[talk-ph] to share or not to share nodes?
Hi, I'm posting this inquiry to gather best practices when editing nodes and ways. Basically, OSM data are composed of two data primitives: nodes (points, vertices) and ways (lines and polygons). Relations are special type of ways and nodes. The data model allows for sharing nodes/ways with different tags. For example, a node can be part of a highway, traffic_signals can be added to node which is part of a highway way. However, in many cases it is good editing practice to minimize node sharing. Partly for ease of editing and partly to avoid routing errors (especially for highway ways). Here's a list of editing practices I will use from hereon in order to avoid node sharing problems mentioned above. Please add or delete anything in the list. 1. Highways should not share nodes with other non-highway related ways (such as administrative boundaries, landuse, building outlines) 2. Nodes for adjacent landuse types can share nodes. 3. Administrative boundaries should be in relations not as shared nodes/ways. 4. Natural and landuse ways can share nodes. For example, natural=water (for lakes) can share nodes with landuse=farm. 5. Admin boundaries should not share nodes with landuse. Landuse change more often than admin boundaries. 6. add more here ... -- cheers, maning -- Freedom is still the most radical idea of all -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ -- ___ talk-ph mailing list talk-ph@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ph
[talk-ph] Fwd: import_arivac_bohol
This thread is related to the arivac bohol tagging. I'm forwarding this to the list so that bohol mappers can catch-up on the discussion. Thanks to rally for pointing this out. -- Forwarded message -- From: maning sambale emmanuel.samb...@gmail.com Date: Mon, Apr 26, 2010 at 9:28 AM Subject: Re: import_arivac_bohol Hi, (I think this message should be on the talk-ph list, so that Bohol mappers should be in the loop. I'll answer some anyway.) The source data didn't have a separate tag for various POIs. For example, Eatery/Restaurant/Bakery/Coffee was lump into a single POI type, hence, I used a temporary tag amenity=fast_food. I suppose the ARIVAC project didn't saw the need to separate them.

For example, natural=water (for lakes) can share nodes with landuse=farm. I'm never quite sure how I should be doing beaches [being a bit of an accidental island specialist .. :-)] It seems fairly logical to join the seaward edge of the beach to the coastline. Is that OK? Does it play well with the 'shapefiles' whatever they might be ... On the other hand I have some misgivings about it, because its a hassle to un-glue the beach edge and the coastline when you need to edit/move the beach. Hmmm.

Re: [talk-ph] import_arivac_bohol
Hi, Item 19 (internet cafe) tags are based on this page : http://wiki.openstreetmap.org/wiki/Key:internet_access A computer icon would indeed be better than a coffee cup, but in France for instance, an internet cafe often really looks like a cafe with a bar/counter too order drinks.

[talk-ph] OSM Editing Tip in 5 Minutes screencast series
Hi, I'm making some videos on editing data in OSM. This is intended for newbies. My plan is to make short screencast focusing on one feature/editing tip. So far I made two videos using Potlatch as an editor: - Splitting ways in Potlatch - Edit data using your uploaded GPS tracks See videos here: http://vimeo.com/user1958568/videos Suggestions are welcome. If you have a tip request, let me know and I'll try to make one for you. I hope this helps pinoy newbies break into the initial barriers. :) Other videos you may find useful are here: http://showmedo.com/videos/series?name=mS2P1ZqS6 PS. The first 2 vids are a bit fast (I'm still playing around with xvidcap's settings). Just replay the vid in case you missed something when you blinked your eye. :) -- cheers, maning -- Freedom is still the most radical idea of all -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ -- ___ talk-ph mailing list talk-ph@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ph
