Add Spatial Location from document attributes for blank documents

Hello,

in ProjectWise we've got plenty blank documents (without files attached), each represents a geoTiff that will be scanned and inserted in future.

For each document several custom properties (Environment attributes) give Information about where the real document is archived, what's the content an what's the spatial boundary (MBR).

Now we try to add spatial locations to each of these documents to enhance search capabilities and to give better overview in our background map. Is there any way to generate the spatial location from Environment attributes (via API or Database stored methods)?

We're happy for any Information,

thank you in advance,

Maik
