Hm, source addresses are not capitalized, I am using the STREET_BODY + STREET_FULL_SUFFIX as a street name. "STREET_NUMBER":"72", "FULL_STREET_NAME":"Addington Rd", "STREET_ID":27,"STREET_PREFIX":" ", "STREET_BODY":"Addington", "STREET_SUFFIX_ABBR":"Rd", "STREET_FULL_SUFFIX":"Road", "STREET_NUMBER_SORT":72, "MAILING_NEIGHBORHOOD":"West Roxbury" "ZIP_CODE":"02132" > - How are you dealing with multiple addresses per building I am adding a local note highlighting that the the same way has more than one address to locate buildings that need to be split according to parcel map/retrace from Bing/MassGIS Orthoimagery. Such buildings are generated into separate -fixmes.osc files. > - How are you dealing with multiple buildings per address. Since only a single location is provided for a building (RELATION_TYPE=1) there is no multiple matching buildings per address. On a side note that may require additional survey on location in case a multipolygon is required. We can't deduce that from the source data. > - Unless you are working full time on this two weeks seems like not > enough time, it is 380,000 addresses. Please see the wiki page linked - https://wiki.openstreetmap.org/wiki/I mport/Boston_Street_Address_Management_(SAM)_Import there are about 5000 with issues out of 64K existing OSM buildings (~8%). At least until those two missing neighborhoods are found. Even if only unique buildings are imported it will yield a 92% increase of accuracy for building locations. The remaining time will be spent tweaking these 5000 buildings. And yes, I'm basically working on this full time. > - The source data contains the building heights, you might want to > import that in too. Only number of floors is provided (which can be 2.5), not the height itself. It is easy to add this though. My initial reading of https://wi ki.openstreetmap.org/wiki/Key:building:levels suggested that building:levels is not useful w/o height. > - I would like to see a sample osm/osc files.
