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.
