geoglobe in Mapping Toolbox

I'm getting started with the Mapping Toolbox and found sample code to try but get an error:

uif = uifigure;

geoglobe(uif)

g = findall(groot,'Type','globe');

Undefined function or variable 'geoglobe'.

The system does not find the function 'geoglobe' (yes, I do have the Mapping toolbox installed). One tip suggested running this code to see if my system has hardware graphics support:

fig = uifigure;

ax = axes(fig);

info = rendererinfo(ax);

info.GraphicsRenderer

ans =

'WebGL'

The result seems to indicate that I do have the hardware required. Suggestions?

geoglobe was introduced in R2020a. Could you check your MATLAB version?

[Robert Mueller]

Thank you - that explains it! I am running version 2019a.

Follow-up question - I generate geo plots of aircraft surveillance data with lat/lon coordinates over various regions of the US. Is there a way to lay down terrain features similar to Google Earth satellite imagery to the background of my data plots in MATLAB 2019a?

[Kojiro Saito]

geoplot is available from R2018b.

For example, you can change the basemap of geoplot to satellite which is higher resolution.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;
gp = geoplot( [latSeattle latAnchorage],[lonSeattle lonAnchorage],'g-*');
gx = gca;
gx.Basemap = 'satellite'; % Available from R2019b
geolimits([45 62],[-149 -123])

You have Mapping Toolbox, you can add your custom using addCustomBasemap function. The help page contains how to change the basemap to OpenStreetMap and USGS National maps.

[Kojiro Saito]

My apologies. "satellite" option of geoplot is available from R2019b.

Another way is using webmap and wmline.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;
webmap('World Imagery')
wmline( [latSeattle latAnchorage],[lonSeattle lonAnchorage]);

This works well in R2019a, too.

Answer 2

[Robert Mueller]

Thanks, Kojiro... I was able to get the terrain background - excellent feature. However, the 'satellite' Basemap option that you suggest is not available with my MATLAB version. Here's what I get when I run your suggested script verbatim:

Error using matlab.graphics.axis.GeographicAxes/set.Basemap

Expected Basemap to match one of these values:

'darkwater', 'grayland', 'bluegreen', 'grayterrain', 'colorterrain', 'landcover', 'none'

The input, 'satellite', did not match any of the valid values.

Again, I have MATLAB version 2019a Update 8.

All of the Basemap options listed in the error message above worked fine. Thanks again for your help. - Rob
