Hi Johannes:
indeed this functionality did not exist. However, I uploaded 2 new files (ge_point_new.m and demo_ge_point_new.m) to the Google Code repository (revision 28), which may solve your problem. Let me warn you though that 500.000 points with popup menu will generate huge KML files. Having said that, good luck on your work and thanks for the rating.

Some of the issues raised in previous posts have been resolved in revision 27 of the googleearth toolbox --check the Google Code link above or "http://code.google.com/p/googleearthtoolbox/"

Would prefer if a warning is issued when no action is being taken. Also with the default action being 'save all variables by default', I expected that
savex(filename);
would automatically save the workspace to filename but this is not the case. Could you get this simply to redirect to
save filename;
when no variables are specified?
