Free GeoJSON Editor – Draw on Map and Export GeoJSON Online

If you work with maps, routes, or geospatial data, you’ve likely come across GeoJSON. It’s one of the most popular formats for storing geographic shapes and points used in mapping and location-based applications. GeoJSON allows you to define locations, lines, areas, and boundaries in a format that’s both machine-readable and easy for developers to work with. However, editing or generating GeoJSON by hand can be time-consuming and error-prone.

To make it easier to work with, we’ve built a GeoJSON Editor — an online tool that lets you draw directly on a map and instantly generate valid GeoJSON data. Whether you’re building a route planning tool, drawing geofencing boundaries, or marking service zones, this editor helps you do it visually without writing a single line of code. No complex software or coding needed.

In this blog, we’ll explain what GeoJSON is, why a visual editor matters, and how you can use our free tool to simplify your workflow.

What is GeoJSON?

GeoJSON is a data format based on JSON (JavaScript Object Notation) that is used to represent geographical features. It helps store information like:

• Points (e.g., store location, delivery address)
• Lines (e.g., roads, routes)
• Polygons (e.g., city boundaries, service areas)
• Multi-part shapes (e.g., multiple delivery zones)

It’s lightweight, easy to read, and works well with web mapping libraries like Leaflet, Mapbox, and NextBillion.ai’s Maps SDK.

Here’s a basic example of a GeoJSON point:

{
  "type": "FeatureCollection",
  "features": [
    {
      "id": "44075eee7fa8cfa057db5c6abb37c910",
      "type": "Feature",
      "properties": {},
      "geometry": {
        "coordinates": [
          [
            [
              -74.00552662921885,
              40.72761248068247
            ],
            [
              -74.00446145443892,
              40.74088528883618
            ],
            [
              -73.97818714319975,
              40.73998856088588
            ],
            [
              -73.97996243449946,
              40.726446499408354
            ],
            [
              -73.99392805939277,
              40.71666939115812
            ],
            [
              -74.00552662921885,
              40.72761248068247
            ]
          ]
        ],
        "type": "Polygon"
      }
    }
  ]
}

  

GeoJSON is the preferred format for developers building logistics, mobility, GIS, and field service applications.

Why You Need a GeoJSON Editor

Creating GeoJSON manually can be painful. Even if you’re familiar with coordinates and data structures, typing and validating it line-by-line is slow and error-prone.

A GeoJSON editor lets you:

• Visualize while you create – See your points, lines, and areas on a real map
• Draw intuitively – Use your mouse instead of calculating lat/lon pairs
• Avoid syntax errors – The tool generates valid GeoJSON for you
• Experiment faster – Try different shapes or boundaries without restarting code

This is especially useful for:

• Developers testing geofencing or routing logic – You can quickly simulate different zone configurations or route paths without building a full UI.
• GIS professionals defining custom zones – Drawing complex polygons visually speeds up the zoning, planning, and auditing process.
• Operations teams drawing service or delivery areas – Marking zones on a map helps logistics and dispatch teams communicate clearly and plan better.
• Urban planners or mobility startups – Define and refine transport corridors, traffic zones, or safe walking areas visually.
• Researchers or analysts working with location data – Plotting raw data into GeoJSON lets you test location-based models or filter spatial data.

In short, it removes the friction from working with location data. Instead of writing and rewriting code or using heavyweight GIS tools, you get a clean, browser-based experience that focuses purely on what you want to create — usable, valid geographic data.

Real-World Use Cases

Wondering how this fits into your workflow? Here are practical ways GIS and logistics professionals use this tool, including relevant pain points it addresses and the benefits it provides:

1. Geofencing Zones

Create virtual boundaries around specific locations to trigger entry/exit events or alerts. Manually defining zones can lead to inaccuracies and inconsistency across teams. Drawing geofences visually ensures accuracy and speeds up implementation in apps using geofencing APIs.

2. Delivery or Pickup Areas

Define custom serviceable zones for food delivery, package pickup, or on-demand services. Inconsistent zone definitions often lead to failed deliveries or customer confusion. Drawing zones visually ensures better operational planning and a smoother customer experience.

3. Fleet Route Planning

Design optimized or custom-preferred delivery routes and visualize vehicle paths. Manual route setup and testing can be slow and error-prone. Draw and export routes in GeoJSON format for direct input into route optimization or navigation engines.

4. Territory Mapping

Visualize sales, support, or operational territories for better resource allocation. Static maps in spreadsheets or PDF formats don’t support easy adjustments. Quickly draw and adjust territories to reflect real-time business changes or growth strategies.

5. Field Service Planning

Field teams can draw observed routes or areas from the field and export them. Lack of simple tools delays post-collection mapping or requires training. Minimal learning curve with real-time drawing and export for non-technical users.

These shapes can be fed directly into your backend systems, APIs, or visualization dashboards to power real-world operations.
