OSM historical data

General talk
1

Hi there,
I tried to download OSM data from different years in an area of Kenya but downloading the whole planet-osm is not feasible, as it takes too long and it’s certainly far more data than what I need.
is there a way to, at least visualize data from different years? I think that would be enough for me.
Thank you very much

maybe some hints are at https://help.openstreetmap.org/questions/13277/historical-osm-data

Martijn van Exel wrote this code:

to visualise how OSM has changed since 2007. The demo’s no longer online, though.

Geofabrik has some Kenya extracts here:

so if you’re looking for changes since October that might work.

If you’re happy to compare “now” with 12 September 2012, then FOSM’s map http://map.fosm.org/ may be useful. That will have been updated by FOSM contributors since 2012, but I suspect that there won’t have been many in Kenya.

Or have a closer look at the famous overpassAPI that can deliver raw OSM data by own created queries … see http://wiki.openstreetmap.org/wiki/Overpass_API in general

See http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Attic_data_.28.22date.22.29 in detail how to define there a date that you can use when saying: I want raw OSM data drom that area XY with date from TTMMYYYY
