GeoJSON
A widely used, text-based open standard format for encoding geographic data structures, facilitating data exchange and visualization.
What does GeoJSON represent?
A popular open-standard format called GeoJSON uses JavaScript Object Notation (JSON) to encode a range of geographic data types. In a straightforward, legible language style, it depicts geographical features like points, lines, polygons, and the attributes that go along with them.
Web mapping apps, APIs, and GIS tools frequently use GeoJSON, which is made to store and exchange geographic data online. The following essential components are supported:
Geometry types: Point, LineString, Polygon, MultiPoint, MultiLineString, and MultiPolygon.
Feature: A single spatial object with associated attributes.
FeatureCollection: A group of features in one file.
For example, with descriptive metadata, GeoJSON can depict a city's border, a river's course, or the positions of landmarks. It is perfect for showing spatial data in interactive maps and web-based GIS applications because of its compatibility with web technologies.

A popular format for using JSON to encode geographic data structures is called GeoJSON. It facilitates the sharing and visualization of spatial data on web maps by representing features such as points, lines, and polygons along with their attributes. For web mapping, spatial analysis, and geospatial applications, GeoJSON is perfect due to its ease of use and compatibility with programs like Leaflet, Mapbox, and GIS software.
GeoJSON is a popular lightweight data format for JSON-based encoding of geographic data structures. It is perfect for web mapping, GIS applications, and data interchange between systems since it depicts features like points, lines, and polygons together with their attributes. Spatial data may be easily stored, shared, and shown because to its ease of use and compatibility with numerous systems.
While both GeoJSON and TopoJSON are formats for recording geographic data, their efficiency and structure vary. GeoJSON is straightforward and extensively supported, although it frequently has bigger file sizes because it explicitly encodes features like points, lines, and polygons. Although it necessitates extra processing to read, TopoJSON reduces redundancy and file storage by encoding geometries as shared arcs, making it perfect for online mapping and huge datasets.
GeoJSON is a lightweight format for recording geographic data, and Leaflet is a well-known JavaScript framework for interactive maps. GeoJSON data may be readily loaded and shown on a map by adding it as a layer using Leaflet. This enables you to bind popups for interactivity, visualize points, lines, and polygons, and style them with unique colours or icons. Making dynamic, interactive maps is simple and effective when GeoJSON and Leaflet are combined.
