Urban Sprawl

Here are some incredible examples of urban sprawl as captured by the Landsat family of satellites since 1972. Here, for example, is Las Vegas.


Visible vs. Infrared Landsat 8

Here's a great example: the left image is based on the visible bands, right images uses two of the infrared bands on Landsat 8 - which one is more useful for fire fighters?

Climate Change Videos

So you have 50 minutes or so and want to show a video about climate change - here are some options:

Colors and Font (on maps)

Need advice? Try ColorBrewer 2.0 or TypeBrewer!




The Weather Bike

This is a fun project to do with students: mount a Kestrel gizmo on a bike and use to measure cool-air pooling or urban heat islands.




UAV Mapping of Himalayan Glaciers

Here's another UAV glacier-mapping example: Immerzeel et al. (2014). As they correctly point-out UAV imagery can be the missing link between point measurements and space-based sensors. The video below is an overview of their research (look for the UAV at about 4:00 minutes).

College Degrees and Majors

Ben Schmidt is doing some great interactive visualizations using D3 - here are two of them:
  1. How college majors relate to professions afterwards
  2. College majors changing over time

When in doubt - use science!

Excellent video demonstrating all kinds of things: earth rotation, Coriolis effect, and more using a Foucault pendulum. More about it at Wired Science.


AGO for Organization free for K-12

Looks like Esri finally woke-up and is making their ArcGIS Online for Organization subscriptions free for all K-12 schools as part of the ConnectED initiative. That's a good thing and a nice alternative to using Google Earth. Not sure how they will handle the user name and password administration for the students - from personal experience I can tell you that can be a big issue and inconvenience. Here's some more information:

Libre Map Project

I'm not really sure who and what they are, but Libre Map hosts an impressive array of GIS data for the United States, including detailed topographic maps and TIGER/Line files.

Climate Models

Why climate models are both wrong and valuable. Here's a (partial) transcript on Dot Earth.


Journey Through Time

Travel back in time through Switzerland with this awesome seamless mosaic (in space and time) of Swiss topographic map: Journey Through Time. Hello USGS - how about something like this for the USA?

Income vs. Cost of Living

These numbers are startling, but expected: how much are you really making when you consider your income vs. the cost of living?

Visualizing Politics in the U.S.

Here are two great visualization / infographics (I'm not really sure what to call them) of what goes on (or not) in the US Congress.

Climate Apps

Here are two compilations of apps related to climate and climate change:

NASA Climate Games

This is pretty fun: NASA Climate Kids has a bunch of fun and educational games around issues of climate change.

MAGIC Map Mash-Ups

The folks at UConn-MAGIC have created a series of great Google-based mash-ups showing historical data for Connecticut, for example:

SaTScan

SaTScan is free software program to analyze spatial, temporal, and space-time scan statistics. I don't really know what all that means, but maybe you do.

MS Excel

What can I say about MS Excel - I already posted how you can create GIS maps with MS Excel or how to create art with MS Excel - here's a useful add-on:
Have a look at John Nelson's clever Excel Hack Map - I have seen something similar from folks working with gridded climate data.

The National Climate Assessment

Well - this is about as official as it gets: the 2014 U.S. National Climate Assessment. The website is pretty fancy and a tad confusing to navigate, but you can download the report and its pieces from the Downloads page.


Street View, but different!

Point & Click Street View is the good old Google Street View, but with more mellow point-and-click navigation controls. Give it a try, I like it!

Tweeting the Obvious!

Mapping sunrise - this is further proof that most tweets are statements of the obvious and thus (largely) irrelevant: here we have an animated map of sunrise traveling around the Earth and tweets with the word 'sunrise' in them.

Very clever! Street Bump
