Phone app for fieldwork

With a mobile phone professional and citizen scientists can collect and analyse data anywhere in the world.

The full integration into a central and widely-accessible database makes this application particularly useful. For example, take the classic quadrant experiment in which schoolchildren set out a fixed area and count the number of species in that area. "If we have a database version, it allows them to compare between their school and another school or a set of schools in one country versus a set in another country, and the natural ability to use a phone rather than paper might be more attractive to school kids."

Mobile app sees science go global
BBC News 16 Sep 09;
A mobile phone application will help professional and "citizen" scientists collect and analyse data from "in the field", anywhere in the world.

The EpiCollect software collates data from certain mobiles - on topics such as disease spread or the occurrence of rare species - in a web-based database.

The data is statistically analysed and plotted on maps that are instantly available to those same phones.

The approach is outlined in the open-access journal PLoS ONE.

The software has been developed for so-called smartphones that run Google's Android open-source operating system.

Researchers can report back to the EpiCollect database with results from experiments they do in the field, and "citizen scientists" can send back photos or videos of certain species from their own backyards.

The phones' GPS system automatically logs users' locations, and the data is then plotted by location using Google Maps. Then anyone can access the database online, or from their phone.

Real-time results

There have been many research projects in the past that make use of phones' instant access and GPS functionality.

However, lead researcher on the project David Aanensen of Imperial College London said that the full integration into a central and widely-accessible database makes EpiCollect particularly useful.

"Many of the other tools that allow one to send data by mobile phone don't have an easy way for any of the researchers to look at any of the data in almost real-time," he told BBC News.

The team is already working to track the occurrence of chytridiomycosis, a fungal infection that is decimating the numbers of amphibians around the globe.

"We're investigating the use of the phones for the project; rather than researchers taking a GPS out into the field and recording their results on paper, we can get all of this data much more quickly - and it limits the amount of equipment they have to take out into the field," Mr Aanensen said.

He added that there is particular potential for using the approach with school projects. He cited the classic "quadrant" experiment in biology, in which schoolchildren set out a fixed area, for example in a park, and count the number of species in that area.

"If we have a database version, it allows them to compare between their school and another school or a set of schools in one country versus a set in another country, and the natural ability to use a phone rather than paper might be more attractive to school kids."

The team is now working to develop an iPhone-compatible version of the application. They are also as well as a website that, based on a given project's aims, automatically sets up a database and writes the computer code to be uploaded to phones.

"People who don't have experience setting up databases and setting up websites with maps will be able to come along and have their own project database and phone software provided," Mr Aanensen said.

"We want to just sit back and see the kind of exciting projects that people will be using this for."
