Hi,
I find one problem I didn't notice before. Since each borehole corresponds to
one point and in Oracle, the spatial value is like "(2001, , (275730, 234970,
), , )" (I only define one X, Y),
However, the output is like
<sa:shape>
<gml:LineString>
<gml:posList>163410.0 264500.0 163410.0 264500.0</gml:posList>
</gml:LineString>
</sa:shape>
There are two X, Y. Why?
Thanks,
Ying

Subject: RE: [Geoserver-users] About gsml:Borehole again
Hi Ying, to answer your questions :
I asked this question in May, could I ask whether <sa:shape>
has been improved to support 3-dimension?
AND how to add 'srsName',
'srsDimension' to gml:LineString as above?
No, geoserver do not support 3D coordinate yet.
(Someone please correct me if it does now...)
To get the srsName, srsDimension for LineString, in
Oracle, you need to add the linestring column to USER_SDO_GEOM_METADATA table,
e.g. :
INSERT
INTO USER_SDO_GEOM_METADATA VALUES
(table_name,column_name,diminfo,srid);
e.g.
INSERT INTO USER_SDO_GEOM_METADATA VALUES (
'SITE',
'GEODETIC_POINT',
MDSYS.SDO_DIM_ARRAY(
MDSYS.SDO_DIM_ELEMENT('longitude', -180, 180,
0.000001),
MDSYS.SDO_DIM_ELEMENT('latitude', -90, 90, 0.000001)
),
4326);
GeoServer will encode the srsName and srsDimension base
on the SRID.
For your
second question on 1D mapping, I don't think GeoServer support 1D coordinate at
the moment as well.

Florence

Subject: [Geoserver-users] About
gsml:Borehole again
Hi,
I come back to gsml:borehole again. Now, the GeoServer
runs very well except for several small questions. Thanks very much.
1.
About gsml:Borehole/sa:shape
What I want is
like
<sa:shape>
<gml:LineString
gml:id="bh.TR34SWBJ90.shape"
srsName="urn:ogc:def:crs:EPSG:6.15:7405"
srsDimension="3">
<gml:pos>630400 0141150
29.5</gml:pos>
<gml:pos>630400 0141150
74.5</gml:pos>
</gml:LineString>
</sa:shape>
So in
<gml:pos>, it should be like 'X Y Depth'.
In mapping file, I
define,
<AttributeMapping>
<targetAttribute>gsml:Borehole/sa:shape</targetAttribute>
<sourceExpression>
<OCQL>GEOM</OCQL>
</sourceExpression>
</AttributeMapping>
where
'GEOM' is a Oracle spatial field in a table. But I can only get
<sa:shape>
<gml:LineString>
<gml:posList>163410.0 264500.0 163410.0
264500.0</gml:posList>
</gml:LineString>
</sa:shape>
It
seems GeoServer still doesn't support 3-dimension.
I asked this
question in May, could I ask whether <sa:shape> has been improved to
support 3-dimension?
AND how to add 'srsName', 'srsDimension' to
gml:LineString as above?
2. About gsml:shape in
gsml:MappedInterval
If I encode a borehole log as MappedIntervals, then
in gsml:MappedInterval, I need to define gsml:shape. What I want is
<gsml:shape>
<gml:LineString
srsName="bh.TR34SWBJ90.shape"
srsDimension="1">
<gml:pos>0</gml:pos>
<gml:pos>1.0</gml:pos>
</gml:LineString>
</gsml:shape>
as Above, it define the starting depth to the end
depth from 0 to 1.0, which is one layer of a borehole.
Could I ask how
to define this in the mapping? Should I define a new Oracle spatial field and
use something
like,
<AttributeMapping>
<targetAttribute>gsml:MappedInterval/sa:shape</targetAttribute>
<sourceExpression>
<OCQL>GDEPTH</OCQL>
</sourceExpression>
</AttributeMapping>
??????????????? Or there is better
way???
Meanwhile, how to add srsDimension to
gml:LineString?
Thanks very much for your
help,
Ying
