Hi all,
I'm preparing a road import for Finland based on NLS of Finland (nls.fi) dataset. Since OSM is quite complete in many areas already and even significantly exceeds the quality of the NLS.fi dataset the import is meant to be selective. I.e., I've calculated isolated subnets in the road dataset that do not overlap significantly with existing OSM data, only those parts are to be imported in the phase 1. All subnets are supposed to be manually reviewed and there's also some additional road classification that cannot be done solely based on NLS classification system. The tasks will be divided by subnet granularity to mappers in Finnish OSM community. In general, the OSM community in Finland is quite excited about the dataset. I received some positive and constructive feedback from there which has been useful to improve the toolset to calculate the subnets in a more useful manner. The import is coordinated using OSMTM based tool which deals with collision avoidance, bookkeeping and displays the result of some auto-validation happening during updating of the subnets. The auto-validation and updating of subnets based on data appearing in OSM yet to be implemented but neither seems hardly complicated task compared with what I've tackled so far (I'll mention it here once I get that part fully implemented, however, it should have implications only on keeping track of progress, the data such remain exactly the same even with that update/bookkeeping process in place). Permit to add attribution to /copyright page is on the hands of LWG and hopefully that is resolved eventually (NLS.fi dataset is expected to become large-scale contribution in Finland with much more than just road data in the end, so addition to /copyright page is as per import guidelines and it's what NLS.fi said to be satisfied with regards attribution). Please check the more detailed plan: http://wiki.openstreetmap.org/wiki/Fi:Maastotietokanta/Road_Import_Stage1_Plan Preview about the coordination tool is running at: http://ijjarvin.kapsi.fi/osmtm The coordination tool shows the convex hulls of the subnets and provides links to .osm files (allows talks directly to JOSM remotecontrol), which you can use if you want to review the resulting subnets and the data in them (one caveat though, the exclusion of non-cable ferries is too new addition to yet affect the subnets but this is to be dealt with in the near future). The OSM data against which the NLS.fi dataset was compared is few days old now, so don't be surprised if you find one or two subnets that are already added through normal mapping while we speak (I managed to find two of such just today which turned out to be non-bugs because of very recent manual drawing by somebody). Once I get hourly updates working, these problems will vanish (or at least the latency is cut to hardly noticable level). I've written step by step guide for the process for a mapper participating in this import which also tries to highlight the importance of eyes visiting all around Finland viewing not only the data to be imported but surroundings too and I hope that also pays of as fixes also to the existing data in the regions surrounding the subnets itself.
