plot depth values for each location (latitude, longitude)

hello everyone!

I have three vectors ( 14084 x 1 double format) that contain respectively latitude, longitude and depth values. I would like to plot the depth values for each pair of lat and long values.

Can anybody help me?

Thank you a lot in advance

Hi @Tiziano Bagnasco,

I assume you want to get a spherical plot with elevations from your data. To do so, the 'surf' function can be used once the data has been properly formatted in the form of a grid rather than 1-D vectors. The 'sphere' functio can be used to understand how the data needs to be formatted. Here's some sample code to help you out along with some relevant documentation:

lats = -90:1:90;
lons = 0:4:360;

[lats, lons] = meshgrid(lats,lons);

elevation = rand(size(lats))/5;

R = 15; %Radius of sphere.

X = (R+elevation).*cosd(lats).*sind(lons);
Y = (R+elevation).*cosd(lats).*cosd(lons);
Z = (R+elevation).*sind(lats);

surf(X,Y,Z);
axis equal;
