GeoJSON, GPX & TopoJSON

GeoJSON is the primary vector format for AugmentCity. Files in GPX and TopoJSON format are automatically converted to GeoJSON during import.

GeoJSON​

GeoJSON is a widely supported open format for geographic vector data. It stores points, lines, and polygons together with their attribute data in a single .geojson file.

Importing​

  1. Open the Layers panel and click +.
  2. Select Import file and choose your .geojson file (max 100 MB).
  3. AugmentCity detects the geometry type and applies a default style automatically.
  4. The layer appears in the panel immediately.

What to expect​

  • All feature properties become available in the Style Editor for color mapping and labeling.
  • If the file contains a mix of geometry types (e.g. points and polygons), all are imported together.
  • Large files (> 10 000 features) may take a few seconds to load in the viewer.

GPX​

GPX (GPS Exchange Format) is commonly used for tracks, routes, and waypoints recorded by GPS devices.

GPX files are converted to GeoJSON automatically during import. The resulting layer contains all tracks and waypoints as line and point features. GPX metadata (name, description, time) is preserved as feature properties.

Supported input: .gpx

TopoJSON​

TopoJSON is a compact topology-aware format used in data visualization. It produces smaller files than GeoJSON for the same geographic data.

TopoJSON is converted to GeoJSON automatically during import. All arcs are resolved and the geometry is stored as standard GeoJSON in the project.

Supported input: .topojson

tip

GeoJSON, GPX, and TopoJSON layers all support the full Style Editor, including color-by-attribute, heatmaps, and 3D bar charts.
