IEOS2017 and Copernicus Info Session - 2nd and 3rd November

Two great events coming up in the EO field, the annual Irish Earth Observation Symposium and the first Irish Copernicus Info Session. Maynooth hosted the IEOS in 2014 and it was a great success with over 150 people attending over both days. This year we've extended the second day to a full day and  are pushing for an even bigger attendance, we already have more than 150 registered with 3 weeks still to go. The Copernicus team are joining us on the second day to demonstrate the massive potential that their services and datasets promise for GI professionals and the wider user community. We will have exhibitors, keynote speakers from ESA, GEOS and the minister confirmed to open the event.

Abstract deadline for the IEOS is this Friday, 13th October. If you are interested in satellite, airborne, drone, terrestrial - multispectral, hyperspectral, SAR, thermal, orthoimagery - image classification, 3D models, monitoring  then this event is for you.

It is free to attend so get registering!

Underwater Laser Scanning

Readers of this blog might remember my interest in the many excellent shipwreck 3D models downloadable from the GSI/MI/INFOMAR online dataviewers. I discovered a related article recently on very high resolution underwater laser scanning of wrecks being carried out with the help of the university of Southampton. Image of an old galley scanned as part of the project below..

Wow - look at that detail, and look at how well preserved it is despite being exposed! They say this model was created through photogrammetric methods - which is interesting in itself and one of the first underwater applications that I have come across, if you discount some of our bathymetry tests using the UAVs imagery.

Thanks to LiDARNEWS for tip off on the full story

Largest Full-Disc Video of Earth

Some fantastic images from a Russian weather satellite in one week combined into a vid  - fascinating to watch the shadow coming around every day, plus the sun reflected in a whole ocean.

Ploughing / Swimming 2017

The first tent I came across at Ploughing 2017 was the met.ie tent, sitting in the middle of a small lake. Very heavy rainfall on the second day for my turn at the SCSI stall.

Video here of my talk.

Oysters and Guinness

An Irish delicacy - well recommended.

I grew up about 100 metres from the Broadmeadow estuary in Malahide, and I can still remember the remnants of a fishing village before the town expanded in the 80's and became the wealthy coastal village it is today with bustling marina, upgraded international cricket ground and other new additions.

Be not sparing, leave off swearing,
Buy my herring, buy my herring, buy my herring,
Fresh from Malahide, better ne'er was try'd.
Come eat 'em with pure fresh butter and mustard,
Their bellies are soft and white as custard,
Come, sixpence a dozen to get me some bread,
Or like my own herrings I too shall be dead.

Supposedly by Dean Swift, 1746

The estuary is a beautiful feature, with a number of wildlife sanctuaries around it. I never set foot in it until I was in my 20's when I rented a small sailboat for an hour. No-one in Malahide does, it is just for watersports - if you want to swim, you go to the beach on the far side of town or else a bit further afield to Portmarnock. I never understood why and still don't, even on the hottest of days.

But I was looking at an old map recently and I see that the estuary was once used for far more than watersports - there were a number of Oyster beds. I couldn't find the map last night - I was almost sure it was the 6" or 25" mapping on OSi map viewer but it does not have the map I am looking for. I did find an interesting page from the historical society discussing the effect the railway had on the oyster fisheries - the owner "was very favourably circumstanced till the railway was made, but the mud is since increasing." This page helped me track down the map in question - it was the Rocque map of 1760 which I cannot find in digital form online.

What had reminded me of this map was an interesting usecase of Landsat 8 imagery for identifying optimum sites for oyster beds in Maine - using Landsat 8 to calculate thermal properties of an area, turbidity and chlorophyll a, they could deduce where they could grow rapidly.

It would be an interesting study to see how the Broadmeadow estuary fares now - almost 200 hundred years since the railway was built - because the Guinness in Malahide is still great.

wifi mapping of building interiors using drones

This is extremely impressive - two drones operating in tandem on the exterior of a structure and mapping the interior remotely using wifi. Reference data and resulting 3D map below..
