The first map of the month for Teagasc in 2019 is for once turning clouds to our advantage. It looks at the number of cloudy pixels in the 2018 MODIS archive compared with the decadal average and to no ones surprise we had 10% fewer cloudy observations in 2018.

The Copernicus Sentinel-2 mission takes us over the island of South Georgia. Linked with the South Sandwich Islands to form a British Overseas Territory, this southern Atlantic island is a haven for a vast array of wildlife.
Around five million seals call the islands home, as well as 65 million birds of 30 different species. Migrating whales and various fish species populate the surrounding waters and there is a large penguin population.
In 2012 the UK Government designated South Georgia as one of the world’s largest sustainable use Marine Protected Areas. Significant investment has also been made in fisheries management and scientific research, as well as targeted conservation efforts to help protect the albatross. South Georgia is home to the Wandering Albatross – the largest flying bird species in the world.

Whilst researching some old soil data from our AFT soil survey archive I came across this photograph of Paradise Hill on the limerick/cork border taken in 1964 (the hill is in the middle ground, the Galtees in the background). I thought I’d see how it looks today and a quick Google street view drive by pretty well recreates the image.
Obviously the big change is the forestry on Paradise hill and on the flanks of the Galtees to the right. But a couple of more subtle points are worth noting. The field structure seems pretty much the same but the hedgerows seem much taller and fuller today than they were in ’64.
The 64 image was taken by J. P. O’Callaghan and you can see the Google data directly here: https://goo.gl/maps/FJscHZ9G3o62
Teagasc’s last map of the month for 2018 uses accumulated NDVI to look at the total impact on production of this years drought.

At the coding workshop run by Jesko Zimmermann at this years IEOS I went through a few online resources for finding imagery but more importantly for finding pre-baked EO products. A couple of people asked me to post them so here they are:

I’d like to thank all 100+ attendees at the Irish Earth Observation Symposium in Teagasc Ashtown last week, you made it all a great success with fascinating talks and posters.
I’d like to personally thank the local organizing committee for there help and especially Jesko Zimmermann for doing a great job with the Friday coding workshop.
See you all next year- ICHEC has agreed to host, so watch this space!
Team Teagasc just won first place in the Farming by Satellite Competition!!!!
