Re: [Talk-GB] OpenHants - doing something with the Hants CC data in the meantime
Hello Rob, Sorry for the late reply on this. Basically how it works is: - the shapefile was converted to Postgres SQL using shp2pgsql; - the data was imported into a PostGIS database; - some custom code (actually same underlying code as Freemap) was written to fetch data as GeoJSON from the database by bounding box; - Leaflet was used to produce the overlay; this is quite easy as Leaflet automatically handles GeoJSON. I'll try and write it up as a blog post. Some (old) code for doing this is on the Freemap github site; I'll try and update it in the next few days.

Is there any guides for how to do something similar? I was trying to visualise the Natural England data using Leaflet but failed miserably as the shapefile is too big. Your website appears to load just the bit needed. Would I be able to use some of your code? Cheers, RobJN p.s I'm not hugely tech savy, but with a simple set of steps (e.g. Load data in x, tweak code where there are references to yz, etc) should be enough to get me started as I can research the details on google. ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] Wychavon Way Revised Route
On 13 June 2012 22:29, Steve Brook srbr...@tiscali.co.uk wrote: Worcestershire County and Wychavon District Council have revised the route of the Wychavon Way long distance footpath so it now resides entirely within the Wychavon District. [snip] To update the relation to reflect the new route; I have moved sections of the original route that were demoted into child relations contained within the original relation. I think this is a better solution for retaining the old route information I'm not sure I agree here. Surely any bits of route contained in sub-relations of a main relation will be seen as part of the route defined by the main relation. So if you ask an OSM-based tool for the route of the Wychavon Way as defined by the OSM relation, you'll end up with the old and new routes together. If you want to continue to record the original Wychavon Way and at the same time avoid duplication of the parts that are common to the old and new routes, I think you'd want to do the following: Relation #1 for the original Wychavon Way -- contains relation #3 as a child-relation, together with the ways that are in the old route but not in the new route. Relation #2 for the new/current Wychavon Way -- contains relation #3 as a child-relation, together with the ways that are in the new route but not the old route. Relation #3 for any ways that are common to both the new and old routes. You could even go a stage further and define two other child-relations for the sets of ways that are in the old route but not in the new route, and the ways that are in the new route but not the old route. Then each of the two main relations #1 and #2 would just contain two child-relations. Personally though, I think I'd just keep things simple and have one standard relation (directly containing all the ways) for the new/current route -- this is surely the most important thing. Then, if you want to keep the data, another relation (directly containing all the ways) for the old/original route.

Re: [Talk-GB] OT: Is Bristol the UK's only cross-border city?

The pitch being in Wales and some of the car park and offices in England. I think this is a little curious, but it doesn't seem to imply any administrative ambiguity as there is in the Severn Estuary. May be a bit hard to swallow for Chester FC that their home ground is in Wales though. There are probably loads of buildings in the UK which straddle a border. I wonder how that is handled for council tax, planning etc. In Baarle-Hertog (BE)/Baarle-Nassau (NL) (see [1]) this happens a lot; for administrative expedience the nationality of a house is determined in practice by the country in which the front door is located. But there are also cases where the border goes through the front door. When the borders were re-surveyed a few years ago one house had suddenly switched countries. The problem was resolved by moving the front door by a couple of metres. I heard of someone who lived on the boundary between Bromley and Southwark, a third of the council tax went to one council and 2 thirds to the other one. Eventually they moved the boundary such that they were completely in one council area. Shaun ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
