Hi,
Here is a demo script which finds route from the service or yournavigation.org.
Save the following code into lib\ext\BeanTools, draw one or more lines with
OpenJUMP by using EPSG:4326 system, run the tool and copy the URLs from the
result window into browser and you will get the routes in KML format. Script
creates a request which follows the YOURS syntax
http://wiki.openstreetmap.org/wiki/YOURS and it is simple to modify to use
other YOURS parameters. I also made another version which is getting routes
from the service of the Helsinki Region Traffic and it works fine too.
With a little bit of work it should be possible to make an OpenJUMP routing
service plugin. Creating a request is easy but a very good plugin should be
able to handle coordinate conversions between OJ project coordinate system and
the one used by the routing service. And then OpenJUMP should be able to parse
the returning route which is typically in GPX or KML format. However, I tested
also a workaround by using GDAL in between. OpenJUMP can create a ogr2ogr
request and ogr2ogr can save the result as a shapefile and possibly converted
into another projection.
Get_YOURS_Route.bsh
==============
{
import com.vividsolutions.jts.geom.*;
import com.vividsolutions.jump.feature.*;
import com.vividsolutions.jump.geom.EnvelopeUtil;
import com.vividsolutions.jump.workbench.model.*;
htmlFrame = wc.workbench.frame.outputFrame;
htmlFrame.createNewDocument();
htmlFrame.setTitle("Output for gdal_translate");
fc =
wc.getLayerNamePanel().getSelectedLayers()[0].getFeatureCollectionWrapper();
int j=1;
for (Iterator i = fc.getFeatures().iterator(); i.hasNext();) {
Feature feature = (Feature) i.next();
LineString lineString = (LineString)feature.getGeometry();
htmlFrame.addText("http://www.yournavigation.org/api/1.0/gosmore.php?format=kml&flat=";
+lineString.getStartPoint().getY()+"&flon="
+lineString.getStartPoint().getX()+"&tlat="
+lineString.getEndPoint().getY()+"&tlon="
+lineString.getEndPoint().getX()
+"&v=motorcar"
+"&fast=1"
+"&layer=mapnik");
j++;
}
wc.workbench.frame.flash(htmlFrame);
htmlFrame.surface();
}
With small modifications the script works with the routing service of the
Helsinki Region Traffic. Coordinates must be in EPSG:2392 system. Can be tested
for example with LINESTRING (2538008.7818696885 6679830.130311615,
2538096.0339943343 6679899.818696884)
htmlFrame.addText("\"http://pk.hsl.fi/getroute/?format=gpx&profile=kleroweighted&from=location*Koordinaatti[";
+lineString.getStartPoint().getX()+", "
+lineString.getStartPoint().getY()+"]"
+"*"+lineString.getStartPoint().getX()
+"*"+lineString.getStartPoint().getY()
+"&to=location*Koordinaatti["
+lineString.getEndPoint().getX()+", "
+lineString.getEndPoint().getY()+"]"
+"*"+lineString.getEndPoint().getX()
+"*"+lineString.getEndPoint().getY()
+"\"" );

Coordinate[] cc = geometry.getCoordinates();

y_start = cc[0].y;
x_end = cc[cc.length-1].x;
y_end = cc[cc.length-1].y;

LineString lineString = (LineString)feature.getGeometry();
x_start = lineString.getStartPoint().getX();
y_start = lineString.getStartPoint().getY();
x_end = lineString.getEndPoint().getX();
y_end = lineString.getEndPoint().getX();
