Frequently-used geodetic CRS and datum that are guaranteed to be available in SIS.
Some (not all) objects defined in this enumeration are equivalent to objects defined
in the EPSG geodetic dataset. In such case there is a choice:
- If the EPSG dataset is installed, then the methods in this enumeration are effectively shortcuts for object definitions in the EPSG database.
- If there is no EPSG database available, or if the query failed, or if there is no EPSG definition
for an object, then
CommonCRS
fallbacks on hard-coded values with minimal information. The identifier associated to the returned object should be interpreted as "see that EPSG code for more complete definition".
null
.
The definitions used as fallbacks are available in public sources
and do not include EPSG metadata except the identifier.
If the EPSG geodetic dataset has been used, the authority title
will be something like "EPSG geodetic dataset", otherwise it will be "Subset of EPSG".
Referencing objects are cached after creation. Invoking the same method on the same CommonCRS
instance twice will return the same IdentifiedObject
instance, unless the internal cache has been cleared
(e.g. the application is running in a container environment and some modules have been installed or uninstalled).

universal
public org.opengis.referencing.crs.ProjectedCRS universal(double latitude, double longitude) Returns a Universal Transverse Mercator (UTM) or a Universal Polar Stereographic (UPS) projection for the zone containing the given point. There is a total of 120 UTM zones, with 60 zones in the North hemisphere and 60 zones in the South hemisphere. The projection zone is determined from the arguments as below:- If the latitude argument is less than 80°S or equal or greater than 84°N, then a Universal Polar Stereographic projection is created.
- Otherwise a Universal Transverse Mercator projection is created as below:
- The sign of the latitude argument determines the hemisphere: North for positive latitudes (including positive zero) or South for negative latitudes (including negative zero). The latitude magnitude is ignored, except for the special cases documented below and for ensuring that the latitude is inside the [-90 … 90]° range.
- The value of the longitude argument determines the 6°-width zone, numbered from 1 for the zone starting at 180°W up to 60 for the zone finishing at 180°E. Longitudes outside the [-180 … 180]° range will be rolled as needed before to compute the zone.
- Calculation of UTM zone involves two special cases (if those special cases are not desired,
they can be avoided by making sure that the given latitude is below 56°N):
- Between 56°N and 64°N, zone 32 is widened to 9° (at the expense of zone 31) to accommodate southwest Norway.
- Between 72°N and 84°N, zones 33 and 35 are widened to 12° to accommodate Svalbard. To compensate for these 12° wide zones, zones 31 and 37 are widened to 9° and zones 32, 34, and 36 are eliminated.
Tip: for "straight" UTM zone calculation without any special case (neither Norway, Svalbard or Universal Polar Stereographic projection), one can replace theThe map projection uses the following parameters:latitude
argument byMath.signum(latitude)

argument byzone * 6 - 183
