Bellingham, Washington building and address import

UPDATE: we're using a different approach instead. Ignore this repo, and go here instead: https://github.com/osmlab/Bellingham-Bldg-Addr

This repository is based on the DC buildings import and the later LA buildings import. There may be some references to DC or LA that have not been switched over yet.

Work in progress, do not use for import yet

Generates an OSM file of buildings per Bellingham census block group, ready to be used in JOSM for a manual review and upload to OpenStreetMap.

The .osm files are in the osm folder and are numbered according the the census block group ID. To find the file you're looking for, see this map of block groups in Whatcom County and find the GEOID of the block group by clicking on it.

No formal import proposal has been made yet. We will follow the import guidelines before any data is imported.

Prerequisites

libxml2 
libxslt
spatialindex
GDAL  

Mac OSX specific install

# install brew http://brew.sh

brew install libxml2 
brew install libxslt 
brew install spatialindex 
brew install gdal 

Ubuntu install

sudo apt-get install libxml2
sudo apt-get install libxml2-dev libxslt1-dev python-dev
sudo apt-get install libspatialindex-dev
sudo apt-get install gdal-bin

Set up Python virtualenv and get dependencies

# may need to easy_install pip and pip install virtualenv 
virtualenv ~/venvs/bellingham-wa-buildings
source ~/venvs/bellingham-wa-buildings/bin/activate 
pip install -r requirements.txt

Usage

Run all stages:

# Download all files and process them into a building
# and an address .osm file per census tract.
make

You can run stages separately, like so:

# Download and expand all files, reproject
make download

# Chunk building and address files by census tracts
make chunks

# Merge building and address files
make chunks

# Generate importable .osm files.
# This will populate the osm/ directory with one .osm file per
# census tract.
make osm

# Clean up all intermediary files:
make clean

Source data

• Buildings http://www.cob.org/data/gis/FGDB_Files/COB_struc_shps.zip
• Address Points http://www.cob.org/data/gis/SHP_Files/COB_land_shps.zip

For future import (not in current phase):

• LIDAR for building heights? See: http://pugetsoundlidar.ess.washington.edu/lidardata/restricted/nonpslc/bellingham2013/bellingham2013.html

Features

• Transforms relevant attributes to OSM tags
• Exports one OSM XML building and address file per census block group
• Handles multipolygons
• Simplifies building shapes

Attribute mapping

Buildings

Each building is a closed way tagged with:

`building=yes`, or:
  - `building=house` if `BLDGTYPE=HOUSE`
  - `building=residential` if `BLDGTYPE=DUPLX`
  - `building=public` if `TYPE=PUBLIC`
  - `building=static_caravan` if `TYPE=TRAILER`
  - `man_made=storage_tank` if `TYPE=RESERVOIR`
`name=NAME` # if available
`building:levels=NUMFLOORS` # integer values, or 0.5, 1.5, 2.5, 3.5
`start_date=YRBUILT` # if > 1800 (there is one erroneous value to filter out)

(All entities in CAPS are from COB_struc_Buildings shapefile.)

Addresses

Addresses are only imported if they intersect a building. If a building contains only one address, the address will be added to the building object. If a building contains more than one address, the addresses will be imported as separate nodes.

`addr:housenumber=ADDR_NUM`
`addr:street=STREET_NAM`  # with direction prefixes and postfixes expanded
`addr:unit=ADDR_SUITE`    # if available
`addr:postcode=ZIP-PLUS4`

(All entities in CAPS are from COB_land_AddressPoints shapefile.)
