[gdal-dev] GNM Usage

[ChiefDan]

Thanks for the response. The source data is in EPSG 900913, the network data
according to ogrinfo:
PROJCS["WGS_84_Pseudo_Mercator",
    GEOGCS["GCS_WGS_1984",
        DATUM["WGS_1984",
            SPHEROID["WGS_84",6378137,298.257223563]],
        PRIMEM["Greenwich",0],
        UNIT["Degree",0.017453292519943295]],
    PROJECTION["Mercator_1SP"],
    PARAMETER["central_meridian",0],
    PARAMETER["false_easting",0],
    PARAMETER["false_northing",0],
    UNIT["Meter",1],
    PARAMETER["latitude_of_origin",0.0]]

Looking at the individual point values, they seem to be EPSG 4326:
OGRFeature(gnm_Frog_Branches_point):1
  name (String) = 78B-S-0
  gfid (Integer) = 68
  POINT (12.305749698885625 45.450093091932679)

For a line with multiple point objects on it, will the GNM processing break
the line up into multiple segments creating the line segments between the
points?
Also, if there are overlapping lines that form a Y intersection, can the GNM
processing recognize that as a potential path?
