Using osmServerClient ?: msg#00045gis.openstreetmap.devel
I've been trying to extract data from OSM by using osmServerClient, but with little luck. What I do is that is I create an instance of osmServerClient() and calls getNodes (..) on it. No matter what LatLonPoints I feed it, I get 0 nodes back. The applet works as it should (even when I start it locally from dist/applet.sh), so it must be a really stupid mistake I do somewhere :) I have tried both with and without calling login() first. Login seems to work as it should, since I get an error when I give an invalid username/password. Since getNodes() doesn't require a login, the test program below is without it. The short example program below tries to extract the points from an area around my home town: OpenStreetTest.java > import org.openstreetmap.client.*; > import com.bbn.openmap.LatLonPoint; > import java.util.*; > > public class OpenStreetTest > { > public static void main (String[] args) throws Exception { > osmServerClient client = new osmServerClient(); > // retrieve data set for Trondheim, Norway > // 63.42216N 010.39334E > LatLonPoint a = new LatLonPoint(64.0, 10.0); > LatLonPoint b = new LatLonPoint(63.0, 11.0); > > Hashtable h = client.getNodes (a, b); > Vector v = client.getLines (h); > System.out.println("Got " + h.size() + " nodes and " + > v.size() + " lines"); > } > } Output from the program is: > % java OpenStreetTest > grabbing nodes... > result = [] > Spent 1519 in request > Calling getNodes took 1703.0ms > reading Lines... > result = [] > Spent 217 in request > Calling getLines took 220.0ms > done getting lines! > Got 0 nodes, and 0 lines Any clues on what I do wrong? --Magne
