Hi,
Minor steps have been made so far. Only two days of initial effort has been
put in so don't expect much :)
Changes made:
Geotools
- Modification in gt-jdbc-postgis to be able to get postgis data:
use ST_AsEWKB instead of ST_AsBinary because ST_AsBinary ony returns X,Y
removed force_2d from query
- Modification in gt-referencing:
added DirectPosition3D class
- couple of gml/geometry modifications in gt-main
- couple of modifications in gt-xsd-gml3
- couple of modifications in gt-xsd-api
JTS
- added getCoordDimensions function to geometry and implementors
- modified WKTWriter to be able to write 3d data
Geoserver
- temporary modification for WGS84 bounding box calculation when adding 3D
vector layers
I'll probably forget some changes that will appear when I'll do proper
source check.
Above modifications make it possible to get 3D GML data from a postgis
database using Geoserver.
Currently we only tested this with POINT in EPSG:7415 (Amersfoort RD new +
NAP).
We will also test LINESTRING and POLYGON pretty soon.
Best regards,
Sjoerd
