Having taken a few week’s break from administering the SMP, I just noticed that the weather, clouds and panoramio layers no longer appeared to work in the SMP mapping pages. A quick search online shows that Google have removed all of these worldwide, for all users, without providing alternatives.
A most disappointing move: so that’s Google Earth, weather, clouds and panoramio removed, or no longer available from within Google Maps. One wonders where it will end - quite probably every one of these formerly free services/layers will have to be paid for in the future.
What can I say? I personally found these layers very useful, and I’m now sadly forced to remove, or at least disable, the relevant controls in the mapping pages.
