#Technologyweek on Twitter

Make sure to take a look at some of the twitter posts in the sidebar - I'm giving a few updates for #Technologyweek for #YearofGeography.

Story Telling From Space

I came across an excellent intro on satellite imagery on twitter during the week -  but what really caught my attention was some of the supports dedicated to journalists, like 'Satellite Journalism - the big picture' - a paper showcasing loads of examples of EU data used in investigations around the world, this has so many examples from a quick skim I gave it this morning that it is a must read.

Another interesting resource - Earth Rise Media is an EO company that aims to help journalists with 'story telling from space'. tons of good stuff in these different links - need time to go through it properly and I want to have a proper read of the satellite journalism one.

Free (LiDAR) Datsets

I came across a great resource recently and have directed the MSc GIS/RS students to it for their next assignment. OpenTopography is a huge repository of freely available topographic data (raster and vector) but of particular interest to the GIS/RS students is the point cloud data that they are using for their LiDAR assignment. 

I counted 271 aerial LiDAR datasets, 8 terrestrial laser scanner datasets and 4 photogrammetrically-derived point clouds. I was impressed not only by the volume but also the variety, with point clouds of everything ranging from volcanoes to landslides to urban centres. It is a simple drag and drop selection and download interface and you don't even need to register for the smaller files. It will also provide partial processing for you in the download options! Data is largely concentrated in USA but I spotted data for New Zealand, Spain and other locations.

My only complaint so far is that when you are selecting data for one of the change detection studies (very helpfully flagged as such in the listing) you do not know where in the test site the change occurred - but the dataset is too large to download it all and find out, so you are kind of snookered! Note: I googled for a nice image to show snookered but there was none, what's up with that?

GIS in Schools

Some big news for geography (and geo in general) just before Christmas. ESRI - the largest supplier of GIS software in the world (and founded by the man with the excellent name - Jack Dangermond) has recently announced nearly half a billion euro worth of GIS and mapping software for primary and secondary schools around the country. Almost a million students, in 4,000 schools will all have free access to AGOL. This all feeds into the digital strategy action plan - launched in June by Minister Bruton and will be a huge benefit to students. There was one map on the wall of the geography class in my school - that was it.

Its a shame with this type of investment going into the schools that Geography is not still a compulsory subject at junior level.

Congrats to all involved in the initiative - I have heard a few familiar names come up in conversation.
