Mobile GIS Demos – Endless Possibilties

Monday, November 21st, 2011


Custom cross platform ArcGIS mobile application are relatively new, but offer exciting possibilities. Using one application and running it on Apple, Android and Blackberry devices. ESRI have released their own ArcGIS mobile app which allows access to ArcGISOnline. We have been investigating custom ArcGIS mobile solutions which allow users to access existing ArcGIS layers not currently within ArcGISOnline.

Recently WebMapSolutions launched GeoMobile for ArcGIS; a free ArcGIS mobile viewer. The app is highly customizable, and allows analysis and visualization of spatial data in ArcGIS. GeoMobile for ArcGIS includes:

  1. The application reads a config file, hosted on any Web server, allowing users to add their own layers.
  2. Viewer loads dynamic, tiled and feature ArcGIS layers.
  3. Routing Widget included.
  4. Query Widget included
  5. Geocoder Widget included.
  6. Measure Widget included.
  7. Layer Widget included
  8. Overview Widget included
  9. Geolocator included

The following video in the link below shows a demo of GeoMobile for ArcGIS running on the IPad:

Offline Mobile ArcGIS

Offline GIS is an important mobile app requirement. The ability to store and access spatial data where Wi-Fi is not available. The video in the link below shows an app being used in online and offline mode. You will see both base map tiles and a shapefile stored on the mobile device and loaded in offline mode:

You might be wondering how you access GIS layers when your mobile has no Wi-FI access. Well wait no more, the solution is at hand. The demo below shows ArcGIS being used offline. Before you open source folk get upset, this solution could also be applied to a Geoserver/Openlayers/OpenScales solution. The app shows storage of base map tiles and a shapefile on the actual mobile device. In offline mode, we show loading this data. Very cool. Thanks a million to Mansour at ESRI for helping us move this forward. See the application demo in the link below:

This functionality may at some point be added to our GeoMobile for ArcGIS mobile app. You can get the current free version of the app here.

Q&A – Mobile App Development Planning

Friday, October 14th, 2011


Q. We want to build a mobile application. Where should we begin?

Before jumping in, first get a better understanding of mobile. That does not mean trying to understand the intricacies of the technology. But a good general picture of this still confusing mobile world will be a big help in the long term?

Q: I’ve tried surfing the Web to learn more about mobile, but remain confused. Is there a good source I can go to which explains in simple terms mobile and mobile application development?

Many Web mobile articles are too technical. Bu it is worth spending time looking for good introductory articles. Talking to mobile application development companies can also be a good idea. Sales and marketing people may be helpful. Better would be to talk to an actual developer or individual with a technical background. That can be somewhat daunting. But often technical folk can help demystify things. But be warned, steer them clear of technical jargon. Some companies offer free initial consultations. We’ve trained our technical staff to make consultations jargon free. We can certainly answer your questions. But don’t stop with us, talk to others. Build your knowledge base, so you have a clear understanding of all your options.

Q: Ok, I’ve spoken to a number of companies, and have a good idea of the mobile landscape. I understand I have the option of a mobile Web application or an installed mobile application. Tell us more?

A mobile Web application is like any Web application you can access from your PC. It is just optimized for mobile. When I say optimized I mean it has a simpler design (mobile screens are smaller) and built for finger interaction (as against mouse). Most people are looking for cross platform mobile Web apps, or an application which runs on all mobile browsers. That means in terms of development choices Flash, Flex, Silverlight are out. HTML5/Javascript is best choice.

Installed applications are those downloaded from the Apple App Store and Android Market. To have an application built you have two options; a native app or hybird. So for Apple a native app would be written in Objective C. Will that same app run on an Android device. Yes but only if you write it in a different language. Step up hybrid apps. These you write once and deploy to all devices. Application written in Adobe mobile AIR are hybrid. Are there advantages one over the other? Some, but maybe not enough to incur the cost of multiple native apps.

Q. Which is better an installed or mobile Web application?

That depends (you knew I would say that). Web apps are easier to distribute, just provide a URL and bingo. Write the mobile web app in HTML5/javascript and you have a cross platform solution. But try to store an image taken with a camera, and you are out of luck. Hybrid apps are available through an app store. You can charge for every download. Reaching deeper into the guts of the device, to store data in a local database is easy. Just a few examples of strenths and weaknesses. Everything depends on the apps functionality and the business model you might have in place.

Q. Can you convert a mobile (Javascript) Web application to an installed app?

Yes you can use PhoneGap. Now owned by Adobe who have promised to keep it open source.

Q: Your company specialize in building location focused mobile applications, does that mean you build mapping applications?

Certainly maps are a part of what we do. But our real focus is location. Answering questions like what or who is near me.

On the mapping side we’ve partnered with MapQuest to provide cross platform routing, traffic and local search mobile capabilities. We also work closely with ESRI to provide mobile GIS solutions using their ArcGIS product. In fact we have just launched GeoMobile for ArcGIS, a free mobile ArcGIS viewer.

But we define ourselves by location. Mobile devices have on-board GPS, so at any time the device can report where it is. That means an application running on the devices can reach out to Foursquare, Yelp or any other social networking company which shares their data. Passing current location to these provider will allow a mobile application to list data they can provide; people nearby, Mexican restaurants within 5 miles etc. We have been very involved with building apps focused on data collection by location. Field workers on site often need to collect data and link that to the collection point, surveyors, field repair crews, field technicians to name a few. Storing this data in a central computer extremely valuable and very efficient.

Q: Mobiles are still relatively new, mobile application development is both complicated and expensive. We will hold off on developing mobile apps, do you think we are being sensible?

Don’t be scared of mobile. For development the smoke is clearing. New developments by Adobe and HTML5 have helped provide less complex, simpler solutions. Mobile may well be the future of networked computing. Be careful not to be left behind.

Q. How much will a mobile application cost me to build?

Ah, the question we all want answered. Mobile app development continues to come at a cost premium. This will change with time. Depending on where you are, expect to pay in excess of $100 hr. Remember the old adage “if you pay peanuts you will get monkeys”. Hiring top development companies is what you should targeting. They don’t need to be big, but need strength and depth of experience and skills.

The development process usually looks like this:

  • Initial consultation – idea sharing
  • Planning – wireframe and architecture design
  • Design – application look and feel
  • Coding – let the nerds at it
  • Testing
  • Delivery

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.

SmartPhone MapQuest Data Collection Application

Figure 1 – SmartPhone MapQuest Data Collection 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.

SmartPhone MapQuest Check-In View

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.

SmartPhone MapQuest Data View

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.

ArcGIS on IPad, Android and BlackBerry PlayBook

Saturday, August 27th, 2011


We’ve discussed in other posts some of the the challenges of building mobile application. The biggest client requirement for all apps is that they run across multiple platform; so IPad/IPhone, Android, BlackBerry etc. Historically this required either a Web based solution written in HTML5/Javascript or multiple code bases for installed apps; Objective C for Apple, Java .. the list goes on.

New developer tools releases by Adobe have made building cross platform solutions considerably easier, and potentially cheaper. Now it is possible to build one application which can be installed and run on many platforms. Just to prove the point, we built an ArcGIS application and installed it on multiple devices. The following link shows videos of the same AIR app running on the IPad, Android and BlackBerry PlayBook. So one code base running on multiple platforms:

ArcGIS running on IPad, Android and BlackBerry PlayBook

These are exciting developments. The appeal of mobile devices is considerable. Now we can more easily build cross-platform mobile applications, we can start launching new location based tools, available to all mobile users. And built at a reasonable cost.
