Was playing in photoshop with the SpaceX logo and a timelapse of one of their launches. Hope they don't mind too much

Classification
![]() |
| Analysis of Great Salt Lake |
Three images of the Great Salt Lake taken by Landsat 5 in false color 5-4-3 configuration. Below the images show the classification. Remote sensing software is designed to recognize the spectral signature of certain land cover and, with a little help from the user, classify it into colors. It is a major part of remote sensing since it helps to quantify exactly what is happening in the imagery.
For example, the surface area and shoreline of the Great Salt Lake tends to vary greatly since it is located on a flat plain. Classification lets us count exactly how many more square miles of surface area of water, vegetation, and soil exist at certain water levels. Information like this is useful to the brine shrimp fishermen on the lake, the sailors who need to know when certain reefs are hazards, those concerned with the well-being of the millions of birds who stop at the lake while migrating, urban planners in the local communities, etc. etc. etc.

XKCD Hurricane map
Quick and dirty project I did for fun
I georeferenced and drew in the areas created by Randall Munroe at http://xkcd.com/1407/
I colorcoded the areas by year to give an idea of how recent these hurricanes were
He draws a pretty decent Mercator projection

Sand Blasted Paradise
Sand Blasted Canary Islands 01/10/2015 MODIS
Sand from the Sahara is sometimes blown all across the Atlantic in wind storms. Such storms and the rising warm and humid air can lift dust 5,000 meters or so above the Atlantic, blanketing hundreds of thousands of square miles of the eastern Atlantic Ocean with a dense cloud of Saharan sand, many times reaching as far as the Caribbean
This hot, oppressing dust and sand-laden wind is called the Calima by meteorologists and locals on the Canary Islands. It is particularly prevalent in winter. The Calima blows out of a high-pressure system over the Sahara and is drawn northwards ahead of a passing cold-front or depression north of the archipelago. It's fine yellowish-brown dust creeps through doors and windows. Outside visibility is often reduced to null.
This unnormal hot and humid Calima is a difficult part of life. The Canary people suffer from respiratory problems. On January 8, 2002, the international airport of Santa Cruz had to be closed because visibility dropped to less than 50 meters.
