Arizona attractions

Posted by nmixter on 17 December 2009 in English (English)

While on vacation in Arizona last week I added areas near Fort Verde, Montezuma Castle and Well and Tuzigoot Monument.

I also added areas around the Apache Trail for Goldfield Ghost Town, Superstition Mountain Museum, Mining Camp Restaurant and some points along the Apache Trail.

I added surface=unpaved to the 20-mile portion of the Apache Trail where it is not paved. I didn't know if I could make it with a small rental car. But it was in good condition, and I had no problems. I guess that is what rental cars are for. I didn't know how far it went so I called the resort at Roosevelt Lake to find out if there was gas nearby.

It's interesting to see the desert areas marked as forests. Technically they are a national forest, but many parts are actually desert scrub. Maybe a landcover import will help there. I also noticed that several of the bodies of water along the Apache trail were missing like Roosevelt Lake and Canyon Lake. Tiger 2009 actually has a good water layer with this data in it. Is anyone interest in uploading it. Or I could do it. Not sure if these would compete with the natural hydrology import I think is being done.

California land cover imports

Posted by nmixter on 4 December 2009 in English (English)

Planning is in progress to add California vegetation land cover shapefiles. The state has some good land cover shapefiles on the Department of Forestry and Fire Protection site. They are sorted by county. The smallest are under a meg while the largest - Fresno - is more than 400 megs. The average size is around 30 to 40 megs. These would be a great addition to OSM since they contain valuable metadata. Once the areas have been added, the state will take on a similar look to states like Georgia and Massachusetts that have had statewide imports done. Another good example of what California can be is the Corine Land Cover.
Check out the [[California Land Cover]] wiki page to learn more.

Tiger 2009 areas

Posted by nmixter on 20 November 2009 in English (English)

I just finished adding the Tiger 2009 area polygon shapefiles for California. The data includes most parks, national forests, cemeteries, commercial areas, some schools, colleges and universities and more. I tried to remove the larger parks and areas to not duplicate existing areas. But some of the smaller parks were repeated and need to be manually removed. Also Tiger uses a weird set of abbreviations which I documented on the [[TIGER 2009]] wiki page. I corrected some of the later ones by opening the OSM file in a text editor and then doing a find and replace for each one. I uploaded all the counties except for Santa Cruz and Los Angeles which have already had imports done in them or have already been mapped. I added the points and water files in the bay area. A lot of these repeat what is on the ground, so I am going to let others add the other ones in their counties if they want. If anyone in the U.S. would like to upload data for their counties but doesn't know how to use the java shp-to-osm, let me know and I can email you the OSM files you can upload in JOSM.

Mount Madonna Park

Posted by nmixter on 8 November 2009 in English (English)

Just updated all the Mount Madonna trails and amenities (rectified from official park map). There were a bunch of Tiger residentials that should have been tracks. Trails include whether horses are allowed or not. 3,615 points total added or modified. It had just a few trails before. Took quite awhile but it was worth getting everything in.

Location: Blackhawk Canyon Trail, Santa Clara County, California, United States of America

Napa farms

Posted by nmixter on 26 October 2009 in English (English)

Just added farm areas from the official Napa County file that we got permission to upload. Many vineyards were added.

Location: Withers Road, Buchli, Napa County, California, CA 94559, United States of America

Mono building footprints

Posted by nmixter on 8 October 2009 in English (English)

I imported all the Mono County building footprints from the county GIS file, one of a handful of counties that have given us permission to use their data. Buildings are always good to have, and I wanted to see how they would look. I think San Diego county is the only other area in California with building imports. Hopefully we can get Santa Clara County buildings and files soon. I saw CAPIL had county zoning and parcel files, but I couldn't find any way to download them.

Unfortunately the upload crashed about half way through so there are a ton of extra points as with Santa Cruz. I will go in and clean them up with JOSM and validator as with Santa Cruz. It just takes forever. Also not all the addresses were in the shapefile, so many of the buildings have a 0 on them. And each of the buildings in a complex has a name, instead of one name for the whole area.

I think I need to increase the amount of memory with JOSM. Also I need to figure out a way to have the outer relations show up in the OSM files. I originally thought it might be a problem with the 2,000 node limit. In the rules file, I just define the outer shapes. I think I saw somewhere the inner relations weren't defined. I think there is a multipolygon. Should I try that?

Bob Jones added

I added Bob Jones University in Greenville, SC to OSM.

San Jose zones

Posted by nmixter on 25 July 2009 in English (English)

I finished zoning the southern portion of San Jose and Los Gatos from 85 south to 17. I will keep moving north.

new lakes in ca

Posted by nmixter on 30 December 2008 in English (English)

I added shapes for Lake Nacimiento and San Antonio Reservoir from Yahoo. They are fairly large bodies of water in central california so I can't believe they hadn
t been added before. There was one hamlet which was located under where one of the lakes was. Not sure what it was but left it there in case it a buried gold mine or underwater city of atlantis or something.

It's beginning to get green outside

Posted by nmixter on 17 December 2008 in English (English)

I added county and state park shapes in Santa Clara, Santa Cruz and San Mateo counties using map rectifier ( It is a great program to use to add landuses that can't be added with GPS. Now the area on the west bay is no longer completely white. It's now got a smathering of green parks throughout. I included the wms rectified image numbers below in case anyone wants to look at them or add extra features, ie trails, restrooms, campsites. Currently I just added the shapes for the parks. I will continue to add additional parks working north toward SF.

South Silicon Valley

Posted by nmixter on 10 September 2008 in English (English)

Continued editing area south of San Jose in Gilroy and Morgan Hill. I've added most of the correct curves to the streets to line them up with Yahoo's images. New lines for streets have been added, but I haven't added names yet. Next to add is features such as golf courses, parks, schools and churches.
