Day 17: A new tool

Played around with #rayshader to look at Mont Rainier (Washington).

A binned heatmap of alternative fuel sources in the USA.

A map of alternative fuel sources in the USA. Philadelphia example shown.

#30DayMapChallenge Day 16 - Cell
I made a binned heatmap of alternative fuel sources in the US (mostly electric charging stations but biodiesel, hydrogen + others are included). Darker colors indicate more in a given cell. See the full map here - shorturl.at/CSg3C

What was the weather like on your birthday? Now you can find out!

During the shutdown, I forced myself to stay agile in data science tech, like AWS, Google, and Open AI.

I made a notebook that gets weather for the day/location of your birth, using multiple NOAA sources.

Day 13. 10 min map.
Here are some town maps from Cities Skylines 2. It typically takes me around ten minutes to build out a new road network and connect it to existing infrastructure, zone, etc... Highly recommend if you're into city builder games! #30DayMapChallenge #CitiesSkylines

E.P.A. to Stop Collecting Emissions Data From Polluters The data, from thousands of coal-burning power plants, oil refineries, steel mills and other industrial facilities, is the country’s most comprehensive way to track greenhouse gases.

Breaking News: The EPA moved to stop requiring polluters to report their emissions of greenhouse gases. The proposal would end a key tool the government uses to track carbon dioxide, methane and other gases that are driving climate change.
