It is a murky situation and you’re right Martin, we all click licences without reading to get to the interesting stuff.
You could argue that my clip shows my route and significant details of the map are obscured by the route markers such that it’s indicative and you couldn’t use without caveats. Or you could say it’s more than detailed enough.
The media licence from the OS is free and doesn’t expire and allows 1000cm^2 per issue and a single extract of 625cm^2. The licence applies to online and print use. And SOTA now has one for the reflector! The moderators will keep an eye on OS data pasted in and for the sake of argument as defining what “an issue” is for a continuously updated weblog/forum, we’ll make those limits the daily limits and assume we run like a print newspaper with one issue per day.
In the map clip placed in my report, that comes from the 1:50k map where grid squares are 1cm x 1cm. The data shows about 4.5cm x 3.5cm of raw data before de-resolving and magnifying. Or 14.875 cm^2 (if I have done the maths right) of the 625cm^2 allowed per clipping.
I can understand the idea of worrying about only what matters. However, the people saying that wouldn’t be the people chased for non-compliance. In that case it’s easy to say
