(Late to the party... I apparently didn't check the map to find out how long it wold take ;) ) On Wed, 29 Nov 2017 10:27:10 +0100, Michiel Bijl <michiel.list@moiety.me> wrote: > On 29 Nov 2017, at 09:04, Matt King <a11ythinker@gmail.com> wrote: >>> The polygon is drawn around a point on the map … does that point have >>> a name, address, or something to identify it? > > ... an actual list of all the point within that area would be pointless > (ha) because there would be too much data.

Filtered matters. Most people have a sense of whether something in a given direction is closer than some other thing in that direction, or further away. My initial suggestion would be to look at the polygon, and then go around it (e.g. clockwise from north) finding the points of Interest closest to the edge. Unless this is high-precision - and since you are not doing rocket science for travel of actual rockets, it probably cannot be - something near the boundary is a useful guide. If you don't find anything vaguely close, you might consider "the pub is well inside, the train station is far outside" or something similar. Allowing people to trace points of interest along a very broad ray, like "2 minutes, the top pub, 9 minutes the dodgy pub, 14 minutes the bottom pub, 15 minutes the train station, 27 minutes turnoff to woopwoopwest" might also be useful. Remember how people *use* maps and directions. They don't want every last detail, excpet very close to what they are looking for, but they look for landmarks or identifiable shapes of things - e.g. the dog-leg road, the big roundabout, the shoe shop, the train station, the terrible busker... I'd be interested to hear what you actually *did*, and why. cheers cheers -- Chaals is Charles McCathie Nevile find more at http://yandex.com
