Mobile GIS & Resource Management

Tuesday, January 17th, 2012

Mobile GIS in Archaeology and Historical Preservation

Cultural Resource Management relates to archaeology and historical preservation. We had a recent email from somebody working in this area – thanks Stephen – who discussed how mobile applications, particularly those which utilize GIS, would be a huge help.

Stephen sees an important place for mobile GIS apps in the world of archaeology and historical preservation. He writes:

“Even though GPS technology has been readily adopted in the profession, it is still mostly wedded to a system of paper forms and (often) disconnected implementations of ArcGIS based map creation and non-geo-referenced photos”

This reminds us of many other areas where paper and pen remain the field recording equipment of choice. Mobile apps allow users to record data using tablet based forms, and basic geo-referencing. Combine this with GIS and a wide array of tools become available. Stephens cites some examples:

“If one is recording an historic building or archaeological sites, one can take a decent resolution image, complete the form electronically, and consider view shed/buffering without juggling several devices and a handful of forms as well. I can also see value when doing a field inventory for something like a wireless tower where viewsheds and buffers are important. It would also be very useful for situations where one is doing resource monitoring (making sure a client doesn’t impact something).”

Mobile GIS in Natural Resources Management

Another recent conversation we have had revolved around natural resource management:

“We have a diverse natural resources management program going on here, and I can see this used for several of our field activities. Particularly of interest, though, is using this for collecting survey data. We are currently doing things horribly old-fashioned: collecting GPS points and logging attribute data on paper forms in the field, then coming back to the office to download points and enter into a database.”

“We collect a few different types of data during surveys: any threatened or endangered species, all species present for certain transects, and incipient and invasive species. Spatial datasets are then updated as needed. It requires a lot of attention just to make sure data gets organized properly. For years, we’ve talked about getting a nice set of Juniper systems with ArcPad, but it’s a pretty big investment. The proliferation of mobile devices, and new mobile GIS apps, seem like a more cost-effective means of achieving similar functionality.”

Mobile GIS in Civil Engineering

Finally civil engineers are looking for solutions to improve how field workers record and update data:

“We simply want an easy way to update our GIS from the field. To overlay pipeline and manhole layers for example on a basemap, and view on an IPad, would be a big benefit to our field crews. More than that, if we were able then to update a GIS where we see inaccuracies in both the path of the pipeline and attributes of a manhole, that would be simply huge. We would want a sanity check. Whereby any updates were processed first by our GIS administrator before they were committed to the GIS”

Mobile GIS Solutions

With an increasing number of these types of inquiries, we have been looking at the implementation of solutions. The link below is to a video showing an online/offline feature editing solution:

Mobile GIS Editing

We are actively looking at building GeoMobile for Geoserver (we already have released GeoMobile for ArcGIS), an open source mobile GIS viewer. Feature editing as described above will be an important consideration.

Mobiles & Field Data Collection

Friday, September 9th, 2011


Recently we’ve had considerable interest in mobile application development based around check-in and mobile data collection. Facility management companies, surveyors, multi-level marketing, insurance claims, pipeline companies, water utilities; all have field workers who would benefit from mobile applications. Not only checking in to work sites, but keeping a record of the work done; notes, pictures, video, even voice records. To help with our discussions with these potential clients, we put together a demo which pulls together much of this proposed functionality. We have included in this article both screen shots of the key functionality in the demo, plus a video of the actual application.

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.

Mobile Worker Data Collection Application – Data Screen

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.

Summary

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.
