Massive geojson points file - memory issue

[Jul-Git]

Hello everyone,

I am trying to load a huge (in my point of view) geojson point file (over 150000 points with descriptions). On some PC, with not enough RAM, it is not loading at all.
Is there a workaround to load such massive dataset into TerriaMap ?

Hi @Jul-Git

We support mapbox vector tiles. So you can use something like tippecanoe to tile and generalise your geojson points file/

They have an example with large point dataset here - https://github.com/mapbox/tippecanoe#large-point-dataset-gps-bus-locations-for-visualization-at-all-zoom-levels

You can then add a MapboxVectorTileCatalogItem like so:

{
      "name": "Points",
      "type": "mvt",
      "url": "https://some-domain/some-path/{z}/{x}/{y}.vector.pbf",
      "layer": "layer-name"
      ...
},

See MapboxVectorTileCatalogItem docs
