Esri survey123 tool – rapid prototyping geographical citizen science tool

There are several applications that allow creating forms rapidly – such as Open Data Kit (ODK) or EpiCollect. Now, there is another offering from Esri, in the form of Survey123 app – which is explained in the video below.

Survey123 is integrated into ArcGIS Online, so you need an ArcGIS account to use it (you can have a short experiment if you register for a trial account, but for a longer project you’ll have to pay). The forms are configured in XForms, like ODK . The forms can be designed in Excel fairly quickly, and the desktop connection package make it easy to link to the Survey123 site, as well as testing forms.  I tried creating a form for local data collection, including recording a location and taking an image with the phone. It was fairly easy to create forms with textual, numerical, image and location information, and the software also supports the use of images to items in the form, so they can be illustrated visually. The desktop connector application also allow use to render the form, so they can be tested before they are uploaded to ArcGIS Online. Then it is possible to distribute the form to mobile devices and use them to collect the information.

The app works well offline, and it is possible to collect multiple forms and then upload them all together. While the application still showing rough edges in terms of interaction design, meaningful messages and bug clearing, it can be useful for developing prototypes and forms when the geographic aspect of the data collection is central. For example, during data collection the application supports both capturing the location from GPS and pointing on a map to the location where the data was collected. You can only use GPS when you are offline, as for now it doesn’t let you cache a map of a study area.

As might be expected, the advantage of Survey123 is coming once you’ve got the information and want to analyse it, since ArcGIS Online provide the tools for detailed GIS analysis, or you can link to it from a desktop GIS and analyse and visualise the information.

Luckily for us, Esri is a partner of the Extreme Citizen Science group and UCL also holds an institutional licence for ArcGIS Online, so we have access to these tools. However, through Esri conservation programme can also apply to have access to ArcGIS Online and use this tool.

OpenStreetMap in GIScience – Experiences, Research, and Applications

OSM in GIScience

A new book has just been published about OpenStreetMap and Geographic Information Science. The book, which was edited by Jamal Jokar Arsanjani, Alexander Zipf, Peter Mooney, Marco Helbich  is “OpenStreetMap in GISciene : Experiences, Research, and applications” contains 16 chapters on different aspects of OpenStreetMap in GIScience including 1) Data Management and Quality, 2) Social Context, 3) Network Modeling and Routing, and 4) Land Management and Urban Form.

I’ve contributed a preface to the book, titled “OpenStreetMap Studies and Volunteered Geographical Information” which, unlike the rest of the book, is accessible freely.
