Stealth offline map: Romania

An offline map region for the Stealth iOS app (private, on-device). The app downloads these files once and draws the map, searches places and reads elevation entirely on the iPhone.

How it was built

The scripts are in the Stealth repository, under native/Tools/maps/:

pmtiles extract https://build.protomaps.com/20261025.pmtiles base.pmtiles --region=romania.geojson --maxzoom=14
pmtiles extract https://download.mapterhorn.com/planet.pmtiles terrain.pmtiles --region=romania.geojson --maxzoom=11
build_trails.py romania-latest.osm.pbf trails.geojsonseq
tippecanoe -o trails.pmtiles -Z8 -z14 --drop-densest-as-needed --extend-zooms-if-still-dropping --no-tile-size-limit trails.geojsonseq
build_places.py romania-latest.osm.pbf places.sqlite
build_contours.py terrain.pmtiles contours.geojsonseq
tippecanoe -o contours.pmtiles -l contours -Z10 -z13 -y ele -y idx --no-tile-size-limit --no-feature-limit contours.geojsonseq

The boundary is Geofabrik's romania.poly. Under the ODbL, trails.pmtiles and places.sqlite are derivative databases and are offered under the same licence.

Trail difficulty and track grades come from OpenStreetMap volunteers. They can be missing or out of date, so always check local conditions.
