The impact that freely available information has had on the learning community is truly profound, with tools like Wikipedia attracting huge audiences (over 365 million readers and growing). We can now access more data than ever – but what do we do with it all? If we want to take full advantage of all this information do we really have the tools we need? And how do we develop these tools in the future?

We are experiencing a massive explosion of online geospatial data from many new and unconventional sources from mobile devices to crowd-sourcing tools. Combined with newly released public sector information, we desperately need to integrate our tools for unlocking, exploiting, understanding and sharing these new data sets so that users can be provided with an accessible gateway to their display, mapping and spatial analysis.  Funded by JISC, GEMMA aims to produce a single workflow for the collection, mapping, preservation, sharing and visualisation of the geospatial datasets.

What does that mean in short? The ability to create a map without knowing anything about mapping. Simple as, for too long creating a map has been too complicated, there is now a vast amount of geographically tagged information available online, yet to map it you still have to have a considerable amount of computer related knowledge. Not any more, and we are not talking standard pin type maps, we will enable complex spatial mapping to be carried out at the click of mouse and a point at a file.

With applications as wide ranging as community participation, social simulation, economic analysis, urban modelling and beyond, the collection, visualisation, analysis and ultimately understanding of these datasets requires new software organised around a new series of workflows which integrate an array of tools.

Over the next 8 months we aim to produce a one stop shop for any user who wishes to take public sector, crowd-sourced, mobile and related online data with geospatial reference which enables them to display and overlay this information in non-proprietary or freely available mapping services on the web such as Google Maps or Open Street Map, building on several tools that CASA has developed such as, MapTube and SurveyMapper.

In typical CASA style, we will have frequent updates, beta releases and online apps. GEMMA will be integrated with various crowd sourced and open data sources complete with both iPhone and Android applications for viewing and collecting data in the field.

GEMMA kicks off March 1st, 2011, its time to make geo easy….

The term ‘mash-up’ refers to websites that weave data from different sources into new Web services. The key to a successful Web service is to gather and use large datasets and harness the scale of the Internet through what is known as network effects. This means that data sources are just as important as the software that ‘mashes’ them, and one of the most profound pieces of data that a user has at any one time is his or her location. In the past this was a somewhat fuzzy concept, perhaps as vague as a verbal reference to being in a particular shop or café or an actual street address. Recent events, however, have changed this. In the 1990s, President Bill Clinton’s policy decision to open up military GPS satellite technology for ‘dual-use’ (military and civilian) resulted in a whole new generation of location-aware devices.Around the same time, cartography and GIScience were also undergoing dramatic, Internet-induced changes.

Traditional, resource intensive processes and established organizations, in both the public and private sectors, were being challenged by new, lightweight methods. The upshot has been that map making, geospatial analysis and related activities are undergoing a process of profound change. New players have entered established markets and disrupted routes to knowledge and, as we have already seen with Web 2.0, newly empowered amateurs are part of these processes. Volunteers are quite literally grabbing a GPS unit and hitting the streets of their local town to help create crowdsourced datasets that are uploaded to both open source and proprietary databases.

The upshot is an evolving landscape which Tim O’Reilly, proponent of Web 2.0 and always ready with a handy moniker, has labelled Where 2.0. Others prefer the GeoWeb, Spatial Data Infrastructure, Location Infrastructure, or perhaps just location based services. Whatever one might call it, there are a number of reasons why its development should be of interest to those in higher and further education. Firstly, since a person’s location is such a profound unit of information and of such value to, for example, the process of targeting advertising, there has been considerable investment in Web 2.0-style services that make use of it. Understanding these developments may provide useful insights for how other forms of data might be used. Secondly, education, particularly research, is beginning to realize the huge potential of the data mash-up concept. As Government, too, begins to get involved, it is likely that education will be expected to take advantage of, and indeed come to relish, the new opportunities for working with data.

This TechWatch report describes the context for the changes that are taking place and explains why the education community needs to understand the issues around how to open up data, how to create mash-ups that do not compromise accuracy and quality and how to deal with issues such as privacy and working with commercial and non-profit third parties. It also shows how data mash-ups in education and research are part of an emerging, richer information environment with greater integration of mobile applications, sensor platforms, e-science, mixed reality, and semantic, machine-computable data and speculates on how this is likely to develop in the future.
