| Data Mime Type | Location Data | Geo Location Processing Description |
|---|---|---|
application/geo+json |
Point, LineString, MultiLineString, Polygon, MultiPolygon | GeoJSON Location Point coordinates are displyaed as clustered markers using leaflet.markercluster JavaScript library with custom marker cluster icons and config. Lines and polygons are added to the map and displayed via Leaflet 🌿 GeoJSON Layer. See our leafletMap.js for more info about that setup. |
application/json |
Objects that contain geo location property pairs ending with: latitude/longitude, lat/lng, or lat/lng |
Flat JSON data objects and arrays are processed by our custom GeoConverter to extract Location information and covert loaded dataset to GeoJSON for display on the map. |
text/csv |
CSV data with column names in the 1st header row and columns ending with: latitude/longitude, lat/lng, or lat/lng |
CSV data is parsed with d3-dsv JavaScript library and converted to flat JSON data array and then to GeoJSON with our GeoConverter to display locations on the map. |
application/xml or text/xml |
XML data with root node children that contain attributes ending with: latitude/longitude, lat/lng, or lat/lng |
XML data is parsed with fast-xml-parser to load it into JSON data objects array and then processed with our GeoConverter to display locations on the map. XML data support is very alpha and experimental at this point, and might be removed later. |
application/ vnd.code.notebook.stdout or text/plain |
Location data as string in CSV, XML, JSON or GeoJSON data format as described above |
Text data typically comes from display and console.log() instructions in vscode notebooks. We try to parse text as JSON with JSON.parse(), as CSV with d3-dsv.csvParse(), and as XML with fast-xml-parser. If those parse methods fail, or provided notebook cell text output contains no location data we can extract, we display text output in a custom scrollable text container with code pre-wrap for a quick copy/paste to other places. Otherwise, loaded data is converted to GeoJSON with our GeoConverter for locations display on the map. |
