| Beyond First Edits! | hey, Awesome to see such enthusiasm to OSM ! Just to briefly answer some of your questions: I also osmtracker on my android, and like other gps devices, you’re GPS signal is not perfect, you’ll notice there’s a little ‘accuracy 5m’ on the top of the main screen of osmtracker, which means that there’s up to an error up to 5m of your current location. Even if your signal isn’t perfect (I usually get no better than 2-3m; usually it’s 5-10m), for example 10m, it’s still accepted to upload that trace. “survey:2012-10-25 with Bing correction” in the source tag is quite acceptable. If you don’t remember the exactly survey date, for example, I’ve seen other users just put survey or what I just personally do, is put a brief note of what I edited and its source, like “[personal visit, bing]” in the comment before I Upload my changes to the server (called a changeset) osm.wiki/Changeset I haven’t used potlatch much so I don’t know if making a changeset comment is any different. |

| Just mapped The Legacy Village |
hey, thanks for mapping it, very nice job. extremely detailed. cool that you had fun. that’s not too far from me - probably about 30km. I only have visited once or twice in the past couple years (it’s where many very well-to-do in the cleveland area go to shop) and that’s there so much other mapping to do in Cleveland and other osm-related projects that I (and the handful of other users) haven’t had time to map it yet. There’s also also another shopping complex, beachwood place just diagonal from there too. :P |

| WOF#7. Import guidelines |
This is a great start! Although I’ve only done one import before, I’d probably also move the license to the second step, after all, doing all of the work and then finding out that you cannot add the data would be disappointing. |

| The Growing OSM Community in Cleveland, Ohio (USA) | Minh, Unsolicited ! That some of the students have continued to edit is great ! I also saw one of them edit in Cleveland as well. |

| secondary_link appears underneath residential ways ?! | Thanks for the responses... I understand that it shouldn't be secondary_link (and probably secondary) and I'll change it, but I wonder why secondary_link appears like that in the first place. |

| OSM.org UI updates | Thanks too for the devs for implementing them. |
|
| OSM.org UI updates | I noticed this as well and was about to make a diary entry on it ! I'm a little surprised the dev's didn't make an entry in the news section on the wiki. I don't know which specific changes were implemented and when, but I like the changes. =)

| How I Map: TIGER Cleanup | I meant to send this as a comment instead of a private message...
With road classification, I use the same practices as you for TIGER (here in Cleveland, OH). I also find tertiary relatively ambiguous, with no absolute rules of when it should be applied. I usually decide whether it's tertiary [or unclassified or residential] by a combination of factors: if the speed limit is 35, as opposed to 25 in most residential, the amount of businesses/other uses other than residential on the way, the amount of traffic it receives [relative to roads in the area], the # of lanes, and last, certainly, not least, just a general feel. |

| Efficiently merging government park boundaries in JOSM | Thanks for detailing this ! I'd also like to import the parks in my area (they're also available as a shapefile), although it's admittedly not high on my priority list. If I ever get around to it (or the more likely scenario, I can point another user to this if they wonder how), I'll keep this in mind and bookmarked ! |

| How to create an OSM extract of your city. | Thanks for the info, I'm anxiously waiting to try that query once more as each time I have tried [3 or 4 today], the server is overcrowded :( After just 2 or 3 seconds of submitting the input I have received the message:

| How to create an OSM extract of your city. | Chriscf,
Through my searching, I found a couple suggestions in http://help.openstreetmap.org/questions/8273/how-do-i-extract-the-polygon-of-an-administrative-boundary and I'll be testing those out in the next day or so to see if they will work. |

| GPS visualizer - minor updates | Cool project ! I tried to run it and unfortunately received an error as follows: BACKGROUND_COLOR = #000000

| Rendering the Lake Erie Coastline using Osmarender (Update 2) | The second osmosis filter that I run to remove ways information in the bounding box that I do not need: osmosis --read-xml v5.02-extracted.osm --way-key-value keyValueList="highway.motorway_link,highway.motorway,highway.primary_link,highway.primary,highway.secondary,highway.secondary_link,highway.tertiary,highway.residential,highway.service,highway.unclassified,railway.rail,railway.light_rail,railway.tram,railway.subway,waterway.stream,waterway.river,waterway.riverbank,natural.water,natural.coastline,boundary.administrative" --used-node --write-xml v5.02-filtered.osm |

| Rendering the lakefront using Osmarender | Here's an update of how I progressed since then. The problem: When downloading data from OSM, the geographic area is (not always, but for the sake of this post, most of time) shaped in a rectangle defined by the bounding a north, east, south, and west coordinates (known as a bounding box). When it comes to coastlines in OSM, the entire area is not downloaded, just the data within the bounding box. This can be a problem if your data partially contains a coastline and the data does not specify which side is land and which is water ! Thus, here's what you should do if you have a large coastline to render in osmarender.
close-areas.pl will download the additional coastline that was not in the bounding box and specify the area(s) near the coastline which contain water. After running close-areas.pl, my output .osm file, once rendered, still did not have water in it.
but the parameters of the
I had mistakenly entered the bounding box coordinates in the same order of the API, not the specific order used in close-areas.pl The correct close-areas.pl was: EDIT: I haven't fixed it yet I was able to render the coastline using an area of bounding box that consisted of the mall portion of downtown Cleveland (the above coordinates), for the sake of simplicity during this debugging process. However, when I attempt to run the above using the bounding box of the entire city of Cleveland (the same used for the Cleveland Neighborhood Map), the water is displayed everywhere on the rendered image, instead of just Lake Erie. |
