Mobile GIS & LBS
Matt holds an MSc in Geography and GIS. He has been working with clients solving problems with GIS for over 17 years. Matt founded WebMapSolutions whose mission is to put innovative, intuitive GIS driven applications into the hands of new and existing users.

Apple has been praised for its innovation in the mobile space. Criticism of the company has centered around their fixation on absolute control. Their spat with Adobe in 2011 over the Flash Player plugin, effectively forced Adobe to change direction away from Flash and Flex. This was an early sign that Apple would not be playing nice. Legal pressure forced them to allow cross platform apps, like those generated in Mobile Flex, to be made available in their Apple store. But it was not a decision made to placate Adobe. Now we see attacks on rival hardware companies, like the recent Samsung lawsuit:
Mobile Platform Specific Apps
Other interesting developments include; the dropping of Google Maps in favour of Apple Maps, and the suggestion that their Maps app for iOS will include Yelp check-in feature that ties in with review site Yelp, further integrating social networking and location-based services into iOS 6.

Our thinking has been for the longest time that mobile will revolutionize the field of location-focused technology. Niche areas like GIS will be pulled into the mainstream under the location technology umbrella. Location based services (LBS) will coalesce with other location focused technologies.
As a company, we made a strategic decision nearly 2 years ago to move our focus from GIS development for the PC web, to mobile location app development. This year has been crazy busy. Combine this with Apples recent announcement, the launch of ESRI’s ArcGIS online, and new developments at Google and MapQuest, and we feel our strategy was correct; location is now at center stage in the mobile world. Making the decision when we did has also allowed us to develop expertise, and thus leadership in the location mobile app development space.

It was time for us to look into our own solution. We broke down the problem into manageable chunks, then conferred with Mansour at ESRI on the details. Let’s discuss at a high level these pieces.
Offline versus Online Mode
In code we can detect if a mobile device has online connectivity. If it does reach out over the network for map and server functionality. If offline look locally, to the device itself, for resources.
Mobile devices have varying amounts of local storage. They also come with so called lite databases. In offline mode we take advantage of these local resources.
Offline ArcGIS Visualization – Tile Packages
Let’s imagine we have an ArcGIS Online web map we wish to view on our mobile in disconnected mode. Using ArcGIS 10.1 we can now generate a tile package of the layers used in the web map. These .tpk files vary in size, we need to be careful when generating these packages, particularly thinking about the capacity of the mobile device targeted for the mobile ArcGIS app. But once the tile package has been generated this need be stored on the mobile device. Note, tile packages which include base map tiles will need agreement with ESRI since there are various licensing agreements attached to the source of these base tiles.

One thing we were excited to hear from Google was their announcement last week of an offline or disconnected mobile solution. Initially a Java for Android launch; we see this as a long overdue move. Many of our clients require offline mobile functionality. We have our own disconnected mobile solution, but it would have been nice to have had Apple announce their own offline mobile solution in their maps API. Looks like Google will remain ahead here and in many other map related areas.

ArcGIS 10.1 gives us tile packages (.tpk) so we can store tile pyramids locally on the device. Mansour has a nice example showing how to access basemap tiles using a tpk in offline mode on his blog.
The real challenge is offline editing. ESRI introduced Feature Server with Feature layers in ArcGIS 10, which work nicely in online mode. In April they released an Online-Offline Editing Sample using their iOS api. They include in their notes supporting the sample:
“For the sake of simplicity, the sample ….only allows you to add new features when the application is offline, not modify or delete existing features.”
Now there is the real challenge, what they have left out of the sample.

In the past we have leaned on the likes of ESRI’s ArcGIS Server (and their various web mapping APIs) as well as some of the more advanced open-source options like GeoServer, OpenLayers, OpenScales, etc. But things are changing. Attend any GIS focused conference and you will notice two things. First, that ESRI now talk about “non GIS users”, and not just in passing; all the time. And second that Google are usually there in one form or other. After chatting with one senior Google geo person we decided to look at their offering in greater depth.

The conference was made up of a cross section of GIS focused organisations across the state; both public and private. We were interested to see which themes were most discussed, and gauge where mobile fits into a traditionally web/desktop GIS focused conference.

First the responses. Below are a few on the comments we received:
“No. I saw this a few months ago (maybe from the same group; maybe not). This came from a location based services firm – so that’s why they want to change it. GIS is still the main term to use, for what I do at least; and folks can still use lots of sub terms if they want.”
“I’ve also heard geospatial technologies (geospatial being duplicative). But GIS includes the concept of analysis, where location does not. Location Based Solutions are applications, while GIS is analysis – how about “Geographic and Location Based Solutions?”)”
“True, I completely agree. GIS is not only a niche term, it is a discipline which occupies the time of people aged 55+ dealing with sub millimeter accuracy, INSPIRE (I prefer to call it EXPIRE), land management and maybe utilities. It has nothing to do with crowd sourcing (OSM), modern technology (mobile apps, SOA, Cloud) or “new” markets (Business GIS, LBS etc.). GIS people are still looking for that “killer app”, but cannot find it. Call it location services, Spatial Business Intelligence or whatever: the people in the industry need to change. We do still need the “55+ sub millimeter” people. Mainly for accuracy and standards.”
“I agree with most of what you have to say except I disagree that the term GIS should be retired. What I’d like to see is the use of specific terms where appropriate (like LBS as you’ve suggested) instead of using GIS as a catch-all for all things spatial. Just my two cents.”
Very interesting. Actually (counter to the first comment above) we have historically been an ESRI focused company. We wrote our first Web based ESRI map viewer (for the US Forest Service) back in 1997. Long, long before the term location based services (LBS) had been coined. Maybe this is at the crux of the discussion. Mobile has made us rethink our mission. We are a company started by geographers. Ok, we have a more diverse group together now, but geography remains at the heart of our work. Our focus is understanding better, and visualizing the space around us.
Geography, space, location, place. With my mobile in hand, I want information about what or who is near me. I want to run analysis based on my current lat/long. Is that handled by a GIS, LBS or other geo-backend? I care little, I just know that my current location is the centre of my focus. Whether I am a public utility worker trying to visualize an underground pipe (layer) and run a network analysis to find the valves which feed the pipe beneath my feet. Or I’m simply trying to see which friends are within a certain distance of my current location. With mobile everything is about location.
We are at the beginning of a geo-sector boom. Its a boom which is driven by mobile, centred on location. Nobody cares about the tags attached to the technology which provides the solutions. Users just want the solutions. And they are location based solutions.
Feel free to let us know your thoughts.

Two bold statements. We don’t necessarily believe them yet. But one would be foolish to ignore them offhand. What do these have to do with our question: “Should we retire the term GIS”?
GIS deals with location. Why not simply use this universally understood term when we sell our geo-technology solutions .. and drop GIS altogether? As the need for location technology grows, lets begin to use the language all can understand. GIS is a niche term understood by geo-nerds, often in the public sector (nothing like a good generalization).
