Galdos has made a significant enhancement to its CRS Registry application through the addition of the capability to export a coordinate reference system (CRS) in the Well Known Text (WKT) format.
The enhancement was completed to support the International Association of Oil & Gas Producers (IOGP) EPSG Geodetic Parameter Registry (www.epsg-registry.org ). The IOGP recently announced (http://www.directionsmag.com/pressreleases/iogp-releases-coordinate-reference-system-definitions-in-well-known-text-fo/427321 ) that the latest version of their online registry now includes the facility to export coordinate reference systems (CRS) and coordinate transformation definitions in well-known text (WKT). The EPSG Geodetic Parameter Registry is a custom implementation of the Galdos CRS Registry.
WKT is a format that conforms to ISO 19162 and was developed by the Open Geospatial Consortium (OGC) as a compact representation of geometric objects that is both machine-readable and human-readable. Geography Mark-up Language (GML) is still the preferred format for CRS definitions, and remains as the format in which the data is stored. GML retains all the metadata about the source and applicability of the CRSs and coordinate transformations. However, WKT offers a format that is succinct and which includes just the critical elements of a CRS definition.
For more information about how WKT works in the CRS Registry, read the “CRS Registry Supports Well-Known Text ” post in Ron Lake’s Blog.
