[Talk-ca] Correcting Geobase_import_2009

Looking at my local map in Orleans Ontario noticed that Merkley Drive does not connect up to Charlemagne. Merkley Drive is tagged Geobase_import_2009 and all sorts of interesting things. Charlemagne is just tagged potlach and residential road. Is there an easy way to extend Merkley Drive so it d

Hi, just use potlatch & connect the roads. No harm done :-) The OSM changeset history keeps track of attribution and such. If you want a copy of where the geobase version of that road is, i can provide that. The system that imported the roads didnt want to interfeer with what work previous peopl

Yes I'm new and my background is red tape. I understand there is a lot going on and I appreciate the work that has been done. My background is in databases etc. If you ask clients what they want they always rate reliability above anything else. To me the data from geobase is good high quality da

OK accepting what you say is there a way to identify where an old OSM road was so that some one can go back and clean up the new geobase added data?  Connect the roads and insert road sections that have been deleted?  I think Toronto organised something that recognised the quality of the data b

Looks like I can do an extend and combine in JOSM. Thanks John > On the clean up side is there an easy way to copy the tags on one section of > road onto another?  For example when I extend a geobase road up to the old > OSM road I'd like to have the same tags as the other sections of the road.

Hi Sam, I've just downloaded some CanVec data, and had a look at sheets 031I07 and -08. I wonder what you mean by uploading all "sub-residential files". I understand that the data is separated over multiple files, because of certain limitations. In the residential OSM files I also see no polyg

In JOSM, another way to quickly add on to a way like that is to use the select tool to select the way you will be adding on to, holding the shift (or control) key, selecting the last node in the way, then use the draw (add) tool to continue drawing the way. By default, in JOSM, if you have a node s

Hi, I think to know what is going on. I've tried to convert the residential areas of 031I08 myself, and I got an OSM file with an outer polygon. However, the outer polygon has no tags. Also, it looks that Sam's batch files run shp-to-osm with the -t parameter, which suppresses the output of fe

I found both James's and Sam's comments very useful.  It gives me a much clearer idea of what you are trying to do and the limitations involved.  It would appear that we have the ability to identify roads omitted from the geobase import which means at some point in time given enough resources a

Hi John, I personally think it would be better to do the cleanup immediately after the import, or possible during the import. Of course it is very tedious to do so, and it will slow down the import, but the person who is doing the import, knows best which roads were omitted. The goal is not to

The difficulty with this approach is people keep adding data. Which is fine if its high quality but where people are doing tracing on lower quality data you end up with a mess. I think you have to accept that with the OSM approach the data will be of variable quality. Even users with WAAS GPS de

Hi Sam, It's either that you'll end up with 0 byte files, or with files without any outer polygons. The former is just an inconvenience, while the latter is a problem. ;) Anyways, before you generate new data, I think someone should have a look at shp-to-osm, to check if my assumption that the
