Ash Cloud apocalypse

Raphael Heath is planning his 2nd World GIS activity.

The technology of ArcGIS Online has moved on in the last year, and there is now the appearance of the GeoForm (of which more to come later)
This year, the focus is on an Ash Cloud apocalypse.

Between 16 to 20 November get your Geography students involved with a local disaster risk mapping activity. Are you ready for the Ash Cloud Apocalypse. Could you survive? Know your risks!

This is the launch video... more to come on this later in the year....

Using Google Earth to snoop on people

I was interested in an article that came through via Karl Donert
It describes how Google Earth is being used to check on people's general activity.

It can show cars parked in drives, home improvements, the appearance of outhouses etc. and then be used alongside other data from social networks e.g. postings from foreign holidays etc.
How much does this give away about your life?

OS maps as a basemap layer in ArcGIS Online

For those of you who are interested in developing your use of ArcGIS Online, a few new items of interest.
Some new base maps have now been added to ArcGIS Online
You'll need an institutional subscription to see them...

You can see that alongside Watercolour Stamen maps are also ORDNANCE SURVEY maps.

A further development that shows the power of this tool.

Also this week I have been exploring with GeoForms.
These are forms which can be created to connect with a particular feature service layer of the ArcGIS Online platform.... Fill in the form on your device of choice and the data is added to the map in the relevant place...

This is going to use a few apps.

Free GIS datasets

One issue with using GIS is finding the right data.

Robin Wilson has created a useful list of free datasets to browse through, along with a caveat about the quality of the data they contain.
This was an issue when we worked on training courses for ESRI about five years ago, and is still an issue, although organisations like English Nature and the ONS are now more open with their data.

Do you have your free Google Earth Pro version ?

I've had a free Google Earth pro license for a while now, but a few tweets and other messages today, and a post on Google Earth Blog reminded me that I hadn't necessarily mentioned it here, or recently, so here goes...

You'll need to get it from HERE, and also make sure that you have a license key, which you can request when installing'll also need to connect it to a specific e-mail address and choose a user name.

There are some extra features in the Pro version compared to the standard one... these used to cost hundreds of dollars to access, although I actually had a Pro version back in 2005-6 thanks to Dennis Reinhardt of Google... at the time I was working on the Earth: a Users Guide project, funded by the RGS-IBG, which became this blog.

If you have a previous version of Google Earth you'll need to delete or uninstall it first.

ArcGIS Online 3D Scene Viewer

As part of the recent December update to the software, ArcGIS Online now has a range of new features, which are summarised here.

One of them is the addition of catchment area calculations, and also downstream channel plots.. Tried this out for a local river and it worked well...

Also extra options for how maps are formatted for embedding on pages, and a new dark canvas basemap, which I like...
Here's a trial map of London

It's interesting timing given the withdrawal of the Google Earth API that one of the most interesting additions is the 3D Scene Viewer option.

Head here to find out more about it... one of my holiday plans is to get stuck into that and see what's possible...

ArcGIS Online

A new update to ArcGIS Online has been released, and the details are here.
Some very interesting new features described here.

Here's a 3D resource, for example which shows Volcanoes and Earthquakes.
Looking forward to getting stuck in to this...

Thought for the Day

Gotta keep it simple
Sending out a signal
Everyday is brutal
Now we're being watched by Google

Open Supermarket Data

Tracking twitter while having a writing day, and in came a tweet about some new data on supermarket locations, at the GeoLytix blog.
This hasn't previously been available as open data rather than commercially provided.

I downloaded it as an XLS and then converted it to CSV and split it into the different supermarket chains so that it can be viewed in ArcGIS Online - locations were using Postcodes for the time being, although other location options are available.
Here's the location of ALDI stories....

And here's a heatmap showing where ASDA stores are found in parts of the north of England...

Plenty of possible options now for exploring this data and looking at retail locations, demographics etc. plus supermarket location activities.

Thanks to @Geolytix for sharing the data

The Age of Megacities

Another rather fine ESRI StoryMap
I like the inset map feature top left...
