[Talk-us] Kern County progress

Treating this as a new import, I have a few questions

 

Is there a page on the wiki with the information called for in
http://wiki.openstreetmap.org/wiki/Import/Guidelines#Document_your_import_on
_the_wiki? There is the Kern County page, but that is a page for the county,
not a page for an import.

 

What software do you plan to use to convert shapefiles to OSM?

 

Can you post an example of the data in .osm format, that way we can see how
the data tagging as well as the accuracy is.

 

The metadata for the Bakersfield source contains the following clause

 

You agree not to provide a copy or partial copy of any data

to any other party, including consultants under

contract with you, without disclosing that the copy or partial

copy was obtained from The City of Bakersfield and

without attaching a duplicate of these Terms and Conditions.

 

I know that you had informally obtained different permissions for some data
but that it wasn't particularly well documented. Could you obtain clearer
permission, including for the data previously imported.

Yes, I guess it would be considered as a new import since it includes new
data not originally included from the city. But it is a selective import
since not all the data is new. I plan to do it in several small uploads so I
can verify the accuracy.

> 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.

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.

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.

well.

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.
