It's good to see some progress made on cleaning these up.

 

Just be clear, are you proposing a new import at this time?

Subject: [Talk-us] Kern County progress

 

I have begun cleaning up the area around Kern County, California. It is
starting to not only look better but be less cluttered.
I originally imported landuse data from both Kern County and the City of
Bakersfield. Some areas from these two agencies overlapped around
Bakersfield, and I have been going through and trying to remove these. The
city data were quite good and included landuse areas, buildings, parks and
even individual trees within the city. The county data tended to be generic
in several places. It also was slightly misaligned in spots particularly in
the rural areas, possibly due to the projection it was created with by the
county.
I have been going through and systematically deleting the redundant areas
and breaking down the over used landuse=farm and landuse=residential tags
into more specific areas. And in the process, I have been covering some of
the ugly white space that has remained empty.
A lot of the areas are now natural=heath. There is not really any good way
to differentiate between meadow and heath areas. Still seems like they can
be used interchangeably sometimes. I've been trying to use meadow for an
area that can be used for grazing. I just started using the heath tag for
open areas generally on areas east of Highway 5. It's not a perfect option
but at least it kind of matches the work others have done around Las Vegas
and in the desert.
I've been trying to integrate the existing Kern County data with the FMMP
farm data, which I have imported for other counties around the state as
well. 

As part of the cleanup, I am adding some new buildings in Bakersfield from
city data. I am only adding new building that have been added since the
original import and verifying that they don't exist to avoid dups. Probably
less than 1,000 total new buildings. Originally, I included bak:fac_type1,
bak:fac_type2 and bak:fac_type3 tags on some buildings to correspond to tags
in the data. These are not needed and can be removed en mass by a script in
the future. I am leaving those tags out and incorporating them into the
building= tag (ie building=residential, building=commercial) for new
buildings.
I also created a long overdue Kern County page on the wiki to keep track of
the changes (http://wiki.openstreetmap.org/wiki/Kern_County,_California).


Thanks to everyone who has contacted me to help out with the cleanup and
offered advise. If anyone is interested in helping or has any suggestions,
feel free to jump in or let me know.
Nathan,
