Re: [gdal-dev] GDAL S57 "New Object"

[Damian Dixon]

The following is really for information...

New Object is an interesting one. It's used to extend the features
available in S-57 by the data provider without the need to modify the
standards (S-57 & S-52).

Normal a New Object is only created when there is a pressing need to
represent something new that is important to display. The only time I have
seen New Object is in test data.

The drawing instructions are normal embedded in the object itself rather
than being rules defined by the S-52 rendering tables. This means that
attributes may not be present.

So while you will be able to read the object, displaying it correctly may
not be so easy.

Regards
Damian

Jerome,

It looks like you spotted the issue. Would you mind submitting a patch with the 
new entry in 
the file ?

[gdal-dev] GDAL S57 "New Object"

[Jerome Siot]

Hi,
Implementing a program using gdal 2.0.1, I trap an exception on a 
GetNextFeature() call, on layer id 163 "NEW OBJECT", described on 
www.s-57.com.
As a first idea, I read gdal/gdal/data/s57objectclasses.csv (from 
https://github.com/OSGeo/gdal/commits/trunk/gdal/data/s57objectclasses.csv) => 
this file has no description for "New Object"

Any idea ?
