We have had the capability to create story maps (multimedia-rich, live web maps) for a few years now, and we have also had the capability to collect data via crowdsourcing and citizen science methods using a variety of methods. But now the capability exists for both to be used at the same time. One way is with the new crowdsourcing story map app from Esri. To get familiar with this new app, read this explanation and explore a new crowdsourced story map that, after selecting “+ Participate”, prompts you for your location, photograph, and a sentence or two about attending, in this case, the Esri User Conference. If you did not attend, examining the application will give you a good sense for what this new app can do.
We have also written about location privacy concerns in the book that Jill Clark and I wrote about GIS and public domain data. The story Map Crowdsource app is different from the other Story Maps apps in that it enables people to post pictures and information onto your map without logging in to your ArcGIS Online organization. Thus, the author does not have complete control over what content appears in a Crowdsource story. Furthermore, the contributor’s current location, such as their current street address or locations they have visited, can be exposed in a Crowdsource app and appear with their post in these maps as a point location and as text. This may be fine if your map is collecting contributions about water quality, invasive plant species, or interesting places to visit in a city, where these location are public places. But it may not be desirable for other subject matter or scenarios, especially if your students may be posting information from or about their own residence.
Thus, it is up to you as the author of a Story Map Crowdsource app to ensure that your application complies with the privacy and data collection policies and standards of your organization, your community, and your intended audience. You might wish to set up a limited pilot or internal test of any Story Map Crowdsource project before deploying and promoting it publicly in order to review if it meets those requirements. And for you as a user of these maps, make sure that you are aware that you are potentially exposing the location of your residence or workplace, and make adjustments accordingly (generalizing your location to somewhere else in your city, for example) if exposing these locations are of concern to you).
Thus, the new crowdsource story map app is an excellent example of both citizen science and location privacy.
