EPSG Database at Ocean - Coordinate Conversions

Map conversion is the process of changing the map grid coordinates (usually, but not always, Eastings & Northings) of a Projected Coordinate Reference System to its corresponding geographical coordinates (Latitude & Longitude) or vice versa. Select the Projected Coordinate Reference System to use. You may first reduce the number of systems from which selection is made by filtering the dataset by CRS name or geographic area name
There are a huge number of projected coordinate reference systems. You may filter them by:
Name is like
Geographical area is like
Projection type
Include deprecated CRSs
