Hello. I'm a relatively new mapper, and I'm mostly working in upstate NY,
where there is not great coverage outside of roads. I've been adding houses
manually, but progress is slow and inefficient this way.
I found that NYS publishes GIS data in their "Clearing House", and one of
the data sets available is address points:
https://gis.ny.gov/gisdata/inventories/details.cfm?DSID=921
I opened the data in JOSM, and they look spatially accurate, for the most
part (I noticed some points are off for addresses that don't have recent
satellite imagery available).
Reading up on the import guidelines, I can see that the license is
important. However, I am not able to see anything that explicitly states
one way or another what kind of license the data sets are distributed
under, and this whether or not it is compatible with the ODBL. I wanted to
ask if perhaps anyone else had investigated these data sets in the past,
and what their findings were. If not, is the next step to email someone and
ask?
I don't have anything like an extensive plan for carrying out an import,
which is why I did not include the "authoritative" imports mailing list
yet. However, at a high level, as I am a software engineer by trade, my
plan is to write a script that reads the shapefiles and an .osm file dump
as input, does the attribute to tag transformations, and deduplicates with
the existing data by excluding any address points that already exist in any
OSM object with equivalent addr:* tags (it might also be necessary to
inspect all associatedStreet and street relations). It would produce an
.osm as output that contains nodes with just addr:* tags. This can then be
opened in JOSM and merged into the standard data layer. I'd probably start
with a single county and go from there.
As a disclaimer, I do this in my free time, which is in short supply, so
progress on this would likely be slow. However, I would love if everyone
could just search for any address and find it.
