animated map of day one
Posted on: 2/6/2016 6:26:11 PM
Gettysburg has always been a mystery and a source of fascination to me because it is so COMPLICATED. Three days...and at some times there's multiple battles going on at the same time. Also all the puzzles about the motivations of the various commanders. It's a very complicated battle, right? Then I retired from Microsoft and was looking for a coding project. It occurred to me I should ANIMATE the movement of all the brigades across the battlefield. That would make it so much more clear! Just pin down what I could about where each brigade was at specific times, then just interpolate across the gaps.

I mostly used 3 sources for information:
the Smithsonian maps, here: http://www.smithsonianmag.com/history/A-Cutting-Edge-Second-Look-at-the-Battle-of-Gettysburg-1-180947921/?no-ist
Gottfried's 'The Maps of Gettysburg'
Pfanz's 'Gettysburg: The First Day'

...and found a wonderful Corps Of Engineers' topo map to use as a background to draw on top of, digitized and available from the Library of Congress. I figure because it's a hobby project it counts as 'fair use'.

I used HTML5, JavaScript, and the EaselJS animation library. Started with an 'alpha' version as a proof of concept. The latest is a beta version of the day one map. It runs from 8am to 630pm. Links to the map and a YouTube video demo are here:

demo video (3 minutes, 15 seconds): https://www.youtube.com/watch?v=1oEM3WTUGlI
the map itself: http://www.clarksoncs.com/Gettysburg/dayOneBeta.html

One of the dilemmas I have is how to handle artillery batteries. (So far I'm ignoring them, only tracking cavalry and infantry brigades.) I've already started on day two.
Let me know if you have suggestions or comments!

Very nice. Something like this for Waterloo would be very interesting as well.

Cheers

Very cool!! You might want to mention that it's not supported in Firefox. I found that out the hard way..

(but works great in IE and Chrome)

Is it possible for someone to put this site, on a click & go there?, like a "read more" click & your there?

Thanks,

Very cool...have you figured out how to add the artillery?

Suggestion/Comment - I like the function to be able to look up specific units, but it would be much more intuitive if the units already had labels over them. Either that or if you mouse over them, they show their units name, or something along those lines.

I'm thinking about it, as in "how do I do that?"
It's simple enough to add the unit icons to show artillery batteries.
What would be really interesting is to show, somehow, when they were firing and what the targets were; rather than just a static icon...
It's definitely something that's missing right now.

Yes, I agree.
Mouse over would be better.
Right now I'm working on a 'day two' map. My plan is to release an updated 'day one' map at the same time as I release the alpha version of the 'day two' map.
Mouseover might show up in the 'day two' map. I have to figure out how to make it work.

Here's the demo link [Read More]

And here's the map link [Read More]

The base map, of course, is the Warren Map (excellent choice)

I am loving this map and animation. Excellent base map. I especially enjoy the pause & highlighting options. It still moves painfully slow with Firefox, even at max speed, but switching to a different browser is not a big problem. Thank you for this wonderful tool.
