Remote Sensing at AGU (Part1))
The Fall Meeting of the American Geophysical Union is one of the largest annual gatherings of scientists. Some 22000 have descended on San Francisco to discuss topics from…
Landsat-8: how not to plan a mission (Part 2: the sensors)
In my previous post I described the difficult process that led to the launch of Landsat-8. Here I will comment on the two sensors, the Operational Land Imager…
Landsat-8: how not to plan a mission (Part 1: policy)
I was recently reading the 2012 article by James R. Irons and colleagues describing the Landsat-8 mission (or Landsat Data Continuity Mission, LDCM, as it was then called)¹.…
Freeware SAR processing (Part 1.)
One thing about working with synethic aperture radar (SAR) data is that regular image processing functions are often unsuitable. This is because most processes were design to deal…
A great visualization of InSAR data by the ESA – ups and downs at the East African Rift
InSAR (Interferometric Synthetic Aperture Radar) is one of the greatest remote sensing tools for everyone interested in crustal movements. The principle is simple: A satellite equipped with a…
XML, KML and ENVI 5.1
At the moment I am beta testing ENVI 5.1 and have been working with the new Region of Interest (ROI) tool. The new tool looks good with some…
What is the synthetic aperture in “Synthetic Aperture Radar” (SAR)?
Talking to a colleague recently about monitoring changes to the magrove forest of the Rufiji Delta in tanzania, he commented on the relative scarcity of satellite data over…
short announcement: Landsat 8 data available online
Thanks to a post from the mapbox colleagues I’ve found out that new Landsat 8 scenes are already available on EarthExplorer. The data is great!!!
short announcement: Earth Engine by Google
On the 9th of May Google introduced an astonishing new technology that makes the good old flickr function in Erdas Imagine quite useless. With the Earth Engine from…
The End of the Landsat 5 Era
If you have been working in the space remote sensing community for any length of time you have almost certainly crossed paths with Landsat 5. After 29 years…
