Hi, Regarding government contacts: I believe Nicolas has contacts within the government himself, so he might be in the best position to make some inquiries. It would be wonderful if we could do something really useful with it (i.e. importing in OSM).
I've looked at the 1:1M data, and it is in E00 format. With some tools (Import71 from ESRI and ogr2ogr) I was able to convert it to SHP, and then I used shp-to-osm.jar to convert it to OSM files. So far I haven't used any rules files, so I got the bare geometry. Maybe I haven't done right in this quick test, but the OSM files don't contain areas, but lines. Actually this is perfect for administrative boundaries. Any administrative areas should be built up by relationships anyways. Regarding the accuracy, it was much better than I would expect because of the scale. If there would be no alternative, this would certainly be acceptable IMHO. One thing though: I couldn't find any names of the areas. The generated DBF files only contain numeric identifiers. During the conversion to SHP (through ArcInfo coverages) I got an error from ogr2ogr that it wasn't able to convert integer lists to SHP. I don't know the data, so I also don't know what data has been dropped. Maybe the identifiers of the area to the left and right sides of each way... The Geoboutique site also has lots of other interesting data, like orthophotos. Too bad they're expensive. $65 per file, and there are thousands of them. However, we wouldn't "need" that data per se, but if it would only be available to OSM for tracing purposes (like Yahoo), that would already be very much appreciated :) Frank Sam Vekemans wrote: > So Quebec (province) has not opened up their dataset yet? > Good to know. > Maybe after the NRCan data all gets imported, they might change their mind :) > > Does anyone have contact with the GIS department directly? > > Sam > > On 1/15/10, Pierre-Luc Beaudoin <[email protected]> wrote: > >> On Fri, 2010-01-15 at 22:18 -0500, Pierre-Luc Beaudoin wrote: >> >>> We should get in touch with them so we can exchange datasets such as >>> Municipalités régionales de comté, City boundaries, counties and >>> administrative regions (at least). >>> >> They do have the data (1/20 000) in vector format available for sale for >> 100$ + conversion rates of 7$ on http://geoboutique.mrnf.gouv.qc.ca . >> Past that, it's only a question of licences. >> >> Pierre-Luc >> >> > > > _______________________________________________ Talk-ca mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-ca
