[Deprecated for Pelias] Geocoder based on Elasticsearch

Debian has a custom version of pip, which broke in testing: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=786580
see #1
Endpoint | Description |
---|---|
/address/<city>/<streetname> | Return all housenumbers with locations on the given street, in given city. |
/address/<city>/<streetname>/<housenumber> | Return location for given housenumber in given street and city. |
/suggest/<search term>[?city=Cityname[&city=Anothercity]] | Return all kinds of objects with given term anywhere in the name. Streetnames are returned per each city and including number of addresses in the street. All other objects include location. Every type is in a separate list with a field name in result object. Also returns streetnames with Levenshtein distance of two. Query parameter city can be specified one or more times to limit suggestions to within those cities. |
/reverse/<lat>,<lon>[?zoom=8] | Return nearest address for given WGS84 coordinates. If given zoom level is under 8, then returns municipality, not an address. |
/interpolate/<streetname>/<housenumber> | Return an estimated location for an address interpolated from road network data. |
/meta | Return metadata about the API. Currently the date when the data was last updated in "updated" field in ISO 8601 format. |
Search for "sampsantie", you will see that city is "helsinki". Should be "Helsinki"

http://www.elastic.co/guide/en/elasticsearch/guide/current/_important_configuration_changes.html needs to be read carefully when setting up the real thing.
Why such address exists?
http://matka.hsl.fi/geocoder/search/helsinki/kivikallio
Example: Virsutie 5 finds Virsutie 4-6.
Now these return response in different format:
Unify response.
All fields in "/search/address" should be included to "/search/address/number"
Document how implementations works see #1
Let's start by writing documentation to git repo readme.
Results are ordered as described in #1
As a quick fix to get UI more responsive to search, reduce amount of returned results to 10 per returned type.
Now there is problem that UI basically jams when trying to parse too many results.

Check that languages work as described in #1
Either elastic-wait needs to be modified to check shard status, or app.py needs to handle 503 gracefully.
We should get from OSM:
e.g.
Opastinsilta 1
Opastinsilta 2
Opastinsilta 3
...
Opastinsilta 10
Start by doing some user stories about the actual usage. After this, we will decide how to proceed with geocoding.
See #1
If we can't get accurate address information for the whole country, we need to use the road/street data from National Land Survey with interpolation.
Often OSM has data in only one language, and does not tell what that language is.
See #1
Currently GTFS has only Finnish
For example Opastinsilta 6a is shared with HSL and local pub. Return both or just a centroid. Currently geocoder returns one 6a and one 6A each...
Pelias demo has problems with data import, so we need a customized version to test the existing features
