geo

sublimated renders .geojson files as interactive maps. push via git, view the rendered map on the web.

• maps are rendered client-side using MapLibre GL JS

• geo metadata (format, bbox, feature count) is extracted server-side on push and stored as item attributes

• the raw GeoJSON is fetched from CAS and rendered onto the map

• supports points, lines, polygons, and mixed FeatureCollections

demos

one file per geometry type — push them to see them rendered:

• points — world cities as point features

• lines — routes and paths as LineStrings

• polygons — country/region boundaries as Polygons

• mixed — FeatureCollection with points, lines, and polygons together

• single — a single Feature (not wrapped in FeatureCollection)

how it works

1. push a .geojson file via git (or upload via API)

2. sublimated detects the geo format and extracts metadata (bounding box, feature count, geometry types)

3. metadata is stored as item attributes: geo_format, geo_bbox, geo_feature_count

4. when you view the file, MapLibre GL JS loads from CDN and renders the data on a map

5. the map auto-fits to the bounding box of the data

6. polygons get a semi-transparent fill, lines get a colored stroke, points get circles

supported formats

phase 1 (now): .geojson files served directly from CAS

future phases:

• geoparquet (.parquet with geo metadata) — needs features API endpoint

• shapefiles, KML, CSV with lat/lon columns — needs server-side conversion
