Quick update here... I think I've finally put together some shapes that are appropriate for Maine's history and given them some minor tagging.
ohm:2660783 <http://www.openhistoricalmap.org/relation/2660783> : Maine District of Massachusetts (US Claim, 1783 (Treaty of Paris) - 1842 (Webster-Ashburton Treaty)) ohm:2668784 <http://www.openhistoricalmap.org/relation/2660784> : Disputed Territory in Maine District of Massachusetts (UK Claim, 1783 (Treaty of Paris) - 1842 (Webster-Ashburton Treaty)) ohm:2660785 <http://www.openhistoricalmap.org/relation/2660785> : State of Maine (as of 1842 (Webster-Ashburton Treaty)) Of note, the Maine District of Massachusetts became the State of Maine in 1820 - the only thing that changed in 1842 was the Northern border. Not sure yet of how to manage these types of changes to geo-object attributes without time-based tags. I've also tried to put some links to other data sources, such as Harvard maps as a source, Mapwarper references for warped versions of the Harvard maps, and wikipedia, where appropriate. So... in theory... a filter that selects for 1800 should see the two claims in Maine - UK and US, but not the current Northern border of Maine. Likewise, a filter that selects for 1850 should just see the current outline of Maine. - Jeff On Wed, Apr 29, 2015 at 3:17 AM, Albin Larsson <[email protected]> wrote: > Hi, > > Great Jeff, I lately started mapping Regent´s Park in London for the use > as a starting point in iD, for London we got multiply historical aerial > imagery, I thought that it would be a good first user experience...
