| | 18 | == Overview == |
| | 19 | |
| | 20 | This is a proposal to serialize FdoGeometryType_CurveString geometry into GML2 format. |
| | 21 | |
| | 22 | == Motivation == |
| | 23 | |
| | 24 | 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. |
| | 25 | |
| | 26 | == Proposed Solution == |
| | 27 | |
| | 28 | 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. |
| | 29 | |
| | 30 | '''NOTE:''' |
| | 31 | |
| | 32 | • The curve will have some attribute lost when serialize to gml:LineString. |
| | 33 | |
| | 34 | == Implications == |
| | 35 | |
| | 36 | In FdoGML212GeometrySerializer implement SerializeCurveString. |
| | 37 | |
| | 38 | == Test Plan == |
| | 39 | |
| | 40 | Tested by customer and it's acceptable. |
