OA Machine

Scripts for performing ETL on a single source, passing the end result to the openaddresses/batch service Uses OpenAddresses data sources to work.

Status

This code is being used to process the complete OA dataset on a weekly and on-demand basis, with output visible at batch.openaddresses.io.

These scripts are wrapped by the main openaddresses/batch processor.

Use

It is highly recommended to use this tool via the provided docker file - using an unsupported/untested version of GDAL (the core geospatial library) will result in widely varying results.

Should you run this in a virtual env, install Tippecanoe and GDAL before use.

Docker

docker build -t batch-machine .
docker run -it batch-machine bash

Or to direct your generated output to a folder on the host machine, use Docker Volumes.

Given an input file like this residing in the current directory inside Docker:

{
    "schema": 2,
    "coverage": {
        "country": "ca",
        "state": "nb"
    },
    "layers": {
        "addresses": [{
            "name": "state",
            "data": "http://geonb.snb.ca/downloads/gcadb/geonb_gcadb-bdavg_shp.zip",
            "protocol": "http",
            "compression": "zip",
            "conform": {
                "number": "civic_num",
                "street": "street_nam",
                "format": "shapefile",
            }
        }]
    }
}

You can create an output folder and then run the batch process on the desired layer's key and its child object's name as arguments:

mkdir my-output
openaddr-process-one --skip-preview --layer addresses --layersource state example.json my-output
