Automatically generating a legend for a choropleth layer in Leaflet

Some work I’ve been doing recently has involved putting together a webmap using the Leaflet library. I’ve been very impressed with how Leaflet works, and the range of plugins available for it. leaflet-choropleth is an extension for Leaflet that allows easy generation of choropleth maps in Leaflet. The docs for this module are pretty good, […]

Calculating Rayleigh Reflectance using Py6S

I found it recently while looking through back issues, and thought it deserved a wider audience, as it is still very relevant. I’ve made a few updates to the text, but it is mostly as published. […]

Cloud frequency map for Europe & update to cloud frequency web app
