Coordinate Conversion
WOW has historically had a single-point ‘Lat/Lon ⇔ XY Calculator’ which converts
coordinates within the context of the OpenWorks project, i.e. between projected and
geographic coordinates using the project’s CRS. Version 5000.0.1.0 added the option to
use WGS84 as the geographic coordinate system, allowing for datum shifting.
New in version 5000.0.1.2 are generic coordinate conversion utilities that will convert
between any two cartographic reference systems (projected or geographic), provided the
conversion is allowed by the underlying Blue Marble conversion software. Datum shifting
is carried out automatically. The following have been added, illustrated further below:
• single-point conversion via WOW browser (on the OpenWorks project list page)
• crsids command line utility to list projected and basis CRSs
• crsConvert command line utility for single-point conversion
• fileCrsConvert command line utility for file-based conversions
• CrsConvert GUI for multiple point file-based conversions.
Utility crsids: lists project and basis CRS ID and name for all or a specified project. The
CRS IDs are required for use in crsConvert and fileCrsConvert.

Utility crsConvert: command-line single-point conversion between any two
cartographic reference systems (projected or geographic). Note the order of arguments:
either X Y or Lon Lat (as opposed to Lat Lon).
