[Talk-GB] School mapping - Who's involved

[Gregory]

Cheers Dave, the "sets" feature of Overpass is good to know about.

However the set logic isn't what I'm after as such.
I want to all schools that have an isced:level tag to be blue dots, all the
schools without an isced:level tag to be red dots. You could display other
comparisons, such as schools with a name tag as blue dots and schools
without name tags as red dots.

Overpass is primarily an fancy export tool, so this feature isn't probably
beyond it's scope/objective. If I really wanted I could use Overpass to
export all schools and then use QGIS to colour them depending on what tags
are present or not.
