Here are some details about a small piece* of one of these Kern County tiles:
1667KB OSM XML
6036 nodes:
- 5702 nodes that are part of building ways
- 256 trees
- 69 highway nodes
525 ways
- 489 building ways
- 34 highways
That is to say this medium-density (4-5 houses per acre) residential
neighborhood would have 78 nodes (1.3% of current) and 36 ways (6.9% of
current) without the building outlines and trees. The OSM XML would be
31KB (1.9% of current).
* 0.5 mi x 0.5 mi (800 m x 800 m) at minlat='35.3979622'
minlon='-119.1277814' maxlat='35.4052032' maxlon='-119.1188657'
Here's a smaller (1/4 size) clip of an even denser 5-lots-per-acre
neighborhood* with detached garages (i.e. 2 buildings per lot):
660KB OXM XML
1839 nodes:
- 1482 building way nodes
- 212 tree nodes
- 103 landuse way nodes
- 15 highway nodes
354 ways:
- 329 building ways
- 15 landuse ways
- 8 highways
It would have 15 nodes (0.8% = 1/123rd of current) and 8 ways (2.3% =
1/44th of current) without the building outlines, landuses (for consistency
with the other example, which just had one landuse way) and trees. The OSM
XML would be 9KB (1.4% = 1/73rd of current).
* 0.25 mi x 0.25 mi (400 m x 400 m) at minlat='35.3648359'
minlon='-119.0341401' maxlat='35.3686942' maxlon='-119.0292585'
