coordsys.db - Located directly under the root FME installation folder, this file contains the names and descriptions
of all predefined coordinate systems. It is typically a subset of all
the definitions that are known to FME. That is, there may be additional
systems defined in the coordsys file that are not in coordsys.db
because the systems have been deprecated, or for some other reason. Any systems
defined in LocalCoordSysDefs.fme, MyCoordSysDefs.fme or as an FME Shared
Resource are automatically added to FME and do not need an entry in this
file. LocalCoordSysDefs.fme,
and resides in .
It LocalCoordSysDefs.fme - Located in the Reproject subfolder under the FME installation folder, this file contains
overrides to the standard coordinate systems (and related parameters)
defined by FME, and is made available to each FME session. It contains a series of COORDINATE_SYSTEM_DEF,
DATUM_DEF, ELLIPSOID_DEF, and UNIT_DEF lines that define additional, site-specific
coordinate systems. The built-in definitions for any coordinate system/datum/ellipsoid
may be overridden by this
file. The structure of LocalCoordSysDefs.fme is the same as MyCoordSysDefs.fme,
and its contents can be used as a template for new custom coordinate systems. You should NOT edit LocalCoordSysDefs.fme,
because it is overwritten each time FME is installed.
MyCoordSysDefs.fme - Located
in the Reproject folder, this file contains custom coordinate system definitions.WARNING: Although FME does not overwrite MyCoordSysDefs.fme during
installation, it is always good practice to back up this file. Although you should not edit LocalCoordSysDefs.fme
or coordsys.db , note that FME overwrites these files during installation.
Therefore, you should back up these files if you made any changes.
