Question

I have to create a program for converting ESRI Shapefiles into OS VectorMap Local GMLs. I’m looking for some information for my problem… I tried to use documentation from both sites:

• ESRI Shapefile documentation
• OS VectorMap Local documentation

I use ESRI Shapefile Reader library and it works fine. I can read my *.shp files. The problem is I don’t know where I should get featureCode from…

  <osgb:lineMember>
    <osgb:Line fid="ID_864">
      <osgb:featureCode>15600</osgb:featureCode>
      <osgb:featureDescription>Water Feature</osgb:featureDescription>
      <osgb:polyline>
        <gml:LineString srsName="osgb:BNG">
          <gml:coordinates>405513.50,408701.00 405514.01,408707.15 405514.50,408711.50</gml:coordinates>
        </gml:LineString>
      </osgb:polyline>
    </osgb:Line>
  </osgb:lineMember>

ESRI Shapefiles contain only coordinates, so I don’t know what its feature code is…

The 2nd thing is <osgb:textMember> tag. WTF is a textMember? Which one shape type in ESRI Shapefile?

Thanks in advance for any help!

[edit]
Or maybe you know some library/program for doing convertion like this? It’d be a great solution aswell:)

The answer to your conversion question is easy enough – GDAL can convert from shp -> VML, using ogr2ogr. See the comments on this question for syntax.
