Opening VPF DNC's Notes in GDAL?

I use a compiled version of GDAL, including OGDI lib :

  • GDAL 2.0.1
  • OGDI 3.1.6

I can open DNC Charts and retrieve layers / features. DNC Charts use VPF format.

Problem : I’m not able to retrieve notes which can be found in NOTES.RAT and NOTES.NJT, like explained in this VPF specification :

VECTOR PRODUCT FORMAT (VPF) products General Specification

3.16.4.2.1.1 Notes related attribute tables

Have you got any idea about this question ?

Solution

  • After discussion with the OGDI lib developer, there is no way to get notes using OGDI (for the moment). You must decode binary files (notes.rat, notes.njt) according to VPF specification : VECTOR PRODUCT FORMAT (VPF) products General Specification
