Overview
Workflows (experimental)
This is work in progress. The plan is to put everything in a single batch file.
Step 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
Step 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
Step 2a. Enhance SQLite dataset by shuffling geo objects around (using Spatialite, SQLite file in/out)
- Convert Polygons to Points and add them to points as POIs.
- Eventually convert multilinestring to linestring (can TileMill/Mapnik and QGIS handle multilinestrings/multipolygons?).
Step 2b. Do some other preprocessing using preprocessing tools (Python, SQLite file in/out)
- line smoothing of streets
- tbd.
Step 3. Style data using TileMill
- See CartoCSS and TileMill
Step 4. Publish map on the web
- See e.g. Geovisualisierung
