Hi!
I'm currently trying to project a structure array containing 3 Fields: latitude, longitude, and altitude (bathymetry), which are 1801 x 1 double, 21601×1 double, and 1801 x 21601 int16 respectively.
The data covers latitude from -30 to 0 and longitude from 0 to 360 in 1-minute measurements (though I have a separate copy of the data with longitude measuring -180 to 180). I chose the 0-360 format because the area I need to map straddles the longitude line opposite the Prime Meridian (off the eastern coast of Australia).
I can currently plot the data in a nice-looking pcolor plot, however the map is not useful unless I can display it as a map projection (because the spacing of latitude is not uniform as the pcolor depicts but decreases as distance to the equator decreases). Ideally, I'd like to use a cylindrical mercator projection since my area of interest is near the equator.
So…after that lengthy description, how can I get my structure array containing bathymetric measurements and lat/long fields into a mercator projection? I assume the mapping tool could have some function that could help, but I'm at a loss as to how to do it. If there's a formula I could apply to the data I could do that too.
Thanks for your help, it is much appreciated!
