Nice. Glad to know that there are some people who think that going onto private land is a bigger wrong than wantonly destroying native wildlife!

The one which comes to mind is the national database of native Black Poplars (Populus nigra betulifolia) maintained by the BSBI recorder for the taxon, Fiona Cooper. In her book on the tree (available at remaindered book specialist Postscript Books at the moment) she kept many the details of many records secret. Apparently Black Poplar enthusiasts were a bit casual about walking on private land in their quest with the result that landowners were destroying the trees.

Here's one bit of work I did mapping trees: http://tom.acrewoods.net/2011/04/19/maps-open-data-and-activism-on-the-heygate-estate/ It's also worth reading this report, particularly the section from paragraph 4.11, which gives some idea of the context of street tree data collection and availability by councils: http://www.london.gov.uk/sites/default/files/FINAL%20street%20trees%20report%20010611.pdf Since then a few councils have released some more semi-open data (encumbered by the usual uncertainties around OS licensing), but they aren't doing so in a way that makes it easy to track whether threes have been planted or felled, and few councils give useful open data on attributes like height, circumference and canopy size that would enable someone to estimate the spread of roots.

At this stage I think it's best to confirm on Andy Mabbett. If that's OK can Andy pick up on the use cases that have been mentioned here to get more info from the contributors mentioned? We have a 30 min presentation slot and 30 min Q&A at 1700 on March 31 at IBM SouthBank Regards Brian On 4 March 2014 13:37, Tom Chance <t...@acrewoods.net> wrote: I could possibly do this, I've done various projects to do with mapping trees and know a fair amount about tree and climate change policy. But I'm not an expert on the underlying OSM data model and API. If anyone wanted to chip in thoughts on stable URIs I'm all ears.

Anyone up for this - either with the topic suggested or with a suitable alternative? Regards Brian A few weeks ago, we had a use case webinar with the CIO of the City of Palo Alto who told us about an local initiative to tag trees with lat/long, genus, size, etc. During the call, we asked him if he also considered tagging the trees with URI's and of course he hadn't. Following the call a colleague sent me an article about how tree roots often damage natural gas lines and lead to widespread gas leaks. Methane is 20x more dangerous as a greenhouse gas than CO2, so gas leaks are a leading cause of global warming. We would like to find an openstreetmaps speaker who can talk about the value of mapping trees and gas lines, and many other things, with URI's. Would you be able to discuss this? We will be meeting on March 31 and April 1 at IBM Southbank, and would love a presentation/discussion the morning or late afternoon of the 31st. Would this topic and date fit? _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb -- http://tom.acrewoods.net http://twitter.com/tom_chance -- http://tom.acrewoods.net http://twitter.com/tom_chance _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
