Description (last modified by )
Dutch inland ENCs are encoded in a slightly different way than most (maritime) ENCs. They are, however, compliant with the IHO S57 3.1 specification. The difference is that in a vector record (section 7.7 of the S57 spec), a line or polygon feature can be encoded in more than one way: one SG2D record with repeating rows of coordinates or a repeating series of SG2D records with one row of coordinates (or even a combination thereof). The current (1.7.3) driver only supports the former encoding. This patch adds support for both encodings. Tested against inland ENCs at ftp://sdg.ivs90.nl/ENC/ and several maritime ENCs
