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 document contains some of the ffmpeg snippets I use most commonly, and typically in the context of converting research-related image data to video. It is not meant to be exhaustive.

The proposal you’re about to read is not just a proposal. We have a working implementation of almost everything we discussed here. We encourage you to checkout and build our branch: our fork, with the relevant branch selected. Building and using the implementation will give you a better understanding of what using it as a developer is like.
Our implementation ended up differing from the proposal on some minor points. As our last action item before making a PR, we’re writing documentation on what we did. While I loathe pointing to tests in lieu of documentation, they will be helpful until we complete writing docs: the unit tests.
This repo also contains a bundled version of npm that has a new command, asset. You can read the documentation for and goals of that comma
