Offers an unified API for multiple geocoders like Addok, OpenCageData, Here, Google based on countries distribution. The main idea of this API is to define some specific geocoder for some countries and a fallback geocoder for all other countries. Build in Ruby with a Grape REST swagger API compatible with geocodejson-spec. Internal use of Geocoder Gem.
You need to install prerequisite packages :
apt-get install -y git build-essential zlib1g-dev gdal-bin zlib1g libsqlite3-mod-spatialite libsqlite3-dev libspatialite-dev
If you need to create a kml, install package containing ogr2ogr exec from system package (GDAL).
In geocoder-api as root directory:
bundle install
# Download and build French KML boundaries
(cd contrib && sh ./osm2france+dom-geojson.sh)
docker compose up -d
By default it creates data for 2A corsica (317 Kb)
./initialize.sh
To build other department pass it as an argument (full for France)
./initialize.sh 33
Access it at http://localhost:8558
bundle exec rackup -p 8558
If you need to work with local built addok images and api
docker compose -f docker-compose.yml -f docker-compose-build.yml build
The countries data sanitizer/countryInfo.txt for supported languages can be update from https://download.geonames.org/export/dump/countryInfo.txt . The data is under creative commons attributions from GeoNames.
The API is defined in Swagger format at http://localhost:8558/swagger_doc and can be tested with Swagger-UI https://swagger.mapotempo.com/?url=https://geocoder.mapotempo.com/swagger_doc
The search can be done by full text free form or by fields. Prefer fields form when you have an already splitted address. For any form, the country is a required field, use a simple country name or code in two or three chars.
Search can be guided by proximity. Set latitude and longitude of an close location.
Retrieve the closest address from latitude and longitude position by GET request.
Unitary requesting convert only one address or coordinates at once using GET request.
