What is WKT and GeoJSON?

WKT (Well-Known Text) is a text markup language for representing vector geometry objects. It's a standard format used in GIS software, databases (like PostGIS), and spatial data exchange.

GeoJSON is a JSON-based format for encoding geographic data structures. It's widely used in web mapping applications and provides a more verbose but human-readable representation of geometries.

Key differences:

• Format: WKT is compact text, GeoJSON is JSON-based
• Usage: WKT for databases/GIS, GeoJSON for web applications
• Structure: WKT is simpler, GeoJSON includes properties and metadata
• Support: WKT in spatial databases, GeoJSON in JavaScript libraries

WKT Format Examples

WKT represents geometries as text strings:

• POINT: POINT(30 10)
• LINESTRING: LINESTRING(30 10, 10 30, 40 40)
• POLYGON: POLYGON((30 10, 40 40, 20 40, 10 20, 30 10))
• MULTIPOINT: MULTIPOINT((10 40), (40 30), (20 20))
• MULTILINESTRING: MULTILINESTRING((10 10, 20 20), (15 15, 30 15))

WKT is widely supported in spatial databases like PostGIS, MySQL Spatial, and Oracle Spatial.

GeoJSON Format Examples

GeoJSON represents geometries as JSON objects:

{
  "type": "Point",
  "coordinates": [30, 10]
}

GeoJSON can include feature properties and is the preferred format for web mapping libraries like Leaflet, Mapbox GL, and OpenLayers.

Common Use Cases

Convert between WKT and GeoJSON for:

• Database Import/Export: Transfer spatial data between PostGIS and web apps
• Web Mapping: Convert WKT from databases to GeoJSON for visualization
• Data Migration: Move data between different GIS systems
• API Integration: Transform geometry formats for different services
• Validation: Check geometry validity in both formats

Supported Geometry Types

This converter supports all standard geometry types:

• Point, MultiPoint
• LineString, MultiLineString
• Polygon, MultiPolygon
• GeometryCollection

Both 2D and 3D coordinates are supported. The converter automatically handles coordinate transformations and validates geometry structure.
