GEplot

GEplot uses the same syntax as the Matlab plot function, but draws over Google Earth graphs

Description

Creates a file in kmz format that can be opened into Google Earth.
GEplot uses the same syntax as the traditional plot function but requires Latitude and Longitude (WGS84) instead of x and y.
Examples:
GEplot('my_track',Lat,Lon);
GEplot('my_track',Lat,Lon,'o-r','MarkerSize',10,'LineWidth',3)

Colors supported: blue, green, red, cyan, magenta, yellow, black, white.
Symbols supported: point, circle, x-mark, plus, star, square, diamond, filled square, filled diamond,filled circle.

Each plot appears as a separate folder within GE; within the folder line and marks are separated in two layer. Hence it is very easy to show/hide different plots.

If you need to convert from UTM to Lat/Lon you may use utm2deg.m, also available at Matlab Central.

• MATLAB release: MATLAB 7.1.0 (R14SP3)

Idea is great! Google Earth in Matlab! But it took me 10 min of my time to fail to overcome the elementary error (after I installed software and set the path).

>> GEplot('my_track',Lat,Lon);
??? Error using ==> iofun\private\getArchiveEntries
File "GEimages/none_b.png" does not exist.

Error in ==> GEplot at 217
zip(filename,{strcat(filename,'.kml'), iconfilename});

Note: I set Lat and Lon to actual vectors.

Maybe it make sence to check first if what you submit actually works.

But, again, the idea is great!

[Rafael Palacios]

The problem found by Tomas Frank has been corrected in the currently available version.
GEplot is easy to learn because it uses the same syntax as plot. If you need to draw other kind of objects, you may consider using Matlab2GoogleEarth toolbox, also available at Matlab Central.

Great job! it works very nicely. I recommend adding the capability of plotting multiple trajectories at once. So the 'Lat' and 'Lon' would be matrices rather than vectors. (similar to the Matlab's plot() function) I did it myself and it worked perfectly.

[Andrew Robertson]

This is the simplest way to draw my vectors of coordinates in Google Earth.
Thanks!

[Eric Gayer]

Thanks for this simple and so usefull code. Thanks also for adding Labels. Now I can plot my sample site, with their name on GE... Thanks again ! This is gonna be really usefull for the geosciences community.

i am trying to run this tool but it gives me this errorfp=fopen(strcat(filename,'.kml'),'w');
if (fp==-1)
    message=sprint('Unable to open file %s.kml',filename);
    error(message);
end

can you tell me whats wrong with i have got my lat and lon in decimal format is that good enough it doesnt create the .kml file and if it does where is it gonna store it

[R. LeFande]

GEplot('my_track',xx,yy)
??? Undefined function or method 'GEplot' for input arguments of type 'char'.

What am I missing? Thanx.
