GeoJSON

GeoJSON is an open standard format for encoding geographic data structures using JavaScript Object Notation (JSON). It is widely used for web-based mapping applications, APIs, and data exchange between GIS platforms.

• Point: A single location (e.g., a sample site or well location)
• MultiPoint: Multiple related points
• LineString: A connected sequence of points forming a line
• MultiLineString: Multiple line features
• Polygon: A closed area defined by a ring of coordinates
• MultiPolygon: Multiple polygon features
• GeometryCollection: A mix of geometry types

• type: "FeatureCollection" (most common top-level type)
• features: Array of Feature objects
• Each Feature has: type, geometry, and properties (attributes)
• Coordinates are in longitude, latitude order (WGS84 by default)

Advantages: - Human-readable text format - Native support in JavaScript and web applications - Lightweight and efficient for web transfer - Supported by virtually all modern GIS platforms - No need for multiple files (single file format) - Easy to parse and generate programmatically

Limitations: - No built-in support for coordinate system specifications (assumes WGS84) - Less efficient for very large datasets compared to binary formats - No built-in topology or spatial indexing - Limited data type support compared to geodatabases

Common uses: - Web mapping applications (Leaflet, Mapbox, Google Maps) - API responses for spatial data services - Data exchange between platforms - Mining claim boundary visualization in web dashboards - Lightweight spatial data distribution
