National Public Transport Access Nodes (NaPTAN)

I am quite new to geolocalisation. How can I convert easting and northing to latitude and longitude?

Thanks

The data could be better documented. Is it possible to identify stations that are grouped by line. Ie I am not interested in returning the next nearest station on the same line, but would be good to return the next nearest station on a different line.

Is this information available via a WMS or WFS web service ?

Can anybody tell me if the following is possible?

I would like to take the 'Stop.csv' data and then map this in a mapping API (perhaps the Google Maps API, or the OS Opensource API).

I assume that the Stops data is potentially susceptible to change (with new bus stops being added or deleted) and as such I would like to programmatically grab the data (run from a server side scheduled task) and then write this to my database (maybe a PostgreSQL db – not decided this part yet though).  I understand that the in reality the Stops.csv data may not be updated that regularly - however at at the moment I am just looking at a proof of concept (i.e. grabing csv data from a URL and then mapping accordingly)

If there is another way of doing this please do let me know!

Any help appreciated!

You might want to take a look at the Northing field for West Brompton Station.

It plots a few miles South of Brighton !  I think it is missing a '1' at the start of the grid reference (I compared against OS Meridian 2).

Is it possible to link bus (or rail) stops based on the busses that service them. This would let me build up a proper transport network. Apologies if this is explained elsewhere, I haven't found anything.

Thanks,

Nick

The dataset and metadata appear to have been updated 2011-04-01, but the page http://data.gov.uk/dataset/naptan still says 2011-01-01.  I'd been waiting for the new dataset only realise now that it was actually updated a few days ago.

This doesn't seem to be due to caching by my browser/webcache or even in Varnish on the data.gov.uk side.  Is this a problem with the data.gov.uk website code?  Could it also be affecting other datasets?

I am wondering why the airport reference file does not have Eastings and Northings when the rail, coach, ferry and bus stops do have them?

Am I understanding correctly that the date of the current csv download is January 2011 and that it is updated quarterly here on this website?

Thank you

Two questions:

1. Is the MetroRef field populated?  I can't seem to get hold of that field for any of the StopPoints I access.  Related to this, some Underground stations have CRS codes associated with them (e.g. High Street Kensington has CRS Code ZHS).  Is there a timescale for incorporating this data, or am I maybe missing a trick, and failing to find it when it's already there?

2. In order to integrate this data with London bus routes, is there any link between the LBSL Stop code and the Atco Code?  I've been searching for something that will help me do this, but I've drawn a blank so far.

Many thanks,

Hi,

Something that many people have been asking for, I've begun writing my own SOAP-like API to retrieve some basic stop data. I plan to extend this to return more information, such as the locality from NPTG, but for now there is a demo at:

http://opendb.steven.hosting.pyro.eu.org/apps/naptan/

To do this, I wrote a nifty importer to decompress the ZIP'd XML on-the-fly and insert data into PostgreSQL, which is free and open-source from:

http://opendb.steven.hosting.pyro.eu.org/svn/naptan2pgsql/trunk/

A SQL dump of my database (currently only containing some basic stop data, though) can be obtained at:

http://opendb.steven.hosting.pyro.eu.org/datasets/naptan/export/

Thanks for the clarification on licensing; until then I would have been unable to redistribute the data in the ways I'm doing here.

The MetroReferences.csv file is empty. Does anyone know of another source for this data in csv format or is is it currently not available? Thanks

I think all stops (including bus, train and more) have ATCO codes, which are sometimes mentioned on the timetable printout at the stop. These are unique, alphanumeric identifiers.

Many stops also have a separate NaPTAN ID, which is the same as the Traveline txt-code often displayed at a stop as well. If a NaPTAN code exists for a stop, it will be unique. I think these are letters only.

What identifiers would you use for a bus stop?

I'm still confused with the licensing here. Can this be used for commercial or semi commercial use?

Isn't it Access Node (in the singular)?

I've noticed another problem here; the downloadable XML metadata's 'license' tag refers only to the DfT Terms of Use, which prohibits commercial uses; this page however says that data.gov.uk rights apply (which encourage commercial use). So, which is it? Please clarify this.

The linked terms of use seem to exclude commercial use: "Use of Data - Use of the NaPTAN data is subject to license by the Department of Transport. Public Sector and Commercial Licences are available. Fees may be charged for Commercial Licenses. "

I also notice that these terms of use were last update in August 2009: "Page last updated: 06.08.2009"

I assume that these terms will now be adjusted to fit with data.gov.uk aspiration that commerical use is allowed taken from the data.gov.uk FAQ: "Q. What are the commercial use rights if people have commercial ideas? A. Crown Copyright enables you to use all our data for commercial purposes. We are delighted that you see a commercial opportunity in using our data.
