GeoJSON Viewer
Open GeoJSON files on a large interactive map. Explore points, lines and polygons, inspect properties, and export your geographic data.
Map & satellitePoints, lines & polygonsProperties & stylesLocal file processingUp to 10 files • 10 MB per file • 100,000 coordinates and 5,000 geometry parts in total.
File contents stay in your browser. External map providers receive your IP address and requested map areas. Data URLs and images referenced in properties are not fetched.

Statistics reflect visible geometry parts. Length and polygon area are spherical estimates, not surveying measurements. Polygon holes are subtracted; overlapping polygons are counted separately. Altitudes are preserved as supplied; the map is a 2D view.
Loaded files
Toggle files or individual geometry parts. Turn off “Property colors” to use each file’s color.
Feature inspector
Search filters the table only. Use the checkboxes to change the map and exports.
| Show | Name | Geometry | Source type | Coordinates | Map |

Exports include visible geometry parts. GeoJSON export keeps original properties and IDs on each visible part, including nested property values. Multipart geometries and GeometryCollections become individual Point, LineString or Polygon features. Null and empty geometries, bounding boxes and foreign members are omitted. KML export uses separate placemarks and serializes complex properties as text. PNG contains geometry only, without background imagery.
Supported GeoJSON and limits
Import a FeatureCollection, one Feature, or a geometry object. Supported geometry types: Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon and GeometryCollection. Polygon holes are retained.
Use WGS84 coordinates ordered as longitude, latitude, optional altitude. Legacy CRS declarations and projected coordinates are rejected. Polygon rings must be closed. Positions must have two or three numeric values. Null and empty geometries have no map representation.
The viewer checks structure and coordinate ranges, not complete RFC compliance or polygon topology. Self-intersections and areas larger than a hemisphere can produce unreliable measurements. Dateline-crossing shapes should be split at the antimeridian before import. Input styling recognizes six-digit hex stroke, fill and marker-color properties, plus numeric stroke-width, stroke-opacity and fill-opacity.
GeoJSON Viewer: View GeoJSON Files Online
A GeoJSON Viewer is a simple online tool that lets you open and view GeoJSON files directly on an interactive map. It is useful for checking locations, boundaries, routes, points, and other geographic data without installing complicated GIS software.
You can upload a GeoJSON file or paste GeoJSON data into a viewer and see the geographic features on a map. This makes it much easier to understand your data than reading raw JSON code.
What Is GeoJSON?
GeoJSON is a popular format used to store geographic information in a simple JSON-based structure. It is commonly used by mapping applications, websites, APIs, GIS software, and developers.
A GeoJSON file can contain different types of geographic features, including points, lines, polygons, and collections of multiple features.
Used for locations such as towers, airports, shops, cities, or other specific places.
Used for roads, routes, paths, or other linear features.
Used to represent an area, boundary, zone, or region.
Used when a GeoJSON file contains multiple geographic features.
What Is a GeoJSON Viewer?
A GeoJSON Viewer displays the geographic information contained in a GeoJSON file on an interactive map.
Instead of looking at longitude, latitude, and JSON code, you can see the actual points, lines, and areas visually on a map.
For example, if your GeoJSON file contains a polygon representing a service area, the viewer can draw that area on the map so you can quickly check its location and shape.
How to Use a GeoJSON Viewer
1. Open the GeoJSON Viewer
Open the GeoJSON Viewer in your web browser. No complicated GIS software is required for basic viewing.
2. Upload or Paste GeoJSON Data
Upload your .geojsonor compatible JSON file, or paste your GeoJSON data into the viewer if the tool supports it.
3. View the Data on the Map
The viewer reads the coordinates and geographic features and displays them on the map.
4. Explore the Map
Zoom in, zoom out, move around the map, and inspect your geographic features.
Why Use a GeoJSON Viewer?
A GeoJSON Viewer is useful when you want to quickly check geographic data without opening professional GIS software.
- Check whether coordinates are correct.
- View property or land boundaries.
- Inspect GPS data.
- Check routes and paths.
- View city or administrative boundaries.
- Review telecom coverage areas.
- Inspect GIS data.
- Test GeoJSON generated by an application or API.
GeoJSON Coordinates: Longitude and Latitude
One important thing to remember when working with GeoJSON is the order of coordinates.
For example:
[77.5946, 12.9716]In this example, 77.5946is the longitude and 12.9716is the latitude. Using the wrong coordinate order can place your feature in the wrong location.
GeoJSON Point Example
A simple GeoJSON point can represent a single geographic location.
{ "type": "Point", "coordinates": [77.5946, 12.9716]}When this data is loaded into a GeoJSON Viewer, the point can be displayed on the map at its geographic location.
Viewing GeoJSON Polygons
GeoJSON can also represent an area using a polygon. Polygons are useful for displaying boundaries and geographic zones.
Common Examples
- Property boundaries
- Districts
- Service areas
- Coverage zones
- Land parcels
Why Use a Viewer?
A viewer draws the polygon on an interactive map, making it easier to understand the size, shape, and location of the area.
GeoJSON Viewer for GIS Data
GIS professionals and students often work with geographic information from different sources. A GeoJSON Viewer provides a quick way to inspect this information on a map.
It can be useful when working with data exported from GIS applications, mapping APIs, GPS applications, or custom software.
For advanced GIS analysis, professional GIS software may still be required. However, for quickly checking a GeoJSON file, an online viewer can save time.
GeoJSON Viewer for Developers
Developers often use GeoJSON with JavaScript mapping libraries and web mapping applications. A viewer can help check whether the generated data is displayed correctly.
- Check whether coordinates are valid.
- Confirm features appear in the correct location.
- Check polygon shapes and boundaries.
- Verify routes and lines.
- Check multiple features in a FeatureCollection.
- Inspect GeoJSON before using it in a web application.
Is GeoJSON the Same as JSON?
GeoJSON is based on JSON, but it is specifically designed for geographic data.
Regular JSON can store many types of structured information, while GeoJSON follows a defined structure for geographic features such as points, lines, and polygons.
Does a GeoJSON Viewer Require Installation?
An online GeoJSON Viewer normally does not require any software installation. You can open it in a modern web browser and load your GeoJSON data directly.
GeoJSON Viewer vs. GIS Software
A GeoJSON Viewer is mainly designed for quick viewing and checking of geographic data.
Professional GIS software provides advanced features such as editing, spatial analysis, data conversion, layer management, and detailed mapping tools.

FAQ on GeoJSON Viewer
A GeoJSON Viewer is an online tool that displays geographic data from a GeoJSON file on an interactive map. It helps you view points, lines, polygons, and other geographic features.
Yes. An online GeoJSON Viewer can display a GeoJSON file directly in your web browser without requiring professional GIS software.
Most GeoJSON viewers are designed to work with .geojson files and JSON files that contain valid GeoJSON data.
GeoJSON normally uses longitude first and latitude second. For example, [77.5946, 12.9716] represents longitude 77.5946 and latitude 12.9716.
Yes. GeoJSON supports polygons and multi-polygons. They can be used to represent boundaries, zones, land areas, service areas, and other geographic regions.
