This adds a unit test that tests weather the projection (spatial reference)
is being added inside the geometry object when writing features as
esriJson.
The WFS transaction failed if the srsDimension was not present on the
geometries.
Unit tests have been changed to accomodate the srsDimension attribute.
Contrary to Mapserver, Geoserver sets the srsDimension attribute on
the child of the geometry node, not on the points list.
This fix searches that node as well.
A small unit test was also added.
Some WFS servers like tinyOWS require the feature prefix to be in the
feature type for the feature to be found (eg `prefix:layer`).
The problem was, the prefix was always added to the feature type which
gave us a type name like `prefix:prefix:feature` or
`feature:prefix:feature`. The requests were then rejected by the WFS
server.
We now check if the feature type starts with the prefix. If it does, we
don't append it again. If it doesn't we do.
The code used to rely on the dimension. However, the dimension can only
be read from a GML3 document. This caused, for 3D geometries:
- An assertion error to be raised since the flatCoordinates list
contains more than 3 elements: "Assertion failed: flatCoordinates should
have a length of 3" The value of flatCoordinates for a 3D point was
something like `[2586394, 1232407, 0, 731, NaN, 0]`
- The value of the Z coordinates to be incorrect and always set to 0
This patch simplifies and correct the parsing of the coordinates:
- Don't parse groups of coords and the coordonates at the same time.
- Detect the dimension for the coordinates.
- If the Z coordinate exists, its value is used, otherwise, we use 0.
- Correct the presentation of test data to make it work with the new
parser.
- Add a test for a 3D point.
- Add a version property to olx.format.WFSWriteTransactionOptions to set
the WFS protocol version to use
- Use the specified version to use the correct schema and version in the
GML request
- Use the version to select the proper GML serializer
