DJI Zenmuse P1 camera quality test
If you zoom into JPEG images from the Zenmuse P1 camera they look “damaged” so I took a view from a stationary (on a table) Matrice300 in jpg and raw. Converted the raw simply to tiff, cropped both to look at a small area in focus:
The conclusion is capture RAW only on the P1 and batch convert later. Each raw is 86MB rather than 5-7 MB (which was suspiciously compressed for such a high resolution image) so you will need 10x the SD card space/disk space.
Fjalls tracker restarts!
The Fjalls tracker has restarted – perhaps uprighted itself – and data is now coming in daily again. The gap in the data shows that it coul not create accurate readings then – which could also be due to a problem with its base station..

There’s a lot of energy in a glacial outflow river!
The outflow river bed remained almost unchanged while it was monitored from Autumn 2012 to Summer 2013. However, sometime between July 2013 and July 2014, the flow became violent enough to move massive boulders, as these images from the bridge camera show.
River on 22 May 2013.
River on 1 August 2014.
Note the big boulder – about 1 m high – right of centre in the foreground of the earlier image, which has been swept out of shot a year or so later.
Amazing new time-lapse video from our “bridge-cam”
This was taken since last october (2012) and shows the incoming snow, melting etc.
