BADB

Big Address DataBase is a series of python scripts that provide a command line interface (cli) to geocode large address databases. The original design was intended for the Rhode Island Enhanced-911 (E-911) Data set, but can be adapted to apply to any dataset.

What can I find here?

• scripts folder: Breaks down each step of the workflow into independent python scripts.
• badb folder: Provides a cli to run workflow set out in scripts. For further detail, refer to the READ.me files contained within each folder.

Set up:

The BADB package relies on poetry. poetry is a tool for dependency management and packaging in Python.
You can learn more about poetry here (If you are struggling to download poetry even after following the documentation, I have some suggestions in the Appendix.)

poetry check    # ensure that you have poetry installed, and that the .toml file is correct  
poetry install    # The install command reads the pyproject.toml file from the current project, resolves the dependencies, and installs them.
poetry build    # The build command builds the source and wheels archives.
poetry shell    		

Now, you can activate the CLI (Command Line Interface) by running the badb command

badb

The script was designed primarily for the E-911 database of Rhode Island. For further exploration, the E-911 data available here.
For further information regarding the SmartyStreets services and API, refer to the documentation Refer to their pricing page for associated costs of generating an API key to run this package! (The scripts make exhaustive searches for accurate outputs, i.e each address may need more than 1 call on the API. Therefore, the unlimited service is highly recommended!)

Getting started:

Going to the terminal and typing:

badb

Shows the list of available command. The instructions to using a particular function can be found by running the --help flag:

badb [command] --help

Demonstration:

Credentials for the SmartyStreets API is stored in path_to_config/config.csv. The expand command to a .csv of addresses at path_to_file/file.csv can be done with the following command:

badb expand -c path_to_config/config.csv path_to_file/file.csv

For efficiency, the expand command only searches for addresses in a single specified US state. The command defaults to searching in Rhode Island. So, if file.csv is composed of addresses of a different state, specificy with the -s or --state flag:

badb expand --state IL -c path_to_config/config.csv path_to_file/file.csv

Appendix

Q: poetry just doesnt seem to be working!

I have personally found the easiest way to install poetry is to use Homebrew. If you do not have Homebrew already installed, paste the following in a macOS Terminal or Linux shell prompt:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

or refer to the following documentation.

If you already have Homebrew installed, you can install poetry with:

brew install poetry

Q: rtree is causing issues!

This is a very common problem, so fear not. If you are having trouble with Rtree after running poetry install, this means that rtree cannot be downloaded. This may be because you are missing a dependency: spatialindex. You can download spatialindex using the following command:

brew install spatialindex
pip install Rtree
