2.1. DTECT_DATA: the data access point

Installation of OpendTect usually means making available a base directory from which the project data can be reached. The location of this directory can be set in the user's environment as DTECT_DATA, although, especially on Windows, this will be done 'behind the scenes' through a user setting ('Default DATA directory'). Anyway, the DTECT_DATA directory must be:

reachable from every machine that needs to access the data
accessible for the users for read/write

When users create a new project (known as 'Survey' in OpendTect), they can choose to locate the project directory on another disk than the $DTECT_DATA directory. In that case, OpendTect will locate the directory on the specified location and put a link in the $DTECT_DATA directory. Therefore, this directory does not necessarily have to have a lot of disk storage available.

The directory structure is as follows:
