A short code excerpt from this visualization I created for the longform article “Iouri Podladtchikov – You only fly once” by the Neue Zürcher Zeitung.
It's a very simple way to create an interactive animation based on video material. Hover over the image to go through the animation.
I used Final Cut Pro to crop and export the frames of a short video sequence, which I then stitched together into a single film strip using ImageMagick: convert folder-of-stills/* +append filmstrip.jpg

##How to get started contributing to a Humanitarian OpenStreetMap Team task
###Overview
OpenStreetMap (OSM) is an open-source map of the world that anyone can edit. But like any map, it's incomplete.
The Humanitarian OpenStreetMap Team (HOT) helps organize people to improve the OSM map for crisis areas, mostly so aid workers can find their way around and make decisions about undermapped places. The data in these crisis areas is often very poor, or completely non-existent. Therefore any contribution you make at all will be a vast improvement, and could materially help people who are on the ground right now, looking at this data as you edit it, and deciding where to go and who to help.
There are many HOT tasks active at once. As of August 2014, the highest-priority tasks are Gaza and areas affected by the West African Ebola outbreak.

I'm currently about to start a Geography degree at the University of [Redacted] at [Redacted] with a focus in GIS, and I've been finding that I have an interest in working with imagery. Obviously I should take Remote Sensing and other similar classes, but I'm the type of person who likes to self learn as well. So my question is this: What recommendations would you give to a student who is interested in working with imagery? Are there any self study paths that you could recommend?
I learned on my own and on the job, and there are a lot of important topics in GIS that I don’t know anything about, so I can’t give comprehensive advice. I haven’t arrived anywhere; I’m just ten minutes ahead in the convoy we’re both in. Take these recommendations critically.
Find interesting people. You’ll learn a lot more from a great professor (or mentor, or friend, or tutorial) outside your specialty than you will from someone boring who’s working on exactly what you’re interested in. Don’t get i
This script processes VIIRS Nighttime Lights 2012 GeoTIFFs from the Earth Observation Group at NOAA National Geophysical Data Center to prepare them for rendering in TileMill and uploading to MapBox Hosting.

This list of resources is all about acquring and processing aerial imagery. It's generally broken up in three ways: how to go about this in Photoshop/GIMP, using command-line tools, or in GIS software, depending what's most comfortable to you. Often these tools can be used in conjunction with each other.
