Merry Gridmas!

 Gridviz is a Javascript library for visualizing gridded (raster) data. They created a Christmas themed map showing land use with holiday emojis. 

Also if you visit the Gridmas page you can watch the snow fall over Europe. You can pan and zoom around, however if you try to go elsewhere in the world you’ll see that the data has its limits.

There are a few options at the bottom of the page, allowing you to change the view to a population map showing how many Christmas elves live in each grid cell using your emoji of choice.

So, have yourself a merry gridmas!
