[gdal-dev] ogr2ogr problem converting UK Ordnance Survey MasterMap

[Jez Walters]

Frank,


Thanks for looking in to this!  I've just repeated the problem with the Ordnance Survey sample MasterMap, which is available from here:

http://www.ordnancesurvey.co.uk/oswebsite/products/innovations/sampledata/OSMasterMap_Topo/58116-SX9192-2c1.gz

I tried converting the above GML to ESRI shapefile using the following command:

ogr2ogr SX9192 58116-SX9192-2c1

One thing I've noticed is that the schema referenced in the GML (http://www.ordnancesurvey.co.uk/xml/schema/v7/OSDNFFeatures.xsd) defines a number of elements called "complexType".  The "complexType" element with a name of "CartographicTextType" is defined like this:

<complexType name="CartographicTextType">
	<complexContent>
		<extension base="osgb:AbstractFeatureType">
			<sequence>
				<element name="anchorPoint" type="gml:PointPropertyType"/>
				<element name="changeHistory" type="osgb:changeHistoryType" maxOccurs="unbounded"/>
				<element name="descriptiveGroup" type="osgb:descriptiveGroupType" minOccurs="0" maxOccurs="unbounded"/>
				<element name="descriptiveTerm" type="string" minOccurs="0" maxOccurs="unbounded"/>
				<element name="make" type="osgb:makeType" minOccurs="0"/>
				<element name="physicalLevel" type="osgb:physicalLevelType"/>
				<element name="physicalPresence" type="osgb:physicalPresenceType" minOccurs="0"/>
				<element name="textRendering" type="osgb:textRenderingType"/>
				<element name="textString" type="string"/>
			</sequence>
		</extension>
	</complexContent>
</complexType>

>From which I conclude that the orientation is actually part of the "textRendering" element.  I'm sure I'm on to something with this, but I'm not sure how to proceed from here!


Warm regards,


Jez

Jez,

Can you provide a mastermap file I can test with?

Best regards,
