Re: [Talk-us] NYC Name Vandalism

Hi, Perhaps I didn't express it clearly, but my interest was in the idea that certain. rather limited changelists could be flagged for moderation before they are put into main dataset.  There will always be things that seem like they should be blocked, but are actually appropriate.   In the

Re: [Talk-us] NYC Name Vandalism

Hi - I haven't commented on this forum for several years, but this event did catch my attention. There are some uses of OSM map data which would not allow for frequent updates - offline uses - and therefore, a way of catching such vandalism immediately - less than a day, even - would be very

Thanks for the responses to these questions ... I'll have to carefully consider each response.  I' By pre-existing schema - I mean the something that looks like the shapefile formats of one of the major commercial map data providers.  We have tools that can consume those formats - and my hope

[Talk-us] converting .osm to a particular shapefile schema

Hi - I have a question about exporting OSM data.  Pardon me if this is the wrong group; please direct me to the correct one if it is. I'd like to see if I can take .osm format data, and rearrange it - to the extent possible - to shapefiles using a pre-existing schema.  What is the easiest

Re: [Talk-us] Use of highway=tertiary

In an urban area, I think of tertiary as being the road you use to go between and through neighborhoods. I also aim for a particular aesthetic: Between every pair of primary roads, there usually will be one or two secondary roads. Between every pair of secondary roads, there usually will be

[Talk-us] city polygons too large for potlatch to handle?

Hi - This might not be the right group to direct this technical question - but I'll put it out there anyhow. I noticed a little while ago that city polygons where added to the OSM database (at least in the SF Bay Area) - and that's a good thing.  There is a city boundary that runs along a

Re: [Talk-us] Public Domain Non-GPS Data Question

This is still treacherous ground. Say you compared Yahoo and Microsoft - and they had the same name. It doesn't matter - the real owner of the copyright to that data is Navteq; it's still a single source, and you could still be caught by copy traps. It's always better to rely on sources without

Re: [Talk-us] Fwd: [Talk-us-bayarea] Backcountry weekend

Oh, I thought they had to discontinue this for lack of state funds ... I've gone on this event twice - not for the purpose of mapping, but it's a good way to see some wilderness surprisingly close to the Bay Area. A fair bit of this area got burned by the massive 50,000 acre fire 1 1/2 years

Re: [Talk-us] US Highway Classification (Was: directions of ways in MassGIS data)

There was a discussion on this list ("Road classification") a short while ago about the "Highway" tag that should be revisited. Someone posted a classification system back in December that made a lot of sense, and is more in sync with what I know commercial data providers. Basically, it would be

Re: [Talk-us] County Line Corrections

I know of some weird cases of borders and rivers, particularly along the Mississippi, where it has changed course. There's a case near Wilson, Arkansas where the river has changed course, and a few square miles of land on the west side of the river belongs to Tennessee. However, for obvious

Re: [Talk-us] US Route Tagging With Relations

A couple thoughts: 1)  Commercial data providers have use a route type parameter that designates something as an Interstate, Federal Highway, State Highway, County Road, or Farm-to-Market road.  This code does not distinguish between states; all state highways have the same route type. 

Re: [Talk-us] US Route Tagging With Relations

I like the idea. In GDF - a (supposedly) standard exchange format for geographic data, they have the concept of composite attributes. I think of a relation used in this way is really better described as a composite attribute that can be applied to many elements. It's best to specify highway

Re: [Talk-us] Tagging and Rendering Cycle Ways

My inclination would be to want an extra class of routes or two supported with different network type (perhaps unlcn for unnumbered local network?) for the lowliest of bike routes. I'm not what I'd want done for expressways. Perhaps there could be a way to tag a road as treacherous for

Re: [Talk-us] Tiger Data 2007

There's another consideration ... what if a TIGER import is done somewhat carefully, but not quite carefully enough? So 90% of the areas are made better, and 10% are made worse ? If those 10% are located where someone has poured their heart into making a carefully constructed map - you

Re: [Talk-us] Tiger 2007 Data

Then, decide how if/when it is appropriate to write over the old TIGER stuff with new. Or, to merge it somehow. Be very, very careful here. Conflation is a difficult thing. I used to work at Tele Atlas, and there was a major project to conflate Tele Atlas North American data and GDT data

Re: [Talk-us] US GPS Set for Mapping Parties

As someone said, it's possible that Garmin would consider OSM a potential competitor, however that's not certain and it does us no harm to try. OSM would be a competitor to Navteq or Tele Atlas, I'd think - not Garmin. Which makes me curious - Garmin may get a small profit for repackaging

I can say what I do ... First I'd verify that there's no extra information attached to nodes that I'd consider deleting.  :) Then I'd make a judgement:  as the nodes are positioned now, do they make the road look a little crooked in a way it really isn't?  If it does, I start thinning.  The
