Abstract
How graphics tech (WebGL, texture formats and shaders) and multispectral imagery (GeoTIFFs with multiple bands or samples) are a perfect match. An overview on the work done in Leaflet.TileLayer.GL (and its OpenLayers port) to let web applications consume raw GeoTIFF data (including multiple bands and pixel formats), in order to perform raster algebra in the web browser itself (that’s called “edge computing” for buzzword-loving people).
