mobile gis
Mobile GIS
  • Mobile GIS refers to the access and use of GIS data and functions through mobile and/or wireless devices.

(Notebooks, PDA, tablet PC, Pocket PC, etc.)

  • WHY mobile GIS
    • Field works: data collection and validation process, coupled with GPS and wireless communications.
    • Real-time update / change
    • GPS integration.
environmental monitoring and natural habitat managements
Environmental Monitoring and Natural Habitat Managements
  • TASKS:
    • The adoption of remotely sensed images
    • The analysis of habitat changes (land cover)
    • Monitoring multiple plant and animal species across regions.
  • PROBLEMS:
    • Field survey and data acquisition are difficult, time-consuming
    • Traditional RS and GIS software are very expensive, difficult to use.
    • Regional program managers and park rangers seldom have the necessary resources or training to access RS/GIS data
    • There is a strong need to develop an easy-to-use, inexpensive set of field survey tools
internet map servers and wireless communication
Internet Map Servers and Wireless Communication
  • WHY Internet Map Server (IMS)?
      • The storage problems in mobile devices (too small)
      • Multiple users access
      • Data Update for multiple users at the same time.
  • Internet Map Server  Intranet Map Server
  • Local access ONLY via Wireless LAN.
  • (Wi-Fi or Wi-Fi5 broad bandwidths)
slide5

Wireless Local Area Network (WLAN) IP address-based (130.191.118.30)

  • No Internet Connection.
  • Different from cellular phone communication (CDMA, GPRS)
  • Fast Transmission Speed, Good for GIS applications (large size of data/images)
    • Wi-Fi (802.11b, 11Mbps, 2.4 Ghz),
    • Wi-Fi5 (802.11a, 54Mbps, 5GHz). (next  802.11g)
slide6

Internet Map Server on notebook computer with wireless access port.

Field workers: Pocket PC, GPS, and wireless card.

Wi-Fi wireless communication

(up to 300 feet)

Integrated System Framework

(Internet Map Servers, GPS, Wi-Fi, Pocket PC, Vehicle)

Autonomous Unit:

Independent, Portable, Reliable

Mobile unit mounted on a vehicle.

Mobile unit with Portable Battery

slide8

User Scenario:

Environmental Monitoring and Management

Mission Trail Regional Park (short movie)

system implementation
System Implementation
  • Hardware:
      • Notebooks (Web Server + ArcIMS)
      • Pocket PC (Clients + Wi-Fi compact flash card)
      • GPS (with serial cables to Pocket PC)
      • Wireless Access Point (Hub)+ Twisted Ethernet Cable (directly from Server to Hub)
  • Software:
      • Server-side: IIS 5.0 + ArcIMS 4.0
      • Client-side: ArcPad 6.0, Pocket IExplorer, FTP
  • Network Setting:
      • IP Address  NO Domain Name System (DNS)
slide11

User Scenario Testing (Jan 15, 2003)

Use GPS and remote sensing data to identify a new location of invasive plants (pampas grass)

current limitations and problems
Current Limitations and Problems
  • Wireless Technology is changing fast.
  • The short range of current commercial WAP devices (300 – 1000 feet)
  • Limited Software Customization Capability (only user interface customization, no system function level, such as direct data upload)
  • Pocket Internet Explorer (No Java applets capability)
  • No Vector-based IMS for Pocket PC
research agenda
Research Agenda
  • Explore other potential GIS applications(virtual tour guide, homeland security, emergency rescue, etc.)
  • Enhance Information Security– Wireless Communication. (for sensitive data) PDA: Fingerprint ID.
  • Data Transmission Efficiency (compression techniques)
  • User Interface Design (Different from Desktop PC)
  • Smart Display for different devices (Software Agents)
slide15

Possible Applications:

    • Police Department Emergency Rescue
    • Border Patrol Agency Homeland Security

Intelligent Mobile ServicesSoftware Agents for Mobile GIS
  • Software Agent help users to access requested data / images from ArcIMS Server (100 GIS layers).
  • Software Agents convert the original display setting for Desktop (1024x768) to Pocket PC resolution (300x240).
  • Automated Data Conversion / Integration.
