  • Ticket #3881 – Description

    initial v1  
    1 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 can be encoded in two ways:
    2 one SG2D record with repeating rows or a repeating series of SG2D with one row (or even a combination thereof).[[BR]]
    3 The current (1.7.3) driver only supports the former encoding. This patch adds support for the both encodings.[[BR]]

     2one SG2D record with repeating rows of coordinates or a repeating series of SG2D records with one row of coordinates (or even a combination thereof).
     3The current (1.7.3) driver only supports the former encoding. This patch adds support for both encodings.
