State of play on gridded data web visualisation

This page lists of some existing tools and techniques for inspiration, as examples (good or not so good), on interactive visualisation of gridded statistics.

• http://bl.ocks.org/letmaik/e71eae5b3ae9e09f8aeb288c3b95230b - Starting point for using a canvas grid with Leaflet
• https://dancooksonresearch.carto.com/u/dancookson/viz/49ca276c-adf9-454a-8f64-0ccf0e46eed0/embed_map - Based on raster data - no client side rendering. Mechanisms to allow mouse over tooltips with values (based on UTF grids approach certainly).
• UTF grids:

  • https://github.com/mapbox/utfgrid-spec/blob/master/1.3/utfgrid.md
  • https://github.com/mapbox/utfgrid-spec
• http://www.dwtkns.com/density/# Based on a static image series: http://www.dwtkns.com/density/m.png
• https://deck.gl/ and https://kepler.gl/
• http://blog.mastermaps.com/2015/11/mapping-grid-based-statistics-with.html Code is there: https://github.com/GeoForum/veiledning08
• https://github.com/Viglino/insee-map - Based on OL. No tiling. Generation of multi-resolution pyramid on client-side. Several stat variables. Rendering on canvas (?).
• https://ihcantabria.github.io/Leaflet.CanvasLayer.Field/example_VectorFieldAnim_With_ScalarField.html - Select 'derived magnitude' to see - how an ASCII file is rendered onto the canvas. Code here: https://github.com/IHCantabria/Leaflet.CanvasLayer.Field/blob/master/src/ScalarField.js
• https://www.pixijs.com/ + zoomable https://www.npmjs.com/package/pixi-viewport
• https://threejs.org/
• cogeo, with geotiffjs.
• flatgeobuf
