Map visualization of datacenters and drought occurrences in Western USA on June 22, 2021.

Research by Gauthier Roussilhe. Technical cartography work by B. Keller and F. Manca.

Pre-requisites:

• Python 3.8+
• C libraries (install via apt, brew, or another package manager for your system):
  • geos
  • proj
  • spatialindex

Then run the install script:

scripts/install

First, initialize datasets:

scripts/initdata

Generate the map (output in out/):

scripts/main

Problem: during scripts/install, one of these errors shows up:

  lib/cartopy/trace.cpp:633:10: fatal error: 'geos_c.h' file not found
  #include "geos_c.h"
           ^~~~~~~~~~
  1 error generated.
  error: command '/usr/bin/clang' failed with exit code 1

  lib/cartopy/trace.cpp:634:10: fatal error: 'proj_api.h' file not found
  #include "proj_api.h"
           ^~~~~~~~~~~~
  1 error generated.
  error: command '/usr/bin/clang' failed with exit code 1

Solution:

• brew install geos
• brew install proj@7.
• Add export CPPFLAGS="$CPPFLAGS -I/usr/local/opt/proj/include" to your bash profile (e.g. to ~/.zshrc).
• Restart your shell.
• Ensure pkg-config --cflags proj shows something like -I/usr/local/Cellar/proj@7/7.2.1/include.
• Retry.

• Datacenter data from datacenters.com.
• Drought data from Drought Monitor.
