[mapserver-users] KML reading through OGR

[Schylberg Lars]

The OGR style is the variable that is returned in the variable that is casted.
Please look at the Layer definitions that I sent yesterday in the mapfile example.


DATA "SELECT Name as NAME, CAST(OGR_STYLE AS character(32)) AS STYLE FROM 'Fibertech solution' WHERE OGR_GEOMETRY='LINESTRING'"

CLASSITEM "STYLE"

LABELITEM "NAME"



CLASS

     EXPRESSION "@msn_ylw-pushpin4"


That is the STYLE value used in the CLASSITEM expression.

The description is shown in the label that uses the labelitem.  Also shown in the mapfile example yesterday.


If You only want to get the features with the style ‘@msn_ylw-pushpin4' with ogrinfo you should write it like this:

ogrinfo -ro doc_test.kml \
-sql "SELECT *, CAST(OGR_STYLE AS character(255)) AS STYLE FROM 'Fibertech solution' \
WHERE OGR_GEOMETRY='LINESTRING' AND OGR_STYLE='@msn_ylw-pushpin4'" –al

That returns the geometry and variables according to this criteria, i.e. only lines and specific style.

But I guess that You most likely would like to do this filtering in the Class section of the mapfile and not in the DATA statement.

Hi,

I am unable to get the Styleurl using Ogrinfo. I am trying the command
ogrinfo -al doc_test.kml -where "ogr_style='@msn_ylw-pushpin4'"

but the result is
Layer name: Fibertech solution
Geometry: 3D Unknown (any)
Feature Count: 0
Layer SRS WKT:
GEOGCS["WGS 84",
    DATUM["WGS_1984",
        SPHEROID["WGS 84",6378137,298.257223563,
            AUTHORITY["EPSG","7030"]],
        TOWGS84[0,0,0,0,0,0,0],
        AUTHORITY["EPSG","6326"]],
    PRIMEM["Greenwich",0,
        AUTHORITY["EPSG","8901"]],
    UNIT["degree",0.0174532925199433,
        AUTHORITY["EPSG","9108"]],
    AUTHORITY["EPSG","4326"]]
Name: String (0.0)
Description: String (0.0)



Also i want to show the description of placemark on map.

Thanks!
