Setting Co-ordinate Reference System

The NSTA requires the spatial definition of both the survey polygon and the file headers to match and to be assigned for the seismic project.

Data Managers will not be able to load data to an existing seismic Project ID if the Co-ordinate Reference System (CRS) is not assigned.  To check if the CRS has been set, launch the Suggest Edits pop-up UI. If the CRS value is 'false', it will need to be set before data can be loaded to the project.

Data Managers can now assign the CRS for their existing seismic projects prior to loading data. (New projects made in the NDR have a CRS assigned as part of the creation form). There are sixteen specific CRS definitions that the NSTA will accept data to be referenced to, each of these has been summarised in the “Form and Manner” document and have been configured into the NDR.

To set the CRS for an existing seismic project, from the Project ID Menu, the Data Manager can launch the Suggest Edits pop-up UI and simply choose the required CRS from a drop-down menu, then click the green Submit Edits button to submit the change.

Some changes won’t be reflected immediately in the interface, so if you are planning to report seismic data please check and set the CRS in advance. 

As with other metadata edits, comments should not be added unless the file requires some form of intervention from the NSTA. Generally this will not be the case for CRS edits.
