The Calbuco volcano in southern Chile has erupted twice in the space of a few hours - having lain dormant for decades.

Footage from the area shows a huge column of lava and ash being sent several kilometres into the air.

The authorities have declared a red alert and evacuated more than 4,000 people within a 20km (12 mile) radius.

The Calbuco volcano is one of the most active in Chile, but its eruption took officials in the area by surprise.

Alejandro Verges, an emergency director for the region, said Calbuco had not been under any special form of observation.

Lidar Massachusetts

I have created several more Lidar maps but this time they are all based in Massachusetts. The Lidar data itself was not as high resolution as the Utah data since they are a few years older but they are fun to look at. What a difference a few years make as newer sensors and methods are used. My favorites are probably the Boston Harbor Islands and Provincetown maps. Enjoy!

Lidar Salt Lake City

Introducing downtown Salt Lake City through the eyes of Lidar. This map

was made from public Lidar data from the AGRC. It is based off of a DSM 

(Digital Surface Model) that has been processed with a hillshade. It reminds 

me of a classic plat map or some of those city word art maps. Salt Lake's

unique geography really helps bring out this feeling. This will hopefully be

the first of many as I delve into other cities datasets and try to make similar ones. 

Please let me know if there are any cities in particular that you would like me to look 

at first. Also, if you are interested in a nice print version just send me a message or 

leave a comment below.

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
