In our fourth article in this series: Offline Mobile Map Basics 4: What are your Choices?, we pulled all together and discussed your options for working with mobile maps. The different types of offline mobile map apps were discussed: web. hybrid and native. In this, our last article in the offline mobile map series, we will provide use cases or examples of offline mobile map apps.
Mobile maps and GIS are confusing. As we discussed in our last article, there are 3 mobile choices: web, hybrid and native. Given the problem you are looking to overcome which is your best choice? And, more than simply mobile, what is your best choice for offline?
Let’s consider 3 use cases. In each case a different approach is taken to provide an offline mobile map solution.

In our third article in this series: Offline Mobile Map Basics: Editing Map Layers Offline, we discussed editing map layers when offline. Layer feature add, update, delete and attachments were at the core of the conversation. In this, our fourth article in the offline mobile map series, we will pull all together and discuss your options for working with mobile maps.
Offline Mobile Map Basics: What are your Choices?
Today there are three mobile offline ArcGIS choices: web, hybrid and native. Each has its own own advantages and disadvantages
1. Offline Mobile Map Web Apps

Mobile adoption in the GIS world has taken place slower than many would have expected. The GIS landscape is changing so rapidly, mobile was just one more ball to juggle. But things have begun to change. We are now in a world of multiple devices. And not just smartphones and tablets, also wearable’s, smart TVs etc. There is increasing demand to have access to GIS anywhere, on any device.
Today there are three mobile ArcGIS choices: native, hybrid or web. Each has its own own advantages and disadvantages. If you are looking to have a mobile ArcGIS app developed the right approach need be made on a case per case basis. In this article we will discuss these 3 options; the pros and cons.
Mobile ArcGIS Choices: Native, Hybrid or Web
1. Native ArcGIS Mobile Apps
Native ArcGIS mobile apps are developed specifically for one platform. They are written in the native language of that platform. So Objective-C for Apple (iOS) devices, Java for Android, .NET for Windows. Functionality, user experience and performance are key advantages of native ArcGIS apps. But they are more complex and expensive to build and are not cross-platform compatible. A typical use case for a native ArcGIS mobile app would be: “We will only ever use iPads in our organization, and we are working with large data-sets. Performance is key”.

In our first article in this series: Basics: Offline Maps and How to Get Started Part 1, we provided background on offline maps. We discussed the difference between base-maps and layers, and covered what are interactive and editable map layers. In this second post in the series we will discuss how we take base-maps and layers offline.
1. Taking Base-Maps Offline
For this conversation we will focus much of our attention on ArcGIS. Note, the same basic principles discussed here will apply to other map and GIS offerings. So what is a base-map? It is a series of pictures or tiles combined into a single image. Rather like a jigsaw puzzle. And just like a jigsaw puzzle a single image is usually broken into smaller pieces. Think of a huge satellite image. Take a cookie cutter and break that up into smaller chunks. These are tiles.
So why generate tiles? Improved user experience that is why. Google in 2005 released Google Maps. Suddenly we could pan and zoom satellite images for free on the web. And yes the first thing I did was zoom in to see my house. But take a closer look at Google Maps or an ArcGIS web map today. You will see the individual base-map tiles as you pan and zoom. Your experience is seamless and super fast. Imagine each time you panned the map, just for a moment the map disappeared, then reappeared with the new extent. That was the pre Google Maps reality.
So how does this relate to offline? To be able to use base-maps in areas without wireless connectivity we need to copy these tiles to our smartphone or tablet. In Esri-land this can be done dynamically (see Collector for ArcGIS and the base-map selection option for offline) or through a tile package or TPK. This is simply a zip file of images. Tiles at different zoom levels: a “pyramid” of images.
Why tiled maps? from Penn State is a good article on this subject, well worth reading.

I was thinking yesterday about the phrase “I know enough to be dangerous”. Its one ever more applicable to GIS. As more organizations and individuals adopt the technology, knowing just about enough (or not) is ever more common. And its a problem!
Biggest GIS Barrier is Lack of Understanding
The fact that GIS has become easier, does not mean GIS is now easy. I write about this often, but it is so true. And I see it so often. Organizations looking to solve problems with the new distributed model of GIS (Web GIS) and flailing. Its why I’ll say again
The Biggest GIS Barrier is Lack of Understanding
GIS was a niche technology. Used by GIS trained staff. Answering both simple and complex ‘where’ questions. GIS trained staff are essential to the future success of GIS. Not to promote GIS but to prepare and apply GIS correctly. As a company we work on both small and large projects, and in both cases we are seeing a lack of understanding as being a huge barrier. We spend as much time educating as we do implementing. Now don’t get me wrong, we love educating. But with sometimes tight deadlines this process, particularly when working with other implementor’s, can be challenging. Its one reason we introduced our GIS Solutions Engine, to help move projects forward efficiently and ensure all are on the same page.
In the push to promote GIS technology, adoption is beginning to happen before understanding. That is a worry. More emphasis need be put on helping organizations and individuals solve their business problems without the technology itself being just one more barrier.

Let me start this blog post with an age test. Do the following lines of dialogue mean anything to you?
“Oh, the pain, the pain”
“Where are you my hairy friend?”
“You Deplorable Dunderhead”
“Nickel Plated Nincompoop”
This will mean nothing to the younger generation. But to some of you (and yes I can see you smiling) this means Lost in Space. Forget the movie remake, this was one of the greatest American TV sitcom’s ever made. Filled with terribly wooden actors, predictable story lines, comical monsters (many also seen in Voyage to the Bottom of the Sea’), cheesy sets .. I could go on. ‘Great American TV sitcom?” I hear you ask. Without question. Why?
Dr Smith that is why!
A simply marvelous character: sneaky, underhanded, greedy, lazy, cowardly. He stole the show. Dr Smith was the reason we watched.

I’m troubled by fixed mindsets. Whether that be personal or corporate. I’m old enough to have experienced the dot com boom. Embedded tech ideas driven mostly by internal ‘brilliance’ than solving real client problems. The ‘if we build it they will come’ approach. Rather like the film Field of Dreams. Fiction!
GIS Technology on its own is Useless
I like the title of this blog post: GIS Technology on its own is Useless. We could take the GIS part of that title away. Technology helps to solve problems. It is not a solution on its own. Read that again.
If we throw technology over the fence at users/clients/colleagues does that solve their problem?
Today’s GIS technology is incredible. But it is only as useful as the problems we know how to solve using GIS. On its own GIS is useless.

A GIS solutions engine: state the problem and with the simple press of a button …. out comes your answer. Sounds too good to be true. I bet I have you wondering where you can get this wondrous technology.
What is a GIS Solutions Engine?
There is little doubt that GIS has become easier. Releases like ArcGIS Online have greatly simplified the process or mechanics of generating and publishing maps. There are now many configurable (that means you don’t need to build from scratch) web and mobile applications which come with these platforms. Now anybody can set up and help provide answers to where questions with GIS. Right?
Well… definitely, maybe!
From our experience with customers, if you do not have in-house GIS expertise or are not prepared to spend time learning GIS ….. answering your business where questions with GIS might not be so easy.
