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.
