Hello all, I’m about knee deep into developing a program using
the GT2 2.2 library. I’ve parsed my way through a couple of the examples
and gotten enough of the code working to the point that I’m getting
dangerous. Anyhow, I’m trying to take a set of city roads from a
shapefile and use the Graph Builder module to turn them into a network(nodes,
arcs). I’m getting a runtime error from the following code in the
add() statement. … BasicLineGraphGenerator lgg = new BasicLineGraphGenerator(); FeatureCollection
collection = null; try { collection
= fsShape. }
catch (IOException e)
{ // TODO Auto-generated catch block e.printStackTrace(); } FeatureIterator
iterator = collection.features(); while (iterator.hasNext()){ Feature
f = iterator.next(); lgg.add(f); } Where fsShape is
a working instance of FeatureResults with about a hundred roads in it. I’m not
sure if one of the elements is a problem adding to the graph or if the whole
structure is bogus, which leads to second question: I downloaded the
2.2RC3src in an attempt to troubleshoot, unzipped it, mvn install’d it, got
a good build, and it doesn’t appear to contain the source code…? Just
the full set of .jar files with no source attached? I’m a
maven novice, so maybe I’m gooning something up there. Any help or
anyone with experience in the graph module who could lend some tips/source code
would be appreciated. Thanks, Jeff |
