Crowdsourced tool for locating and reporting ALPRs. [View Live Site](https://deflock.org).

## Purpose

I created this project after noticing the mass deployment of ALPRs in cities, towns, and even rural areas in the recent years. It's a massive threat to privacy, and this projects helps shed a light on this issue as ALPRs continue to be deployed to thousands of cities across the US and possibly beyond.

## What it Does

### View ALPRs on a Map
Uses OpenStreetMap data to populate a map with crowdsourced locations of ALPRs, along with their type and direction they face.

The map has become a separate repository, [deflockhopper_maps](https://github.com/FoggedLens/deflockhopper_maps).


### Report ALPRs
Provides instructions for using the [DeFlock App](https://deflock.org/app) or OpenStreetMap's [iD web editor](https://www.openstreetmap.org/edit) to report ALPRs using a standardized tagging system.

### Identify ALPRs
A constantly-growing repository of ALPR makes, models, and tagging instructions for OpenStreetMap, along with images for identifying them.
