Hi, I've made something I think a few of you will find interesting. After seeing a couple of posts on the OSM subreddit about historical data, I figured it would be nice to be able to what changes have been recently (-ish) made in my area.
I followed a method fairly similar to the one in this post (https://hackmd.io/XfrY334rS7CV0tnPzx8Wvw), however after filtering the history file to the time I wanted I imported it into Postgres instead (using osm2psgl). Once I everything in Postgres I first tried to use Mapnik and the nik4 tool, which worked well enough but it was difficult to see the changes on a larger scale, as I had to manually create each image. It also wasn't great for comparing it to the current map, as I had to switch between images awkwardly. Therefore I decided that it'd be best to just create a full on slippy map, using the normal stack, a-la switch2osm. I took some inspiration from OSM Then and Now as to the adjustable overlay, and followed an example on the Mapbox website. You can see the result at https://maps.honeyfox.uk/. Bear in mind it is hosted on my home PC so don't expect it to be particularly performant or reliable, and it is limited to the UK. Ideally you be able to adjust the time period the map shows, but I cannot see a way of achieving that without dropping the database and importing everything again, which is too demanding to be done on the fly. Let me know if you have any thoughts or ideas :) Cheers George _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
