initial page state shows data through 2005 #2

The default, initial view of the page on load should show forest (green) and deforestation through 2005 (red). These correspond to image values 0 and 1, respectively.

It might be sufficient just to start the slider at December 1, 2005 and increment by month after that.

Which is the best set of tiles to use? "ecohack" or "newecohack" ?

robinkraft commented 13 years ago

newecohack has a newer creation date. I'd stick with that for now, but I'm about to upload the tiles to s3. I'll send along a path in a few.

Ok, I'll work with 'newecohack'.

As a heads up, I'm pretty sure in order for Javascript to manipulate/inspect the image data, the JS and the HTML page need to be loaded from the same domain as the tiles. So S3 is fine for pushing everything, but I don't think you'll be able to use it locally unless you use the proxy technique through Node (or similar) that is outlined in the original Visual-Raster Readme file.

Ah good point. So that could be annoying for testing. If you want the full tile set locally, I've uploaded it here:

http://forma.s3.amazonaws.com/ecohacknyc/ecohacknyc.tar.gz

And the public tiles are here:

http://s3.amazonaws.com/forma/ecohacknyc/

I initially set the permissions incorrectly though so it'll take a minute or two for the correct permissions to propagate.

Fix posted to: http://elementstream.com/forma-vis/test_pixel/maps_threshold_NEW.html

... facing issues w/ pushing changes up to github (see note on #4 regarding permissions... may just fork the project)

robinkraft commented 12 years ago

Brian, I took your changes from elementstream.com and commited them to the master branch - which I then pared down just to the project files we're actually using. There's also an updated readme.

The tiles and HTML/JS files are now on S3:

http://forma-vis.s3-website-us-east-1.amazonaws.com

The cross-domain security policy is really annoying, but this is fine.
