And, if people go out to map, it helps to have someone stick around at the coffeehouse (for any stragglers to keep the space). In the SF Bay Area, we had the unfortunate experience one weekend of not noticing that the Cafe had a policy of providing wi-fi only during the low-traffic week days, but turned it off for Saturdays and Sundays, so make sure to check that it will be available when you actually need it. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Re: [Talk-us] A Friendly Guide to 'Bots and Imports

I had initially planned to import the whole darn thing in one swoop, but various technical and life challenges came up before I could get it going. While I was working on those issues, people started importing it themselves (sometimes marking so on the wiki, sometimes not). Now that there are some areas imported, the import of the whole dataset becomes infinitely harder because we have to match existing data with new OSM-ified data. And I'll add my own mea-culpa. I created some wiki pages/features to help partition and coordinate NHD import efforts, and then also found that I didn't have the time to follow up. I would agree that the partial imports will have increased the difficulty of a large-scale bulk import, but we already had hydrographic features from TIGER, did we not. And hand-drawn features from aerial traces and actual boots-on-the-ground mapping. Conflation in general is a tough problem, I gather. There are tools, algorithms and heuristics in the GIS world but the OSM data model makes translation between the two models somewhat difficult. For example, something that looks very interesting which I plan to examine is the Java Conflation Suite [1], which looks like it could be used over relatively small areas (probably about the size of the API limit... 0.25 degrees square?). But as a component of the JUMP[2] platform, it operates only on Shapefiles and GML out of the box. (If we could get some Java expertise I think it would be very worthwhile working with the JUMP team to create an OSM driver.) At any rate, while I think we could mitigate a number of problems given some development effort, I also agree that we might want to spend more time thinking about why we want to make the imports--and perhaps publically debate, if only in talking to yourself on the project wiki page, the pros and cons of a particular import.

[Talk-us] How would you tag this? (nested land-use/ownership)
Driving around yesterday, I found the following unmapped feature: A private dog training facility (Schutzhund club), with a building and training yard... ...in the middle of a mostly vacant field in an industrial area, which ...is diked, former marshland, which... ...is owned by a salt mining company, and.. ...had been designated/zoned at some point as landfill and tagged as such in a bulk import (which I've since removed). Of course I'd like it to be rendered in Mapnik and/or Osmarender so that Jane Q. Public can find it but, what are the correct tags here? * It should have a boundary of some kind but the true physical boundaries are rather vague; two sides have an old fence but the others have levies with gaps to open fields. * It's not really a dog park but rather a private entity with dog training facilities. * None of the landuse: tags really seem to fit, especially for a single entity like this.

I've got a bit of time to start working on the NHD import again, and after importing both OSM and NHD data into my GIS app, I'm not quite sure what to do with it; that is, I don't really have a procedure for resolving conflicts visually/manually, let alone automating the process.

What is the intent of the tiger:separated tag? Was it to indicate that a single way actually represents a set of two or more parallel ways? What should we do when we modify a single TIGER way to represent the true divided nature of a street/road? For example, when I copy the entire way and paste a copy offset by a few meters to form the other direction of the road? Should tiger:separated be considered immutable and left alone? Or deleted?

But a few short sections are inaccessible and follow the highway. CLEARLY there is value in having the route of the trail in the database. Should the trail have its own way which shares the bulk of its nodes and path with the railroad way? Or should the railroad and highway portions of the trail be marked with ... something? And how to carry the name of the trail the entire length even though it travels on the railroad, highway, and a purpose-built section?

How do we work with the people responsible for the Mapnik configuration on the main map interface, to get these HND features rendered nicely?

There are a lot of natural=water features in my area which do a good job of approximating the nature of the edges of the bay, which will disappear from the current Mapnik rendering when we correct their tagging. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Perhaps we could just start an import with tags that make sense for these things (e.g. natural=marsh).

What are you using the import the data? Also, I've got a very robust SHP - OSM (Now with Multipolygons!) converter written in Java coming soon. Currently it converts the geometries in the shapefile to OSM primitives and relations and applies the tags from the shapefile attributes. The OSM-specific tagging will have to be added with JOSM. I'm trying to think about a nice way to let the user apply OSM tags based on SHP attributes and the context that you're in (multipolygon inner, outer, linestring, etc.) Anyway, to answer your question, I think we first need to: 1) Standardize on FCode - Tags 2) Keep track of which HUC codes are imported and by whom. (I can start working on this as a wiki page) I'm still experimenting. I've been looking at a commercial tool (ExpertGPS) to convert shp to gpx, and then GPSBabel to convert to OSM for use in JOSM. I'm also using commercial GIS software (Manifold) to work with the shapefiles at the beginning of the process. I get the advantage of being able to graphically select/edit features, but I don't yet have any way to translate shapefile attributes to osm tags. Should we start a new wiki page to document the NHD FCode -- OSM Tag mapping? I've just begun looking at the NHD technical instructions.
