Tucson is a City in Arizona at latitude 32°13′18″ North, longitude 110°55′35″ West.

Tucson is the second largest city in Arizona and the thirty second most populous city in the United States with 540,000 people ([1])

Overview

It would be great to recruit some new people to help with the Tucson map. At first glance it looks like a good map so far, but actually there is a lot to do. The majority of the roads are from US TIGER data and vary in quality from average to poor.

This page outlines some of the tasks. If you feel like helping then jump right in. It would be great to have Tucson become the best mapped population center in the State!

Note that you don't need a GPS unit to help with the map. A lot of work can be done by using the high resolution Yahoo satellite images.

Projects

Some projects are listed below. They are not in order of priority. Green = completed.

Project % Done Notes
Major washes 100%
Secondary washes 80% This is a guess. Hard to see from the satellite images, so might need groundwork.
Neigborhood washes 1% Hard to see on satellite images.
Cycle paths and routes 0% Perhaps we can get some data from the city or county?
Schools 10% See here for an example
Parks 20% See here for an example. Features to add include: grass, lakes, roads, parking areas, buildings, sports centers, etc.
Reid Park 80% This is a separate item because it is the city's major park. Still to do are: footpaths, ramadas with numbers, exact locations of disabled parking spaces.
TIGER fixing 15% See TIGER Fixup for some of the issues. The primary problem is roads in the wrong places. One method is to work on one section (a single square mile region) at a time. Roughly 10-15 square miles have already been completed.

To see the areas that need working on look at the red lines on this map.

Major buildings 10% Hospitals, "big box" stores, office buildings, grocery stores, hotels, convenience stores, malls, strip malls
Name streets 1% Some streets are missing names. The streets need to be added by visiting them. The roads marked in red on this map do not have names.
Tucson Mountain Park 50% Needs trails adding.
Saguaro National Park West 95% Trails from NPS added, but some are duplicates of TIGER trails. The TIGER trails are probably suspect but need to be double-checked before being removed. They are the ones shown with red dashes by Mapnik.
Administrative boundaries 15% Imported with the TIGER data, so they appear to be either crude or in the wrong places.
Incorrect Places 0% The TIGER import added places they either don't exist or used to. For example "Thunderhead Airport". These need to be checked and then removed if they really are not there.
Universities/colleges 55%
  • University of Arizona: 95% complete on buildings (some need name checks and outline checks from surveys). Tasks to complete: still need to add more footways, paved areas, green/grass areas and other features.
  • Pima Community College: 20% Eastern campus added
Downtown 95% Some buildings are missing names
Golf Courses 5% Need adding/more detail
Neighborhood Associations 10% Add the neighborhood associations as shown on this map. Note: probably can't copy from that map.

Some additional project ideas can be found on the Mappa Mercia page.

City of Tucson and Pima County Data

First a bit of background. Tucson, Pima County and cities in the area, such as Green Valley and Marana, cooperate on GIS services and data. The database is managed and maintained by Pima County with the other agencies feeding data into the system, getting data out of the system, and paying for a share of the costs.

Access to all the data is by a Pima County FTP system, and to get access a person must sign documents saying that the data won't be used for commercial usage, etc. Under the County definitions, OSM is commercial usage. Commercial usage is possible for a fee and prior approval. The County sells data to companies like Mapquest, etc.

Ann Strine, the Director of Information Technology and the CIO for the City of Tucson emailed AndyAyre on 21st August 2009 with the following, as a result of some lengthy discussions:

The City provides GIS data to the public, as we do lots of other information. What we are not required to do is provide it in just any format that someone wants. That was the situation in a case I referred to - the data was available on the web, but this company wanted it in a specific format so they could incorporate into their product, which would then be for sale. That reworking we didn't have to do.
If you, or anyone else, enters data into O(pen Street Map that's fine, and if someone uses it for commercial purposes, there's not much the City can do. The point is that the City hasn't used resources to specially support one particular business.
The information on the County web site includes the City data within the county data.
Hope this helps. Have a good time with Open Street Map.

So it appears we have permission to use data from the City. The problem is that it is merged into the County GIS database and access is via County rules.

After discussions with the County it appears possible for us to obtain some data specific to the City of Tucson only, if it it clearly relating only to the City and is provided via the City and not via the County FTP system.

Discussions are ongoing to see what data can be obtained and how. --AndyAyre 17:37, 27 August 2009 (UTC)

Upcoming Events

None scheduled.

What are mapping parties?

Mapping parties are events where anyone can come and participate in the OpenStreetMap project. OpenStreetMap is a free, open source map that can be contributed, edited and used by anyone anywhere. Mapping parties are social events where experienced and new mappers can meet to share and learn more about the project. The events are generally held in a public place, and allow time for discussion, mapping and editing. The event is open to all.

It's fun. It's free. You can help. JOIN THE FREE MAP REVOLUTION!
