[GraphHopper] Ordnance Survey Loader

[me]

Geotools has an embedded database (hsqldb I think) with EPSG projection information. The error may be that this database hasn't been included in the build.

Hi Stuart,

this is nice - thanks!

I took a closer look at it. There seems to be an old graphhopper.sh script? Also I had a problem with the import when using the sample data you mentioned**

What I did I described in the 'current instructions' of the issue #227 and let us move the discussion to it: https://github.com/graphhopper/graphhopper/issues/277

Let me know when you think that this is stable enough, then we can work together on improving the abstraction and refactoring mentioned in the notes, if you like.

Kind Regards,
Peter

Hi All

The dependency on internal code has been removed from the OS ITN data loader by using geotools.
This means you should be able to try it out now.  Some of the tests currently fail but the basics work.  To build you will want to skip the acceptancetesting module, since that is an internal test which will probably be moved out of this repository as it is data dependant. For now skip tests whilst I figure out what has broken the unit tests, hopefully tomorrow.

To run graphhopper loading itn files supply the following configuration options


osmreader.osm=<path to data file as normal but this should be either a directory or itn xml file rather than osm>

reader.implementation=com.graphhopper.reader.osgb.OsItnReader


the reader.implementation setting changes which DataReader implementation GraphHopper uses with com.graphhopper.reader.osgb.OsItnReader and com.graphhopper.reader.OSMReader now implementing an interface DataReader.  if reader.implementation is not set com.graphhopper.reader.OSMReader is used by default.

osmreader.osm setting should probably change to datareader.src with this change but for now I have left that alone for compatibility reasons.

Once the data is imported it can be used in a standard GraphHopper server without having to switch reader implementation which means ingested data should work in a GraphHopper instance from the main repo without consuming the engaric/graphhopper branch though I believe at the moment I need to resync with graphhopper/graphhopper repo as I suspect the graph version has been changing rapidly recently.

Sincerely
Stuart Adam
