Some months ago I needed to produce a geographic plot with two locations highlighted. geoaxes with the satellite basemap and geoscatter did the job perfectly:
p = geoaxes('Basemap','satellite'); hold on
geoscatter(39.08,17.13,'filled','g');
geoscatter(41.12,16.87,'filled','g');
geolimits([32 43],[12 27]);
I got back to this code these days, and re-run it to export the figure again, but now the satellite basemap is unavailable and the following error message appears:
Warning: Unable to access the Internet, showing "missing" tile where 'satellite' is unavailable. See Access Basemaps in MATLAB.
I tried to export the figure anyway; it seems that some parts of the map can be viewed, but this depends on the zoom level. Maybe there are some parts of the basemap saved in the cache from when the code worked?
The Internet connection in my office computer is on, but access is provided through a proxy, so I tested the same code on another computer with a direct connection and the problem re-occurred. The same occurs when I change to other basemaps hosted by Esri, such as streets or topographic.
Reading the documentation at this link I understood that I can download some basemaps via add-ons to use them without a connection, but unfortunately satellite is not available among the add-ons since it is provided by Esri. I can use another basemap, but nonetheless I am wondering if I am doing something wrong or something has changed in the exchange between Matlab and Esri sometime in the past.
