Generating an SVG from a set of shapefiles

The USGS provides detailed downloads of fire perimeters, with timestamped files that can be used to show the spread of a major fire over time.

Using the 2017 Thomas fire as an example, we'll process this data into a single SVG file with all the different perimeter measurements.

This index page contains links to a series of shapefiles of the fire boundary, each one with a timestamp:

This explains how to set up Vim on Ubuntu 18.04 on Windows Subsystem for Linux 2 (WSL2) in order to share the clipboard between Windows and Ubuntu.

Environments

Windows 10 Home
Ubuntu 18.04 on Windows Subsystem for Linux 2 (WSL2)

Steps

Build Vim with the clipboard option enabled
Set up VcXsrv Windows X Server

Problem: configure: error: could not find libxml2
Solution: sudo xcode-select -s /Library/Developer/CommandLineTools

Problem: configure: error: could not find geos-config within the current path. You may need to try re-running configure with a --with-geosconfig parameter
Solution: brew install geos

Problem: configure: error: could not find proj_api.h - you may need to specify the directory of a PROJ.4 installation using --with-projdir
Solution: brew install proj and then CFLAGS=-DACCEPT_USE_OF_DEPRECATED_PROJ_API_H pex install postgis

Problem: configure: error: gdal-config not found. Use --without-raster or try --with-gdalconfig=\

“Why isn’t the new year on the winter solstice?”

The answer, honestly, is that the Romans had no fucking idea how to run a calendar.

Like, seriously, people notice "OCTOber" and "DECEMber" and say, "hey, those mean 'eight' and 'ten', but they're the 10th and 12th months, what's up with that?".

If you've got a little more history, you'll know that July and August are named after Julius and Augustus Caesar, and think, "oh, they added those two months and bumped the rest of the months back."

Nope. The Romans were way, way worse at calendars than that.

	When I put the reference implementation onto the website I needed to
	put a software license on it.

	And I looked at all the licenses that were available, and there were a lot
	of them. And I decided that the one I liked the best was the MIT License,
	which was a notice that you would put on your source and it would say,
	"you're allowed to use this for any purpose you want, just leave the
	notice in the source and don't sue me."
