Overview ¶

This is a proposal to serialize FdoGeometryType_CurveString geometry into GML2 format.

Motivation ¶

FdoGeometryType_CurveString is a geometry type in customer's data. When publishing this data to WFS in GML2 format, it ends up with exception. It's expected this can work properly.

Proposed Solution ¶

GML schemes are defined here ​http://schemas.opengis.net/gml/. Unlike GML3 which uses gml:ArcString to represent curve, GML2 does not have type for gml:ArcString. A solution is to use gml:LineString to simulate curve.

NOTE:

• The curve will have some attribute lost when serialize to gml:LineString.

Implications ¶

In FdoGML212GeometrySerializer implement SerializeCurveString.

Test Plan ¶

Tested by customer and it's acceptable.
