Following sequestration and bitter budget wars in Washington NASA find itself in a difficult position. NASA has proposed a budget of $17.715 billion, down from $17.893B last year.…
In a previous post I talked about some of the remote sensing themes during the first half of the American Geophysical Union Fall meeting. Here I want to talk…
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…
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…
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.…
In this post I’ll take you through some simple functions in the freeware polarimetric SAR processing package, PolSARPro. The software is distributed by the European Space Agency (ESA)…
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…
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…
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…
