+Instructions for generating vector contours for Jordan:
+1. Download SRTM 30m or Copernicus DEM GeoTIFF for Jordan bbox (29-34N, 34-40E).
+2. Generate 10m contours:
+   gdal_contour -a elevation -i 10.0 /tmp/jordan_dem.tif /tmp/jordan_contours.shp
+3. Import to PostGIS:
+   shp2pgsql -I -s 4326 -a /tmp/jordan_contours.shp jordan_contours | psql -U $POSTGRES_USER -d $POSTGRES_DB
+4. Update is_major flag:
+   UPDATE jordan_contours SET is_major = (MOD(elevation::int, 50) = 0);
