Hi Bradley,
To visualize the bathymetry in 3D space, you can use the surf function in MATLAB.
The code below reads the bathymetry data from the TIF file using readgeoraster, creates a grid of latitude and longitude values using meshgrid, and then uses surf to plot the bathymetry as a surface. The daspect function is used to set the correct aspect ratio for latitude and longitude data. Finally, the plot is rotated using view for better visualization. Here's an example of how you can achieve this:
[A, R] = readgeoraster('BathyRaster.tif');
latlim = R.LatitudeLimits;
lonlim = R.LongitudeLimits;
% Create a grid of latitude and longitude values
[lon, lat] = meshgrid(lonlim(1):R.CellExtentInLongitude:lonlim(2), latlim(1):R.CellExtentInLatitude:latlim(2));
% Create a surface plot of the bathymetry
figure
surf(lon, lat, A, 'EdgeColor', 'none')
demcmap(A)
% Set the correct aspect ratio for lat-lon data
daspect([1/cosd(mean(lat(:))), 1, 1])
% Add labels and title
xlabel('Longitude')
ylabel('Latitude')
zlabel('Depth')
title('Bathymetry')
% Rotate the plot for better visualization
view(35, 60)
Please note that the code assumes that the bathymetry data is in meters. If the data is in a different unit, you may need to adjust the plot accordingly.
