Projection page¶
The projection property page allows you to change the projection of a layer if it has been loaded with the incorrect projection.
Standard CRS¶
This tab allows you to explore the standard coordiante reference systems listed by:
- EPSG codes
- OGC codes
These codes are used to look up an exhaustive formal definition of a coordinate reference system. By describing your data in this manner uDig can both work faster and with greater accuracy.
Custom CRS¶
You can supply your own custom coordinate reference system using the “Well Known Text” format.
Note
You can switch to this tab to review a “Standard CRS* definition using WKT as a quick informal summary; or as a starting point for your own custom definition.
