GeoJSON is a format for encoding a variety of geographic data structures. It is designed to be a language-agnostic data interchange format. This tutorial will give you a basic understanding of GeoJSON and how to use it.
What is GeoJSON?
GeoJSON is a format that can encode various geographic data structures, including points, lines, and polygons. It is often used for web mapping and geospatial data interchange.
Key Features
- Data Structures: GeoJSON supports various data structures, including Points, Lines, and Polygons.
- Human and Machine Readable: It is designed to be both human and machine readable.
- Extensible: GeoJSON is extensible and can be used to store additional information.
Example
Here is a simple example of a GeoJSON object representing a point:
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [102.0, 0.5]
},
"properties": {
"name": "Dhaka"
}
}
In this example, the point is located at coordinates [102.0, 0.5], and it has a property called "name" with the value "Dhaka".
