This relates to some work I did on the Cornish county boundary a while back, the same also has happened at Newton Ferrers, just south of Plymouth. Whilst remapping the boundary, I also pushed the coastline further up the channel.The new boundary has rendered, and the removal of the

Hi Kevin, Agreed, it looks wrong... The data came from the OS Boundary Line data, which I took from the gpx trace from Colin's site, http://csmale.dev.openstreetmap.org/os_boundaryline/ I wish I knew the reasoning behind it... I can understand the boundary being at the low water mark,

[Talk-GB] Using UK postcode data to generate a heat map

2013-01-30 Thread David Fisher
Hi all, A friend has come to me with an interesting-sounding request, and I just wondered how feasible it might be. He has a database of UK postcodes and some measurement or other (not sure what yet) and would like to create a heat map. Neither of us are techies, but I've been contributing to OSM

Do you know about openheatmap (http://www.openheatmap.com )? Basically you can supply spreadsheets of locations vs data and it will do the graphics for you. It doesn't know about postcodes, but if you have the means to get locations for postcodes you don't have to do any of the rest. David

Hello everyone, Related to another thread: has anyone got a (can be old) version of processed_p.shp which is known to be more or less free of bugs/defects for the whole of the England/Wales coastline? Reason being I have some odd flooding artefacts on Freemap (mostly in N Wales) which were

So it seems, although the OS at least manages to limit the ugliness factor. I wonder if there is some historical reason for it? Next time I use the ferry I'll ask the guy to make sure he stays in Devon :] Kevin On 30 January 2013 11:37, Steve Doerr doerr.step...@gmail.com wrote: That's how it

I found this report from 2000 which addresses exactly this point. http://jncc.defra.gov.uk/pdf/tyldesley_reportall.pdf It still doesn't answer the question why Dittisham though. According to one algorithm it should cross the river at the tidal limit, which is in Totnes, far above Dittisham.

Thanks Colin, Thought there may be an official answer out there somewhere. I’ve been working around the coasts of Somerset Devon, and splitting the boundaries, coastline going to the High Water Mark, and the Admin Boundaries going to the extract, (LWM in most cases) Jason From: Colin
