Overview
Workflows (experimental)
This is work in progress. The plan is to put everything in a single batch file.
0. Prepare software and config data
- Install software: OGR, SpatiaLite, TileMill
- Get config data, e.g. modified osmconf.ini
- Prepare clip boundary, e.g. liechtenstein_schloss_bbox.geojson
1. Download, convert and clip OSM data (PBF file in, SQLite/SpatiaLite file out):
> ogr2ogr -f "SQLite" liechtenstein3.sqlite /vsicurl/http://download.geofabrik.de/europe/liechtenstein-latest.osm.pbf -dsco SPATIALITE=YES -skipfailures -progress -overwrite --config OSM_CONFIG_FILE osmconf.ini -gt 65536 -clipsrc liechtenstein_schloss_bbox.geojson -clipsrclayer OGRGeoJSON -nlt PROMOTE_TO_MULTI
2a. Enhance SQLite dataset by shuffling geo objects around (using Spatialite, SQLite file in/out)
- Eventually convert multilinestring to linestring if TileMill/Mapnik can't handle multipolygons.
- Convert Polygons to Points and add them to points as POIs.
2b. Do some other preprocessing like line smoothing of streets using preprocessing tools (Python, SQLite file in/out)
- tbd.
3. Style data using TileMill
4. Publish map
