  • Introducing GoMoGi – a Carinthian GIS start-up

    0

    GoMoGi is an start-up company located in Klagenfurt, Austria. It was founded about one year ago by Michael Diener. GoMoGi covers the area of GIS services and Location Based Service (LBS) applications. Beside support for different kind of GIS support GoMoGi developed a software called GoBiz, which is a simple field data collector running on a Windows Mobile smartphone.  For example this software can be used in the areas of Road maintenance and planning, Sand and salt spreading, Snow plowing and removal, Sanitation services, Street lighting, etc. Watch the video to see a demo of the application:

  • Location Based Decision Services

    Tomorrow I will do my thesis defense. The topic is the “Development of a distributed Service Framework for Location-based Decision Support“. Here you can see the slides to this presentation. They are not the final version but almost. There were also some difficulties to convert them from the PPTX format in the online format of a slidehoster – So maybe some of the slides look a little bit wired.

    For more information on the topic look at: http://www.joesonic.com/2_master_en.php. If someone is interested in my whole master-thesis please inform me to get an copy in pdf.

  • Development of a distributed Service Framework for Location-based Decision Support

    Finally, it’s finnished: My Master Thesis.

    Topic: Development of a distributed Service Framework for Location-based Decision Support

    Year: 2008

    Abstract:

    Progresses in the field of mobile Internet and usability of mobile devices have lead to new opportunities for location-based services. This thesis proposes the integration of multi-criteria decision analysis for mobile location aware applications. Location-based services equipped with decision support techniques provide users with a valuable extension in functionality and usability.

    Humans make decisions day-to-day. Most of these decisions are related to a specific time and their current environment. People also tend to decide about problems when they occur and straight near the relevant location. In such cases mobile spatial decision support systems have significant advantages over traditional spatial decision support systems. Location-based decision services assist people in their decisions while they move through a physical environment. Such systems explicitly use decision support methods to suggest decision alternatives based on user preferences, the combination of multiple criteria and the current location.

    For the research in mobile decision support theoretical aspects about decision analysis and actual trends in mobile computing and location-based services are evaluated and compared with each other. There is a momentous influence of the Internet and web-based technologies in both research areas. Hence, the most obvious design for a location-based decision service is open and distributed processing. This work introduces a comprehensive conceptual framework for implementing a location-based decision service. This framework is based on an n-tier software architecture, which is described from different viewpoints. Geographic information is a valuable resource for spatial decision making. Trends from the Web 2.0 fundamentally affect the geoinformation community. Due to user-generated content and volunteered geographic information we face an unheard-of ampleness of available and accessible information, useful also for decision making. The introduced prototype application combines user-generated content and expert data for evaluating suitable locations. The user has the possibility to rate different criteria on a mobile device to get a personal suggestion of decision alternatives. In this case the use of decision support enhances the personalisation of the location-based service. The application domain of the introduced prototype is tourism.

  • Why is there no Navi for the iPhone?

    0

    Apple has introduced a SDK for the iPhone. So everyone should have the possibility to create own applications for the iPhone. Based on this information it should be obvious that a lot of companies will try to port their navigation solutions to the iPhone. The preconditions are very good because of the large screen and the touch interface it reasonable to implement a navigation software. There is also a build in GPS in the iPhone 3G. Apple provides only a Google Maps application where the user can visualize the own location.

    But why is there no Navigation software?

    Apple restricts the use of GPS data via the SDK. Hence, Location Based Services (LBSs) and Navigation software cannot (or only hardly) be buid by third party companies. In my opinion Apple wants to create their own navigation solution and prevent competing companies. Big companies like TomTom have announced navigation software for the iPhone (some sources clam that the software is ready to roll), but until now we have to use the Google Maps application.  Another reason could be a contract (or licences issues) with Google and that Apple and Google want to built an exclusive application for navigation.

    We will see who will bring real navigation to the iPhone and how it will look like.

  • Best Phones for Location Based Services

    2

    What are the best mobiles for LBS? To answer this questions I have taken four phones from different manufactures and compared them. In my opinion following issues are important if you want to use a mobile for LBS applications:

    • buid-in GPS
    • large screen size and resolution
    • fast internet connection
    • good usability and operating system which allows to design own applciation easily
    • battery life
    • prize

    Maybe there are some more criteria to rate phones for their LBS suitability.

  • Concept Phones and Locational Services

    0

    From time to time new concept phones like this Nokia 888 are presented to give a preview into the future of mobile devices. Most of them were never realized but the interesting thing is that most of these presentations include a mapping or location based service applications.

    The question is how will these services be implemented in order to fullfill the requirements of individual users? How can personalization work in order to support people in their decisions about tasks related to space? On the other site how can locational privacy be ensured? In my opinion these are very interesting questions and I will try to focus on this during my master thesis.

  • Is there Potential for Location Based Services (LBSs)?

    0

    Worldwide subscribers to location-based communications services on mobile devices will increase by nearly 168 per cent in 2008 while revenue will grow by 169 per cent, according to Gartner, Inc.

    Figure 1: Current numbers and estimation about subscibers for location based services (LBSs) and revenue in the field of LBSs.

    “Location-based service technologies have been around for several years but they have not experienced the rate of success that was anticipated at the beginning,” said Annette Zimmermann, a research analyst at Gartner. However, she said: “The market for location-based services is at a turning point, with indications of mainstream adoption in the next two to five years.” Gartner said the number of subscribers worldwide will rise from 16 million in 2007 to 43.2 million in 2008 and revenue will rise from $485.1 million in 2007 to $1,307.3 million in 2008. The number of subscribers is expected to reach nearly 300 million in 2011 and revenue is forecast to top $8 billion in 2011.

    People are familiar with the small, satellite-based, GPS navigation devices in vehicles. Many want the same or similar services outside their vehicles and on their mobile phones. Increasingly, mobile phones are including GPS capabilities to supplement the less precise location sensing that is an integral function of all cellular systems. As the technology has improved, other services become possible, such as navigation for tourists and pedestrians, child location, find-a-friend and local directories and advertising.

    Ms Zimmermann said: “Growth now will be stimulated by the arrival of mobile phones with built-in, precise location sensing and the arrival of new service providers, like Google and Nokia with its service offerings, keen to exploit geographic and positioning technologies.” Different forces are driving technical developments and patterns of adoption in different regions. In the United States, the government ruled that mobile phones should always be able to call an emergency number – enhanced 911 or E911 – and this has stimulated accurate positioning facilities. In Europe, the drive has come from consumer demand and the efforts of handset manufacturers and service operators. In the Far East, telecommunications carriers stimulated widespread adoption, particularly in South Korea, at the beginning of the decade and they have been broadening the range of services.

    “The potential of this market will drive handset vendors, carriers and other service providers to compete with each other and new entrants will appear. Increased competition will reduce subscription prices,” Ms Zimmermann said. “The value chain is complex and fragmented and vendors will need to form alliances.”

    Additional information is available in the Gartner report “Location- Based Services Subscriber and Revenue Forecast, 2006-2011.” The report is available on Gartner’s Web site at www.gartner.com/DisplayDocument?ref=g_search&id=590907&subref=advsearch
