## Introduction to OpenStreetMap

OpenStreetMap (OSM) is a collaborative project to create a free, editable map of the world. Unlike proprietary maps, OSM relies on contributions from volunteers. Adding a website tag to a local shop or amenity is a simple yet impactful way to start. This small edit can enhance the map's usefulness for millions of users worldwide.

## Why Add a Website Tag?

A website tag in OSM provides a gateway to essential information about a location. Official websites often include details like phone numbers, opening hours, and email addresses. By adding this tag, you make it easier for others to access and verify this data. It’s a beginner-friendly way to contribute meaningfully.

## Getting Started with JOSM

JOSM (Java OpenStreetMap Editor) is a powerful tool for editing OSM data. While simpler in-browser editors exist, JOSM offers advanced features and plugins. Download the 365 MB application for your operating system and install it. JOSM’s flexibility makes it ideal for both beginners and experienced mappers.

## Filtering OSM Data

Use JOSM to filter OSM data and display only shops and amenities without website tags. Apply the filter 'name=* ((amenity=* 'addr:housenumber'=*) | shop=*) -website=* -'contact:website'=*'. This narrows down your area of interest (AOI) to places needing updates, making your task more efficient.

## Using the Website Wizard Plugin

The Website Wizard plugin simplifies the process of adding website tags. Once installed, it automates much of the work, allowing you to focus on verifying information. This plugin is particularly useful for bulk edits, saving time and effort while maintaining accuracy.

## Example Contribution

In Seattle’s Wallingford neighborhood, one contributor added 66 new website tags in a single changeset. This demonstrates how quickly small edits can accumulate into significant improvements. Such contributions enhance the map’s utility for both locals and visitors.

## Expanding Your Contributions

After mastering website tags, you can tackle other missing data, such as phone numbers or opening hours. Modify your filter to identify places with incomplete information. Each contribution brings OSM closer to becoming the most comprehensive map available.

## The Bigger Picture

With over 1 million shops in the U.S. alone, OSM relies on a growing community of contributors. By spreading the word and encouraging others to join, you help accelerate the project’s progress. Every edit, no matter how small, pushes OSM toward its goal of being the world’s greatest map.
