[OpenLayers-Users] KML/GML from text file?

[Burgholzer,Robert]

Robert,

Thanks much for your reply.  While I did not go the route of manually
defining my GML based on your example, what your example did was jog my
memory: "where have I seen that before???" - mapserver WFS output of
course.  Since I have mapserver on my system, configured for WFS, I
simply loaded the WFS layer in an open layers shell, then copied the GET
for the layer in question out of the Firebug Console (thanks to a post
by Arnd Wipperman on an earlier thread), and voila, I had myself a
properly formatted GML file.

 

What's the use if I already have mapserver?  Well, I have a fairly
restrictive internet setup here, so I am not able to hit any of my
mapserv installs, so I am experimenting with an entirely OL approach,
since that is javascript and runs on the client. So far, I am very
encouraged!

 

Thanks again to Robert and Arnd for kicking the knowledge.

Yes, managed to get it to work. I have some Java code that pulls a
geometry out of a database (SDE) and writes it to a local file system
file. Seems OL is fairly fussy about the structure of the GML file.
Anyway, here is the OL code:

 

var fbnd = new OpenLayers.Layer.GML("Farm boundary", "./farmfiles/" +
farmid + ".xml", {style: farm_style});
                    map.addLayer(fbnd);

 

And here is a sample GML (I experimented with GML structure using one of
the OL examples that writes out GML to a text box, then emulated that):

 

<wfs:FeatureCollection xmlns:wfs="http://www.opengis.net/wfs">
  <gml:featureMember xmlns:gml="http://www.opengis.net/gml">
    <feature:features
xmlns:feature="http://mapserver.gis.umn.edu/mapserver"
fid="OpenLayers.Feature.Vector">
      <feature:geometry>
        <gml:Polygon>
          <gml:outerBoundaryIs>
            <gml:LinearRing>
              <gml:coordinates decimal="." cs=", " ts=" ">
                1821412.509, 5534791.015 1821458.847, 5534735.59
1821598.037, 5534849.028 1821614.701, 5534862.607 1821673.566,
5534910.58 1821659.449, 5534927.465 1821655.449, 5534932.249
1821627.218, 5534966.016 1821412.509, 5534791.015
              </gml:coordinates>
            </gml:LinearRing>
          </gml:outerBoundaryIs>
        </gml:Polygon>
      </feature:geometry>
    </feature:features>
  </gml:featureMember>
</wfs:FeatureCollection>

Kind regads,

Has anyone loaded a simple KML/GML layer from a local text file?  Maybe
this is trivial . 

Thanks!
