Hi, I have a local tile server. I use osm2pgsql to import the osm map data to local server. I want to clean up all the existing data and import fresh data. How can i do it? asked 09 Feb '16, 11:21  Reshma Maner edited 09 Feb '16, 11:47  aseerel4c26 ♦ |

If you run osm2pgsql without answered 09 Feb '16, 11:31  Frederik Ramm ♦ |
I executed following commands. But still map is not correctly displayed. Upper zoom level map is not displayed. On detailed zoom level only map shows.
sudo -u www-data osm2pgsql -C 2048 --slim --number-processes 4 india-latest.osm.pbf --cache-strategy sparse
touch /mod_tile/planet-import-complete
/etc/init.d/renderd restart
Path of my mod_tile directory is different than /var/lib. This path is mentioned in renderd.conf. Do I need to mention the path in osm2pgsql command also?
Also, after i execute above command, data of other countries which was renered previously should have been cleaned up. But it is not. It shows on map.
There are at least three places that "old data" can lurk. One is in the database; as Frederik has said osm2pgsql without --append will empty that and replace with whatever you're replacing it with.
The next is the metatile cache. If you look in "/var/lib/mod_tile" you'll see directories for each style you're displaying; if you haven't changed the name from "default" you'll see a directory called "default".
Below there you'll see subdirectories for each zoom level, perhaps something like this:
Below each subdirectory you'll eventually find ".meta" files such as:
To remove this cache, just delete these files.
Finally, there's the cache in your browser itself - usually a refresh will sort things out there.
