# PMTiles Generation Script for GeoEdu Service
|
||||
# ============================================
|
||||
#
|
||||
# Generiert PMTiles Vector Tiles aus PostGIS OSM Daten
|
||||
# Verwendet tippecanoe fuer die Tile-Generierung
|
||||
#
|
||||
# Voraussetzungen:
|
||||
# - OSM Daten in PostGIS importiert
|
||||
# - tippecanoe installiert
|
||||
# - ogr2ogr (GDAL) installiert
|
||||
#
|
||||
# Nutzung:
|
||||
# ./generate_tiles.sh [--min-zoom 0] [--max-zoom 14]
|
