Piedra del Águila Dam Reshapes the Limay River : Image of the Day

The best way to see the effects of those dammed humans… Really, it’s a cool way to view something that is useful and scary at the same time. Go to the link and then click on the [VIEW BOTH IMAGES] box below the aerials. You can then use a slider to compare the 1986 image to the 1998 one.

Where to Live to Avoid a Natural Disaster – Map – NYTimes.com

A friend of mine brought to my attention this nice little graphic from the New York Times online regarding where natural disasters tend to be, based upon historical data. Oddly, I noticed that where I live has a nice big (compared to others on this map),  juicy amber circle right over it. I can’t imagine what natural disaster they might be thinking about; even snow comes in manageable amounts here.

We occasionally get minor flooding and once in a blue moon major flooding (like last year with Tropical Storm Lee). Generally speaking, this area is temperate and lovely, with hot, muggy spells in the summer, but no natural disasters.

America Revealed | PBS

I just happened upon this series on PBS tonight – it is about all the stuff I am very much interested in. Patterns, nature – and tonight it happens to be about America’s “Food Factory”. Well, well! You can’t talk about that without showing those center pivot irrigation fields.

America produces so much more food than it really ought to be naturally producing, all due to artificially dragging water up out of the ground at rates and volumes so high that we’ll eventually be having wars over the stuff IMO. This is one point brought up; juxtapose this against feed-lot cattle and disappearing honeybees. It’s all quite disturbing.

One method used in the report is contrast between aerial photos of an identical areas in different years (one of my favorite things to do with aerials). It’s nice to make a point with patterns!

LiDAR in Archaeology

Years ago I went to a sales partner meeting at EROS in Sioux Falls SD. During a cool meeting there I got to see some applications of LiDAR in combination with aerial and satellite imagery.

Well – boy have things improved!

Pretty awesome quality! Just think of all the new old data we now could have access to!

Wind Map

I saw this really nifty real-time Wind Map today. I have nothing more to add to this other than to say it is utterly mesmerizing.

Jerry’s Map.

Beautiful clip on Jerry Gretzinger and the art of his maps. It is a whole new way to look at maps and the world.

DIVA-GIS | DIVA-GIS: free, simple & effective.

Just downloaded DIVA-GIS to try out. Seems small and relatively responsive; I’m unfamiliar with it but willing to try.  Let’s see how easy it is to work with!

Prehistoric Cartography

If you have any interest in maps and the history of mapping, this brief History of Cartography is pretty nice. It is geared toward the UK mapping universe, however,  and leaves out such cool things as stick maps of Micronesia and Inuit carved wood and antler maps.

Making maps in this abstract manner must have been difficult; were they made en route? Seems like the only way I could do it – with the terrain right there in front of me – but it also seems unlikely that they produced them in a kayak. What’s left? Amazing memories for topography and an ability to equate an abstract shape to a shoreline.

Google begins Amazon river “Street” View project

I ran across this bit o’ news this week while browsing around the BBC News. Looks like Google has another nifty thing up its sleeve.


I love this feature in Google Maps as it gives me a chance to see what places look like, and it allows me to “revisit” places I’ve already been. Using Street View is a lot like driving slowly down a road and still being able to look out all the windows of your vehicle. Very occasionally it offers a view of an unusual event in the vicinity of the Google Maps vehicle. While it would be extremely time-consuming to find these yourself – short of coincidence – GstreetSightings.com is a great shortcut to some of those odd happenings.
