HI Paul, If this is just a one-off search you can use the EPSG registry at: http://www.epsg-registry.org/
E.g. for your query you could enter nad83 as the name, Projected CRS as type, and the coords of a bounding box that include the parallel You can also do searches within GeoTools. This page in the users' guide shows one approach: http://docs.codehaus.org/display/GEOTDOC/01+CRS+Helper+Class#01CRSHelperClass-SearchingforaCoordinateReferenceSystem That example uses the CRS helper class and is looking for a single EPSG code with this statement: String code = CRS.lookupIdentifier( example, true ); To get the set of call EPSG codes that match your known parameters I think you would either need to query the local epsg database directly (e.g. the HSQL database if you are using gt-epsg-hsql module with your project) or get down and dirty in the referencing API, constructing IdentifiedObject instances based on your known parameters and submitting these to the referencing finder classes. Unfortunately the CRS helper class doesn't help with that at present. If you need to go down this track, let us know. Of course, if we're lucky, someone else here may be able to point to other, easier approaches.
