Hello, I want to plot a globe mesh like this image:
with data points distributed over the longitudes and latitudes (I have the locations). How I do I do that please? Thank you

Hey Collin,
First of all, really neat looking map when you just plot the points at which the data was taken:
Using griddata, you can mesh out your current dataset into a grid:
latmin = min(lat_piomas);latmax = max(lat_piomas);lonmin = min(lon_piomas);lonmax = max(lon_piomas);gridSize = [100 200];latvec = linspace(latmin, latmax, gridSize(1));lonvec = linspace(lonmin, lonmax, gridSize(2));[LatQ LonQ] = ndgrid(latvec, lonvec);ThickQ = griddata(lon_piomas, lat_piomas, thickness, LonQ, LatQ);From there, it's a simple matter to show the data in whichever format you like:
figureaxesm('mercator', 'MapLonLimit', [0 360])geoshow(LatQ, LonQ, ThickQ, 'DisplayType', 'surface')
And if you want to get real fancy, you can use topological data to show the elevation of the surface, while using the color to show the "thickness" data. Here's an example using built-in example topography data:
% Get example topography data
load topo topo topolatlim topolonlimRtopo = georefcells(topolatlim, topolonlim, size(topo));ElevQ = geointerp(topo, Rtopo, LatQ, LonQ, 'cubic');% Display the surface
figureaxesm('mercator', 'MapLonLimit', [0 360])geoshow(LatQ, LonQ, ElevQ, 'DisplayType', 'surface', 'CData', ThickQ)daspectm('m', 1000) % To exaggerate the height of the topography
Hope this is helpful and interesting.
