[MapProxy] Re: Refresh existing tiles

[Johannes Weskamm]

Hi,

Here you can find the php-script for generating poylgons from a tile-list:

More information in the header.
If you prefer other programming languages, also have a look at the header.


@Oliver: If you want to include it in the mapproxy trunk, you got my 
permission :-)

> Can you share this load-next script part?
The important part is this one:

$OSM2PGSQL --append --slim --bbox "87,42,120,53" -e 0-18 -o expire.list 
--cache 1024 --merc --prefix $PREFIX --style $STYLE --host $HOST 
--database $DB --username $USER --hstore --verbose "$CURRENT" 1>&2 2> 
"$PSQLLOG"

> You reseed only existing tiles, I guess, not generating new ones? How it is configured in seed.yaml to get this? This is something I may need for layout-driven update also.
I have a complete cache. On update, i first make a MapProxy-cleanup, 
then i make a seed, both with the polygons from the database. Of course 
everything is scripted to do this automatically.
My seed.yaml looks like this:

seeds:
   mongolia:
     caches: [osm_cache]
     grids: [mongolia_grid]
     coverages: [mongolia]
     levels:
       from: 0
       to: 18

cleanups:
   clean1:
     caches: [osm_cache]
     grids: [mongolia_grid]
     coverages: [mongolia_cleanup]
     levels:
       from: 3
       to: 18
     remove_before:
        time: 1969-01-31T12:00:00

coverages:
   mongolia:
     ogr_datasource: '../world_boundaries_m.shp'
     ogr_where: 'CNTRY_NAME = "Mongolia"'
     ogr_srs: 'EPSG:3395'
   mongolia_cleanup:
     ogr_datasource: "PG: dbname='osm' host='localhost' user='user' 
password='pass'"
     ogr_where: "select the_geom from updatepolygons"
     ogr_srs: 'EPSG:900913'
