Mobiles & Field Data Collection
September 9th, 2011 by Matt Sheehan
A key challenge of building the demo was finding a suitable mobile application tool set. Initially we discussed using a combination of SimpleGeo with a mapping API. But MapQuest came to the rescue with their new Flash mobile tool set. Not only do they provide routing and traffic data, but local search, and a range of other functionality all easily integrated with the map.
Mobile Worker Data Collection Application – Opening Screen
The opening screen in the application shows the base functionality. Each view or tool is listed as a selectable image. At any point a user can open the map to see their current location. This changes as the user moves. As we will discuss, the map is also utilised by other tools in the application.

Mobile Worker Data Collection Application – Directions Screen
Let’s imagine a potential scenario. A field worker starts each day by opening a mobile application such as the one we are describing here. They want to start by seeing the days calls and an optimised route to these calls, mapped out for them. In Figure 2 we show a single source and destination mapped. MapQuest also allow for multiple source-destinations to be entered and displayed. At any point in the day the user can open this tool and see on the map the location of their next call.

Mobile Worker Data Collection Application – Check-In Screen
Next, the worker arrives at the first call and wishes to check-in. Figure 3 shows the check-in screen. There are two options shown. First a check-in by venue; so a field technician about to fix the air conditioning in a specific 7-11, for example. In the demo the user would type in the address, this could just as easily be a selection from a list of venues nearby. The second option is a check-in by current location or lat/long. Maybe a surveyor wishing to record, or check-in at a particular point. The check-in process would send name, id, location and time to the company server. A check-out would similarly record similar data centrally.

Mobile Worker Data Collection Application – Local Search Screen
At any point in the day a field worker might wish to do a local search. A search for venues, points of interest, maybe people within a certain distance of a location. The MapQuest api offers many possibilities for these types of searches. In Figure 4 and Figure 8, we show a simple venue search within a certain radius of either current location or from a specific address.

Mobile Worker Data Collection Application – GeoCoder Screen
A geocoder is a useful tool. In Figure 5 we show how users can type in an address, and use MapQuest to add a marker to the map of that location.

Data collection is often an important part of a field workers job. Surveyors, service technicians, pipeline inspectors are all recording data while in the field. Mobile applications are perfect both for recording and storing location based data – notes, pictures, voice records, video. They are also ideal for reviewing historic data. Let’s imagine a pipeline inspectors who on August 1, 2011 inspected a section of pipeline. He records what he sees using this mobile application. A field engineer, using the same application, views this data and makes appropriate repairs. A second inspection done on September 1, 2011 again using the mobile application, to view images and notes made a month before and by the field engineer, shows the work was completed successfully. This is a very real work flow.
Figure 6 shows the applications data screen. The search option makes a request to the company server for past data records. The search could be done by date, location or any number of other criteria.

Figure 7 shows the summary data input view. So this is a summary of the data recorded by the field worker prior to storage. The camera on a mobile device can be used to attach photos or video to the work order. Mobile devices also have voice recorders. Notes can also be included in the data stored. The data itself can be attached to a check-out, or stored locally on the mobile device, maybe for later upload to a central company server.

MapQuest have an excellent new set of mobile tools. The application discussed in this article is based on input from potential client. Those who have seen the application have been excited by the possibilities. When clients can see live demos of mobile solutions it often elicits new thinking and ideas. As mobile application developers the ideas which come from these discussions and demos are why we love what we do.
