OpenStreetMap

You guys are great

Everyone was right. This is way to addicting! I'm not sure if I was just looking for a hobby or if I feel I am part of something bigger then the things I normally get to do. Whatever it is I can really get use to this...if it does not drive me crazy first. =)

I'm amazed to see how much needs to be done in my area (Northern Colorado) yet alone everywhere else. I just want to fix all of it now! But wait, there are still things to learn and I keep finding new ways to tag things and just now understanding the remarkable detailed nature of what the editor can accomplish. Some of the tiger information looks very cluttering but I am not sure quite yet what can be trimmed and what is really usefully to leave. So needless to say I have been reluctant to make changes to things other then what I am certain of at this point. Any help here would be appreciated as I am still wondering around the wiki pages.

Well, I've updated a ton of roads (priorities and incorrect tiger mappings) in the Fort Collins, Co. maps. Please feel free to look over these and tell me if the primary/secondary road labels I have been updating are up to par with standards. I'm slightly torn on whether to classify major city streets as secondary, or if they should be something less. I think all highways, regardless of state or US, should be primary. So hence my decision for labeling major city streets as secondary. Anyways...

This all has been driven from wanting maps in my Android "MapDroyd" program to render closer to how the web version of OSM, but maybe that is something I should take up with the developer. But if I am correct with my road labeling, that is not needed and mt mobile app will do.

What Android app is everyone else using? I need one that is offline as I will be hiking/camping this summer with no cell reception.

OSMtracker. It don't know how well it will work offline.

Welcome aboard, nsx2000. You're right--Colorado needs a lot of work. I mostly work Denver and surrounding areas, but, I am somewhat familiar with CSU and Fort Collins.
I realize the wiki comments can be confusing and contradictory. I tend to be a little more conservative on the primary/secondary designations than some other contributors. I don't think all state highways deserve a "primary" classification. E.g. CO-75 through Littleton is only 2 lanes and not that heavily-used, so I rated it secondary. CO-72 from Arvada to Nederland is a winding mountain road through a few sparsely-populated communities, so it is secondary as well.
As for Ft. Collins, I would probably rate lesser-traveled feeder streets such as Elizabeth as tertiary, whereas Shields is a major thoroughfare and should be secondary. Also, make sure if you change a designation in one segment, other segments for that way need to be updated as well. I noticed some tertiary bridges on otherwise secondary roads. Also, SR-14 is primary along Mulberry, but I think it extends up Jefferson to US-287, so that stretch should also be primary. Some contributors think a primary or secondary road should end only at another primary or secondary road. Feel free to split a way at an intersection and designate the two resulting ways differently--even if they have the same name.
As for Tiger data, I generally realign the ways and change the tiger_review tag to "yes" if I've been in the area and am certain of the location and name. I'll leave the id tag and leave (or change if it's wrong) the name tag; but other tags, such as left and right postal codes, are frequently inaccurate and depend on an easily-reversed direction. I feel these extraneous tags should be subordinate to an otherwise accurate map, so they can be removed.
These are just my opinions. I know others have their own ideas. Good luck, and thanks for your efforts.

A great Android app for OSM contribution is Maverick.

It can cache tiles (from Google Maps, Bing, OSM Mapnik, and OSM Osmarender) for offline use on your SD card. I've used it for hiking with pretty good success. It also has other neat little features, like displaying the number of satellites your phone is able to lock onto (see the bottom right of the main window).

Unfortunately, it's not open-source... it has two versions available, a Lite version (available in the market) and a paid version. The Lite version is limited to recording one track and five waypoints; the paid version has these limitations removed.
