Hi, Because it is not obvious to everyone what the extent of the NTS sheets is, I've created a little service which converts them to lat/lon coordinates. It is also possible to show them directly as a box in OpenStreetMap. I'm not sure if a similar service exists (probably NRCan has one), but this might also be useful for the Geobase import.
The main entry page is at http://www.steggink.org/geo/ At the bottom you can enter the NTS sheet number. It can be done in the formats 'NNN', 'NNNL' or 'NNNLNN' where N is a number and L is a letter. When you press the Submit button, you'll go to a page which shows the center coordinates. (No extent yet.) For example, entering '021L14' (the sheet containing Quebec City) leads you to http://www.steggink.org/geo/nts_area/021L14. From there you can go to various services accepting coordinates, like OSM. When you press the OSM button in the main page, you'll directly see the result as a box in OSM. The "calculated" URL http://www.steggink.org/geo/nts_area/021L14/osmbox gets you redirected (HTTP 301) to the OSM site: http://www.openstreetmap.org/?minlon=-71.5&minlat=46.75&maxlon=-71&maxlat=47&box=yes This means that you can also use the URL at my site as a template, replace the bbox, and you'll directly go to the OSM page. The next idea I had would be to using these URLs at the Geobase import status page, so everybody sees directly what area exactly was imported. If you notice any errors (especially in the polar regions, due to the inconsitent box sizes), please report them to me. And yeah, this is not entirely RESTful, because errors are also returned as HTTP 200 - OK :) Regards, Frank _______________________________________________ Talk-ca mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-ca
