OS Terrain 50
OS announced this weekend the availability of OS Terrain 50 (T50), a maintained 50m DEM of the UK. This is great news as 50m provides an incredibly useful spatial resolution for a variety of tasks....

New dawn for "geoservices"
For want of a better name (new cartography, neogeography, geoservices or maybe geomatics!!), Science has a nice article on the emergent importance of geo in the global economy and the subsequent requirement for suitably qualified employees, noting a ~35% predicted growth in workers in the US by 2020. That's pretty big! Worth also reading the linked Oxera report for Google on Geoservices.
Bright future ahead people!

OpenShift have a good post of using QGIS for loading spatial data and then does some spatial processing using Python and GDAL for import. Its a good primer and forms part of a series on open source spatial - part 1 looked at spatial data

Proprietary data silos
.....and the moral of the story is.....
.....don't lock your data away in proprietary silos. The quotation at the end is fabulous: " A person seeking public records should expect to pay the price for copying the records, but not the price for a public entity’s mistake in purchasing inefficient software."

OS Past and Present
Nice pair of contrasting videos about OS - the first a modern promo video from the OS itself which is very glossy but actually tells you very little about the organisation and the second from Pathe news in the 1950s which is cringingly dated, such as "It used to take two men a whole year to do the map making mathematics that these adding machines and electronic computers can do in an afternoon with a girl to help!" However it does show you the full map making process in 3 minutes - quite a feat!

Nice post from James Fee on software agnosticism..... and yes, we all too regularly build an ArcGIS script to find it no longer works in a new version or hasn't been updated by a third party. And yes, the answer is don't use them!!! However as I am also doing (some work with Niels Anders), move to Python and do you geospatial processing there, then call from within ArcGIS. You even have Portable Python so no excuse for being tied to a workstation.

GIS as a profession?
A thought provoking article from David DiBiase at Esri Inc on Strengthening the GIS Profession. It outlines some of the history of the profession, the growing importance to the economy, primary traits of a "profession" and whether GIS meets them. A useful read for all aspiring and current GIS professionals.

Google Maps History and Applications
Nice catch from Very Spatial on the recent Google Maps press announcement. Well worth watching at least the first half which gives a great summary of the history of Google Earth (from SGI and Keyhole) and some of the applications of maps. The StreetView Trekker at around 35:00 is really rather cool - have a StreetView device on your back and weighting only ~40lbs. I guess they don't sell them!!

FOSS - 2012, alt update
A nice list of FOSS software, with a particular focus upon geoscience and academia. Everyone will find something new and useful both in the main list and also the comments (good pickup from GoGeo).
Some of the new picks for me included Shotwell (wish there was still a Windows port) and SQL Manager (a Firefox extension). The latter is particularly useful where you want to store structured data in a database that you can use SQL queries on. And the following two catches are quite interesting: tutorial on creating maps in R and Natural Earth data.

Geotagging - always a good idea?
Nice pick-up from The Guardian..... geotagging photos and uploading is a popular pastime for some, however it can have unintended consequences as the US Army points out.
Warren cited a real-world example from 2007. When a new fleet of helicopters arrived with an aviation unit at a base in Iraq, some Soldiers took pictures on the flightline, he said. From the photos that were uploaded to the Internet, the enemy was able to determine the exact location of the helicopters inside the compound and conduct a mortar attack, destroying four of the AH-64 Apaches.
Ouch! There must have been a big sigh when that happened. Might as well have stood there waving a flag saying shoot me.

Google adds postcode extents
Nice pick-up by The Guardian..... Google Maps now defines postcode extent when you query the postcode itself: for example. I'm assuming this is CodePoint, as per my previous blog.

New release: GDAL/OGR
A new year and a new release of GDAL/OGR (1.9). It's been a while since I last covered this, but there continue to be significant improvements with the big news being the support for ESRI File Geodatabases and Google Fusion tables (see James Fee's blog). However CounchDB, Idrisi, GRASS, ARCGEN are all worthy additions. Keep it in the toolbox.... because most of us do, and that includes ESRI.

Beidou is here
Well just about.... Beidou is the Chinese GPS equivalent and is now "operational". Well its got 10 operational satellites and these will provide coverage for China and near-surrounds. Expect global coverage by 2020. Whilst perhaps uptake won't be quick, it is designed to be inter-operable and expect to see handsets starting to take advantage of US, Russian, European and Chinese satellites for positioning. An exciting marketplace at the moment....

More open data....
This is nothing but great news..... more open data! There is some genuinely useful stuff here: Met Office Public Weather Service, train/bus real time running and Land Registry. All valuable/useful stuff in and of itself that should already be public. In addition to last weeks criminal court sentencing records, there will also be personal health records. These will (anonymously) tell a very detailed story about the UK and provide invaluable data for further analysis by academics and companies.

How cool is this ball camera?? Love the application.... our Leica laser scanner grabs similar imagery and splices them together but this is so elegant and you get a whole sphere of imagery. The alternative would be to fish-eye images but not as easy to do. Great!

STOP PRESS: ArcGIS Virtualised
Tech support at Kingston seem to have successfully virtualised ArcGIS 10 SP1. This has been a (very) troublesome app for sometime and particularly all the old ugly UNIX code that sits behind toolbox. Just loading Toolbox would cause the app to stall for 1 hour whilst it streamed the underlying code across the network. This has been reduced to about 1 minute which is then cached. Hopefully this will be rolled out on a trial basis side-by-side the installed app for student testing.

Following on from my earlier post Alasdair Rae at Sheffield Uni has now updated to include earlier years. From the horses mouth (so to speak):
"Just click on an area for a pop up with chart showing IMD ranks from previous years. I've included the chart (a bit of code which has been difficult to figure out!), the numbers and the rank change between 2004 and 2010. Hopefully this is of interest."
Get it here. Very useful stuff.

I original thought this an April Fool when I saw it reported over at Very Spatial in that the original report snuck in on April Fools' Day, however the original product release was December last year..... so, what the heck. Anyway, the general topic of GNSS supporting mutiple networks is clearly on its way, but perhaps sooner than some thought.

Indices of Multiple Deprivation
The 2011 Indices of Multiple Deprivation have recently been published. The Guardian Datablog has a good summary of the data; brief LA level summary data is available for download, but you'll have to hunt around the DCLG website (which is linked) for the actual data itself and also request the super output areas from the ONS to make any sense of it (or go to UKBORDERS for the 2001 borders). However the hard work has already been done in that Alasdair Rae up at Sheffield has already put the whole of the UK data in to Fusion Tables and linked it to Google Maps here. Very good stuff.... the next stage is to add in previous years!
