As far as accessible platforms for working with GIS, mobile apps are quickly gaining popularity. For this lab, Survey 123 was used; an ESRI application that allow the user to create a survey, collect data (through mobile devices), and publish that data as web apps, maps, and other platforms. An ESRI Online lesson was used to familiarize the students with how this platform is used (see Methods section) in the scenario that data was being collected for an emergency preparedness survey.
Methods
The first step to collecting survey data is to create the survey. To do this, go to the Survey 123 website and sign in with either an Enterprise account or an ESRI account. Once signed in, click the "Create New Survey" button (figure 1).

To do this, click Add Questions from the Design window (figure 4). There are many different question types to choose from.

From there, adjust symbols (red circle in Figure 10), configure pop-ups, and select theme for a web app to share this data with an organization or the ESRI community (figures 11 and 12).

Results

There were some trends that ensued when analyzing this fake data (I completed 5 surveys with various answers). Some of which include:
- All who took the survey were college aged students.
- Most who took the survey lived in single family homes.
- Most who took the survey did not secure their T.V., computer, or bookshelves.
- 60% of those who took the survey had an axe, some batteries, and/or a First-aid kit.
Discussion
This technology can be extremely useful as smartphones are becoming more accessible. As seen in the Methods section of this lab, it was fairly easy to create and publish this survey- collecting the data was even easier. In a real scenario, the surveyor would just sit back and let end-users input their answers, allowing the app to collect the data. The interoperability between Survey 123 and ArcGIS online makes visualizing the data through a Web App streamline.
Some drawbacks of this technology are that end-users who don't have the app installed on their mobile device might not want to install it and this can affect the data. Potential end-users might not have access to a mobile device and this would also affect the data. These drawbacks are important to consider when disseminating the survey and the surveyor should ensure that their is an online version explicitly available to those who apply to one or both of the concerns mentioned previously.
Overall, I think this is a really cool way to collect geospatial data in a high-quality and aesthetically pleasing platform.
