WGS 84 / UTM zone 48S

EPSG:32748 is WGS 84 / UTM zone 48S, a Transverse Mercator projection in metres on the WGS 84 ellipsoid. Its central meridian is 105° E, the latitude of origin is 0°, the scale factor is 0.9996, the false easting is 500,000 m and the false northing is 10,000,000 m.

The definition bundled with mapverter gives an area of use from 102° to 108° E and 80° S to the equator. Jakarta lies in this zone, and the point at 106.8° E, 6.2° S, in the city, is about x = 699,163 m and y = 9,314,349 m.

Zones and hemispheres in Indonesia

Indonesia spans several UTM zones and both hemispheres, so EPSG:32748 is not a single CRS for the whole country. DGN95 and SRGI2013 are separate reference systems and must not be relabelled WGS 84 without checking the source.

How mapverter handles EPSG:32748

  • A .prj is matched by its EPSG code or by its projection parameters, so the ESRI-style name WGS_1984_UTM_Zone_48S is recognized as well.
  • Without a .prj, the Indonesian interface offers EPSG:32748 first among the candidates that fit the data. Other UTM zones remain possible candidates. The English interface does not suggest it, so search for 32748 by EPSG code in the coordinate system picker, or click your area on the map to add its UTM zone.
  • This page presets EPSG:32748 as the target for SHP and CSV output. KML, KMZ, GeoJSON and GPX always use WGS 84 longitude and latitude.

Frequently asked questions

What does the S in EPSG:32748 mean?
It marks the southern-hemisphere variant, which adds a false northing of 10,000,000 m. EPSG:32648 is the northern variant of the same zone on WGS 84.
Can I use this code everywhere in Indonesia?
No. Select the zone and hemisphere of the source dataset. The country extends across several zones.
Why can multiple UTM candidates look plausible?
Different zones use the same false easting and similar coordinate ranges. Check the source metadata and the preview location.
Can I keep EPSG:32748 in KML?
No. KML uses WGS 84 longitude and latitude. Choose SHP or CSV to keep UTM coordinates.
