Awesome, well I forgot to update my tags here for my opening slide to show what came before my current presentation but the key point on this slide talking about history is that I've added a start date tag and that's where all of

our mapping in open history open historical map begins and let me get this in here so for those of you who aren't familiar and I have a lot of gratitude to those of you followed and cheered us on along the way OSM is essentially a or OHM is essentially OSM with a slider time slider and an empty

database waiting for people to fill it in we have stacked the fork or we have a fork the stack including a big push this morning which might explain my slippy tongue but that was a very exciting maneuver for those of you who have deployed software to do it before a big talk was usually ill-advised but

you know this is a grassroots team of people building it from within the grassroots movement that is OSM and any work that we do is made possible because OHM uses the same tools as OSM, ID, JAWS, you name it so all the same

tools and very frequently will come people will come to us and say hey what about tool X and with an easy change of an endpoint they're off and running now since this is mapping USA the question is what's the OHM doing about this I thought I'd do a quick review of what most people might imagine in their mental models of history of the United States so there were the indigenous

people were here the Mayflower landed Plymouth Rock landed on some people Jamestown developed and you have 13 colonies blah blah blah each of these stories each of these segments in the u.s. has its own map that if you go looking online to find and you have to go from one thing to another and try

and superimpose them mentally but kind of like the old how many licks does it take to get to the center of a tootsie pop the question is how many maps does it take to tell USA's history and what I'd like to propose is you could do a lot of it with just one and something like OHM so let's do a quick demo and hope I don't break everything this is by the way that blank

screen you saw just to see that's what it would look like if our deployment didn't work this morning so the here's United States in about 1820 I like to zoom in here because it shows a little bit of westward expansion but as you can see with boundary data that we've used from the Newberry

library we've been able to populate you can go back to about 1783 right now and then you can go forward in time to check out what's going on with westward expansion and states getting adopted so kind of cool I'm catching my breath every time I slide the slider here and that is you know in a nutshell the

beginning of a framework for talking about American history and so now one of the things that's interesting is that original map I showed you has a lot of

conflicts a lot of little things that you might not have noticed in at first disputed territory in the northeast corner of Texas you've got border disputes with Canada a couple places you even have some interstate boundaries so let's go here there's a you know a little a little corner of Massachusetts it's gone from Massachusetts to New York and there's a

very colorful story behind Boston's Corner Boston corners but the point here is that you can use OHM to start telling stories and you can see that we have it set up so you can add some data rich data like pictures to the inspector here is a case this one is for Jess it's the Toledo strip

which is a war or also known as the Michigan Ohio war the Toledo war a little strip of land that as usual in an interstate concern was due to a surveying error but again small things small stories that can be told and

but there are other things that we're working on in this project and one you might have seen there is Comancheria and it's an interesting area of land in that the questions that the tools we currently have for mapping don't really apply to non what I would call non-European cultures I mean what's a

boundary you know and the very basis the very act of trying to map this area immediately invokes a lot of very challenging questions and I just put this up there's a placeholder I highly recommend that book and that's a

cool thing about OHM a little bit is that you can take concepts from books or ideas and start to build out resources that other people can use and compare to the resources other people created for other books for example this just highlights the difficulty of finding original sources and the importance of finding original sources here you have Comancheria in the middle you

have the source that I used in the University of North Texas a lot of a lot of panhandle action action here today on OSM and then you have this resource on the right it's from Wikipedia and the question is where did that come from I can't tell you and it is all over the web but who knows someone just drew a red line on an old map to make it look real so

those are the things you kind of explore so what's it gonna take you know to do a good job or you know why am I talking to you guys well I need your imagination your creativity in your data and I need you you know to tell your own stories it doesn't matter how large how small but we're

building something from the ground up that we think is pretty cool and we're gonna have a workshop tomorrow on birds of a feather it's kind of gonna be a work Birds of a feather workshop and we invite anyone to meet me you know at the table and there's Stephen Johnson once again I don't know what he's doing in all these slides Maggie love the beach theme and I'm out
