🌍 Understanding GeoJSON Documentation

GeoJSON is a widely used format for encoding geographic data structures. Below is a guide to help you grasp its core concepts and usage:

📘 What is GeoJSON?

GeoJSON is an open standard format for representing vector features on a map with geographic coordinates. It is based on JSON and is commonly used in web mapping applications.

  • Key Features:
    • Simple, lightweight structure
    • Supports points, lines, polygons, and multi-geometry types
    • Encodes spatial data with coordinates and properties

📚 GeoJSON Document Structure

A GeoJSON document typically includes:

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "Polygon",
        "coordinates": [[[x1,y1],[x2,y2],...]]]
      },
      "properties": {
        "name": "Example Polygon",
        "population": 1000
      }
    }
  ]
}
  • Components:
    • type: Specifies the feature type (e.g., Feature, FeatureCollection)
    • geometry: Defines the spatial shape
    • properties: Stores non-spatial attributes

📌 Common Use Cases

  1. Mapping Applications - Display geographic features on interactive maps
  2. Geospatial Analysis - Analyze spatial data patterns
  3. Data Exchange - Share geographic data between systems
