Hi Andrew,
The Before OSM layer comes from FOSM, a fork of OSM in end of 2012. See
http://www.fosm.org/
I only need to provde a Client HTTP page that access external FOSM and OSM/HOT
layers. With this light solution, I have no database to maintain. This is also
a practical way to compare rapidly any area in the world. This Compare map is
used in general for communications about mapping progress. The results are in
general satisfactory enough to illustrate the mapping progress. We can provide
a more precise measure of progress with statistics of contribution.
The comparizon is in general ok since the FOSM map did not evolve rapidly since
the end of 2012, in particular in development countries where HOT and partners
have mapping projects. This way we dont need to develop scripts to extract
history data end produce map tiles each time we want to make a comparizon for
an area.

These tools are really cool! What is the date for the before tiles, and is
there a way to specify them?

Hi Pete,
The Before tile is back in the OSMCompare page. See compare for Gueckedou
http://pierzen.dev.openstreetmap.org/hot/leaflet/OSM-Compare-before-after.html#14/8.5637/-10.1331
I just corrected the tile link with the new tile url specified in map.fosm.org,
the OSM fork project that let us compare when we add new infos to OSM.
We might have to consider eventually to host a copy of these Before tiles
somewhere else. If the same Humanitarian style was used for the Before and
after tiles, it would also make a better map compararizon.

Hi all, happy new year!
I have used Pierre's website for showing impact of Missing Maps activities
extensively in the past:
http://pierzen.dev.openstreetmap.org/hot/leaflet/OSM-Compare-before-after.html#10/27.9083/85.5286
But, for a while now, it has not been working. Does anyone know of an
alternative that shows a before and after map?
Cheers,
Pete
