The Long Swath

"The Landsat's natural-color imager scanned a swath of land 185-kilometers wide and 9,000 kilometers long (120 by 6,000 miles)—an unusual, unbroken distance considering 70 percent of Earth is covered with water. That flight path—depicted on the globe below—afforded us the chance to assemble 56 still images into a seamless, flyover view of what LDCM saw on April 19, 2013. Stretching from northern Russia to South Africa, the full mosaic from the Operational Land Imager can be viewed in this video."

Predicting Locations of Emergency & Damage During Disaster Using VGI Data

Predicting Locations of Emergency & Damage During Disaster Using VGI Data | GisZone | Scoop.it

The VGI data obtained from the Ushahidi-Haiti platform during the first 72 hours of Earthquake in Haiti can be used for predicting the locations of ‘Emergency and damaged areas’ using Ushahidi Reports in Port-au-Prince. Two rapid and very successful VGI deployments helped coordinate disaster response after a devastating magnitude 7 earthquake struck Haiti in January 2010.

In Praise of Paper Maps | Spatial Analysis

In Praise of Paper Maps | Spatial Analysis | GisZone | Scoop.it

Of the hundreds of maps I see each year, I would guess that less than 10% have been designed for printing. This to me is a great shame for a few reasons. Firstly, paper is just better in many circumstances. It is by far the most reliable means of storing navigation information: it doesn’t need batteries or an internet connection (you could say the maps are pre-cached) and you can drop it in a puddle and it will still work. It also offers a nice sized and efficient visual interface- street corners seem to be increasingly populated with those squinting into their phone. If you spot someone with an A-Z they tend to have a quick look at the map and then start looking around to get their bearings.

Social Impact through Satellite Remote Sensing - Visualizing Acute & Chronic Crises beyond the Visible Spectrum

Social Impact through Satellite Remote Sensing - Visualizing Acute & Chronic Crises beyond the Visible Spectrum | GisZone | Scoop.it

"For decades, satellite remote sensing has provided fundamental insights in countless physical science fields such as ecology, geosciences, atmospheric physics, and chemistry. However, as it relates to human and socioeconomic processes, satellite remote sensing is an incredibly powerful tool that is underutilized. Human behavior and socioeconomic parameters have been successfully studied via proxy through remote sensing of the physical environment by measuring the growth of city boundaries and transportation networks, crop health, soil moisture, and slum development from visible and multispectral imagery."

Seth Dixon's curator insight, December 15, 2012 12:41 PM

This article and the selected gallery is based on the free e-book "Earth as Art" which I've mentioned here before earlier.  This particular image is fantastic for teaching about geomorphology and river systems.  Students can 'see' the historical layers of a meandering stream winding it's way across the landscape.  Connecting the physical geography to human geography, analyzing the flood plains can help explain the land use and settlement patterns in this Mississippi Delta image.   

UPDATE: Here's another meandering stream image (Willamette River, Oregon) that shows the dynamism of fluvial processes quite nicely.

Nathan Chasse's curator insight, January 25, 2014 10:18 AM

This image tells the story of Akimiski Island's recovery after the last Ice Age, when it was covered with glaciers so large they sunk the island. The layered scarring on highlighted in the lower image was caused by waves as the island rebounded and rose along with the rising oceans as glaciers melted.

 

I wonder what forces are at work to raise the elevation of the island, possibly just decompression from the millions of pounds of pressure the island was under during the Ice Age.

Photogrammetric methods for recording archaeological structures at Zeviya Tivilki on the Upper Tigris, Turkey

Photogrammetric methods for recording archaeological structures at Zeviya Tivilki on the Upper Tigris, Turkey | GisZone | Scoop.it

The construction of large dams — and consequently the creation of extensive reservoirs — has obvious implications for the archaeological heritage and requires rapid archaeological intervention within the salvage projects set up in mitigation.

 

This is the case of the Ilisu Dam, which will affect the Upper Tigris region in a few years. The time allowed to excavate the sites in the construction area (Ökse et al. 2008) is even more limited, requiring us to carry out the investigations very rapidly.

 

As a result, we have developed a way of recording structures, using innovative methods of photogrammetry, to document quickly the plan and profiles of a single-storied building complex at the Iron Age settlement site of Zeviya Tivilki (Ökse et al. 2010).

 

The complex consists of foundations of rough stones set directly on the bedrock.
