This shows the list of the
projected CRSs included on the EPSG data base. It also allows the editing,
deletion and creation of new user CRS.
Each line of the list gathers the
CRS name and code separated by two points.
The drop down list of the section Data Source
allows EPSG data consultation to be switched to user data and vice versa.
The Search By section allows
the filtering of consultation data by Code, Name and Area. This latter option is only available for EPSG data. The zone
name (continent, country etc) must be specified in English. The string to be
searched must be entered in the box on the right and the 
button pressed. If searching by code, this
will only show the result if this same code can be found on the data base,
whilst in the search by name and area, this will show all the CRS whose name or
usage area contains the string entered.
By double clicking a CRS on the
list its properties are displayed, Datum, Projection Type, Projection Parameters, Area
of Use, Revision Date and Remarks.
