Hi Even, Thank you for your quick answer, We work with C#, and unfortunately, we didn’t find GDALDriverManager API.
Instead, we tried algorithm you proposed with OGR Driver.DeRegister()/Register() : this does not work, csv change is not taked into account (csv file seems to be cached) -- Jerome From: Even Rouault [mailto:even.roua...@spatialys.com] Sent: Friday, February 9, 2018 2:53 PM To: email@example.com Cc: Jerome Siot Subject: Re: [gdal-dev] S57 objects’ catalog reload Jerome, > > I would like to change the s57 objects’ catalog while running between two > open of datasources.

If your workflow is open dataset 1 work with it close dataset 1 change .csv file open dataset 2 work with it close dataset 2 then after "change .csv file", you could unload and reload the S57 driver so that the S57ClassRegistrar singleton gets destroyed and reloaded, with something like (untested): GDALDriverManager* poDM = GetGDALDriverManager(); GDALDriver* poDrv = poDM->GetDriverByName("S57"); poDM->DeregisterDriver(poDrv); delete poDrv; RegisterOGRS57(); If you need to operate on 2 simultaneously opened datasets with different .csv files, then changes would be needed in the S57 driver.
