to match the actual values?! Thanks! Again, great script!!!

I have my Lat/Lon coordinates in Degrees, Minutes and Seconds (as in your Example 2). However I am missing the 'dms2deg' and 'mat2dms' functions. Are these in some toolbox or part of this submission.

Hello!
I have a question about this script:
I want to convert lat lon points in the Northern Shelf Sea (Europe) to coordinates which have the unit meters. So I thought using UTM coordinates was the best solution.
However, the area is quite big (1000km x 1000km) and contains different zones. So after converting, my points are not in the right order any more. So either it is simply not possible to have points of different zones in one data base or the script makes some mistake.
Can somebody help me with this issue?
Thank you. Anna
