Are you a regular user of Landsat 7 data but are tired of the scan line errors?
Perhaps you are frustrated by the inability to collect Landsat data within the time frame you need?
Or maybe you are working on a regional land-use model that needs low-cost and recent imagery over an entire country?
Whatever your reason is for needing low-cost, medium resolution imagery, DEIMOS-1 is the solution. With a price point below 30-cents per square kilometer (sq km), DEIMOS-1 offers three-band (i.e. green, red and near-infrared) 22-meter resolution as both a new collection and from a growing archive.

A variety of Pléiades 1A products are available from both a growing archive and as a new collection, including 50-centimeter (cm) pansharpened imagery and 50-cm panchromatic – 2-meter (m) 4-band multispectral bundles. We are happy to discuss the technical specifications, pricing and tasking options available … Read more
- In my continued look at the renewable energy world, I turn my attention to advancements in solar technologies. Of all the articles I review each day, solar energy is far and away the most common topic. As such, I will offer a high level summary of as many of the best articles I found recently and then provide links to each so you can find out more. Multiple efficiency records were set recently: (1) Alta Devices set the record for cells made of gallium arsenide (GaAs) at 28.3% by including semiconductor materials which created luminescence; (2) Heliatek has created an
Over the last decade, there has been much uproar over the use of plastic bags at grocery and retail stores. Often referred to as single-use bags, they are known to take an extraordinarily long time to break down in landfills. There isn’t a commonly agreed upon length of time, but estimates vary between 500 and 1,000 years. To make these estimates, scientists use respirometry tests. The test gives newspapers a life-cycle of 2-5 months, whereas a banana peel takes a few days. When the test is applied to traditional plastic bags you find at grocery stores, there is no decomposition … Read more
Researchers from universities all over the world got together to study the impacts of school redistricting. They used GIS to make the most logical, and fair, districts which ensure students are given the best opportunity for education, as well as to have the minimum travel time from home to school. School redistricting is often done in response to overcrowding, decline in enrollments as well as considerations for schools that are planned to be opened or closed. The biggest dilemma in school redistricting is balancing the need for overall efficiency vis-à-vis individual convenience. There is also an element of geography in … Read more
The Dish near Palo Alto, California blasts us across the Atlantic Ocean for this edition of Small World. And we land in Albi, France, located in the Midi-Pyrenees region of France. It is the largest metropolitan region of France by area, larger than the Netherlands or Denmark. The region was named without regard to historical context, and solely on its geography. Midi means southern France, and Pyrenees refers to the mountain range on its southern border.
The first human settlement in Albi was during the Bronze Age, and remains that have been unearthed indicate that it was a Roman settlement … Read more
