GIS File Formats & Spatial Interoperability
Standards and technical parsing guides for GeoJSON, KML, GPX, Shapefiles, and CSV data.
Geographic Information Systems (GIS) rely on standardized spatial interchange formats to store geometry and attribute properties. RFC 7946 GeoJSON provides modern JSON web interoperability, OGC KML powers Google Earth visualization, GPX provides GPS activity exchange, and CSV enables spreadsheet coordinate plotting.
Core Concepts & Learning Progression
Vector Geometry Types
Points, LineStrings, Polygons, MultiPolygons, and GeometryCollections.
Web GIS with GeoJSON (RFC 7946)
JSON structure, FeatureCollections, and the [Longitude, Latitude] coordinate order standard.
XML Formats: KML & GPX
Keyhole Markup Language for Earth mapping and GPS Exchange Format for activity tracks.
In-Browser Client-Side Processing
Parsing multi-megabyte spatial files in Web Workers with zero server upload.
Essential Technical Definitions
GeoJSON
An open standard format designed for representing simple geographical features along with their non-spatial attributes.
KML / KMZ
Keyhole Markup Language, an XML notation for expressing geographic annotation and visualization.
GPX
GPS Exchange Format, an XML data format for GPS track logs, waypoints, and routes.
Shapefile
Esri vector storage format consisting of a bundle of at least three core files (.shp, .shx, .dbf).
