Algorithm Talk: JSON-to-Code Compression
Daniel Dufour

This talk walks through a new algorithm for compressing JSON data, including GeoJSON. The JSON-to-Code algorithm compresses JSON data by converting it using recursive variable assignment into valid code that generates the JSON data. No prior coding experience required as the talk is at a high-level.

GeoRasterLayer for Leaflet: Truly Server-Free GeoTIFF Visualization
Daniel Dufour

GeoRaster Layer for Leaflet is a Leaflet plugin for visualizing GeoTIFFs on a web map. By directly reading the GeoTIFF file data and running all computations client-side in the browser, this library helps you easily put a GeoTIFF on a map without needing to run a server or write a lambda function. This talk will go over some short code examples and use cases. Familiarity with JavaScript is recommended but not required.
