Flexible Mobile GIS Frameworks

Thursday, January 26th, 2012


We have spoken on this blog before about the release of our free mobile GIS app called GeoMobile for ArcGIS. The link below will take you to a more detailed discussion:

http://www.webmapsolutions.com/free-mobile-arcgis-viewer-upgraded

Our logic for the release was:

  • To demonstrate a custom ArcGIS mobile application
  • Build a cross platform mobile GIS app or one code base which runs on multiple platforms; iOS, Android, Blackberry
  • Model the app on the ESRI ArGIS Flex viewer; a flexible framework allows widgets to be easily dropped into the mobile app to extend functionality

So an extensible mobile ArcGIS framework for data visualization, search, query, update/editing, data collection etc. We never imagined it to be an out of the box mobile app; a generic $4.99 mobile app. It was a first step into the mobile GIS world for a number of our engineers. And ultimately resulted in us moving from a PC Web focused application development company to fully mobile developers. So we’ve put all our eggs in one basket; mobile. Taking a risk? We don’t think so. Our focus is location data, mobile enhances what we can now provide clients. One day, not far off, we think the location and GIS community will wonder how they ever got their jobs done stuck in an office. There is another side to this, and that is the potential location and mobile presents for all apps. As Ryan Kim at GigaOM.com said in early 2011:

“We’re still a ways off from our prediction that every mobile app will have location integration. But we’re seeing that potential reality take shape more and more”

The GIS tag may be less used with time. GIS Developer may simply be replaced by Location Focused Developer.

We have digressed from the thrust of this post. In a recent article entitled ‘Hot Topics in Mobile GIS’ we reprinted some of the conversations we had with clients in 2011:

Maybe the ‘hottest item’ at the minute is online/offline mobile data collection and editing. There are an increasing number of apps now available which offer the ability to load and edit shapefiles. Many have a GIS tag; Wolf GIS, GIS Pro, GISRoam. We wrote a review of some at the link below:

and compared them in action in this video:

http://www.webmapsolutions.com/video-comparing-gis-mobile-apps

Our main finding was that most are built for iOS only. And all used the Google maps API. Google maps for GIS I hear you cry. Indeed. Google maps was never designed for GIS. The issues we highlight in the comparison video above are a result of the use of the Google maps API. So cool mobile apps built using the wrong API.

Flexible Framework using a Mobile GIS API

To build a mobile GIS application you need to use a GIS API. Extending the functionality of this mobile GIS application you need a flexible framework. To cut costs as users broaden the mobile devices and platforms they use; you need a cross platform solution.

This has become our company mantra!

Nah, but it makes much sense.

GeoMobile for ArcGIS taught us much about the future of mobile GIS. The feedback we are getting from users has guided our thinking as we move forward. Having a flexible cross platform mobile ArcGIS framework has allowed us to extend this work to fit client needs. As already said, we don’t imagine releasing an off the shelf mobile GIS app for $4.99. We build custom mobile GIS solutions to fit client needs. We work closely with ESRI, and have a good feel for what is coming in the next 12 months. This helps us gear our solutions to where they are moving.

Our next big release will be GeoMobile for GeoServer; an open source version of GeoMobile for ArcGIS. We are looking at both OpenLayers and OpenScales as potential client (software) API’s. A flexible cross platform mobile open source GIS framework.

We live in exciting (flexible) times.

Hot Topics in Mobile GIS

Tuesday, January 24th, 2012


We recently looked back over client and potential client feedback in 2011. There were definitely some re-occurring themes. Here we summarise some of these conversations:

1) Mining

We’d like to display in a mobile map app dynamic sensor data (click on map point and its shows current data)

2) Cultural Resource Management

“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. We’d like a mobile ArcGIS app to replace these systems.”

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).”

3) Natural Resources 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. Could you build a mobile GIS solution using the new mobile platforms?”

4) Civil Engineering

“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. Mobile ArcGIS or even an open source solution maybe using Geoserver would be ideal. 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 processes first by our GIS administrator before they were committed to the GIS”

5) Genealogy

We want to build a genealogical tool, which allows people to make notes, take photos etc in the field of relative gravestones. Store this data, map it, and share it. Routing would be a nice addition. We wondered whether the new mobile MapQuest releases might provide us a potential solution.

6) Outdoor Recreation Mobile App

We want to build a mobile app where users can zoom to an area of interest and see local data eg lake depth, camping facilities etc. We’d like users to be able to make notes and store them for later reference. eg. on 27th Dec I caught a trout at this location at this depth etc.

7) Invisible Car Dealer

When are new/used car searching. We want a mobile app which when turned on loads the dealerships within a certain distance. Select a dealership, allows users to browse cars on the lot. Routing to and between dealerships would be a nice addition

8) Political Campaigning

Current systems used by both political parties are archaic. Canvassing is critical in campaigning .. see blog article from this conversation:

http://www.webmapsolutions.com/android-ipad-political-campaigns

9) Fibre Optics

We use BlackBerry Playbook. We would love to have the ability to overlay our fibre lines as layers on a mobile map. Both online and offline.

10) Forest Management

A big challenge for us is viewing data in an offline mode. Tree cover may reduce GPS accuracy. Viewing and recording data while in the field will make our field workers life so much easier.

11) Agriculture Pest Control

We would love to see areas marked on a mobile map or mobile ArcGIS, which show the extent of an area last treated with a particular (pest control) chemical. So simply layer overlay. Updating this data when a new treatment is done would be the next need.

In terms of volume of requests, 2011 saw inquiries rise dramatically. The approaches came from many different sectors. Field data visualization and recording were overwhelmingly the most common themes. Many clients were looking at mobile GIS for the first time, and in many cases were looking to build proof of concept type mobile apps. Mobile ArcGIS was the most popular technology request, but we also received many approaches about potentially cheaper open source mobile GIS solutions.

As 2012 begins we see the interest in mobile ArcGIS and mobile GIS in general continuing to grow.
