About EPSG:32633

EPSG:32633 is the Universal Transverse Mercator Zone 33N projection on the WGS 84 datum. UTM 33N runs from 12°E to 18°E and covers Norway, Sweden, Poland, Slovakia, Hungary, Italy (eastern), the western Balkans, Libya and central Africa. Eastings are offset by 500,000 m so values are always positive within the zone; northings count from the equator.

UTM is the workhorse of any project needing metric coordinates over a large area without the high distortion of Web Mercator: distortion stays below 1/2500 (40 cm per kilometre) within the central 6° band. Beyond ±3° from the central meridian, prefer the adjacent zone (EPSG:32632 or EPSG:32634).

Common use cases

  • GPS surveys and field data collection
  • Topographic mapping in zone 33N coverage
  • Engineering and construction planning
  • Defence / NATO spatial data (which standardises on UTM/MGRS)

Frequently asked questions

Should I use UTM Zone 33N or Web Mercator (EPSG:3857)?
UTM gives metric coordinates with accurate distance and area (within its zone). Web Mercator is for tile alignment with online basemaps. Use UTM for analysis, Web Mercator for display.
What is the proj4 string for EPSG:32633?
The proj4 definition for EPSG:32633 is: +proj=utm +zone=33 +datum=WGS84 +units=m +no_defs +type=crs
Where is EPSG:32633 used?
EPSG:32633 (WGS 84 / UTM zone 33N) is defined for the area: World - N hemisphere - 12°E to 18°E - by country.
