About usAbout us

What we do for youWhat we do for youWe help organisations choose the right mobile GIS solution by:

•understanding your requirements•providing independent advice•considering the most cost-effective approach for you•reducing your risk when building a business case and•supporting throughout the project lifecycle

Which Mobile GIS workflow is best for you?

Are you….

•Connected…•Disconnected…•or Occassionally connected?

““Connected” WorkflowConnected” Workflow

• Typically consist of web applications running on a mobile device or tablet

• Rely on an active connection to the internet

• No connection = no application/data• Lost time in the field• Relatively rare nowadays

““Disconnected” WorkflowDisconnected” Workflow

• More traditional Mobile GIS• Do not use/need an internet connection• Data is loaded at start of day/project• All functionality supported in application

• (display, query, capture, edit, etc.). • Captured data is transferred to a

desktop PC or emailed to the office• Some have connected capability via

“Dropbox”

““Disconnected” WorkflowDisconnected” Workflow

• Tend to be licence-based• Full suite of mapping functionality

• GIS Mapping to Surveying• Cost £250-£1000+ per licence

• Annual software maintenance• eg. ESRI ArcPad, Digiterra, Terrasync

• Microsoft now extending support for Windows Mobile (WEHH) until 2020!

““Occasionally Connected” WorkflowOccasionally Connected” Workflow

• Best of both worlds• Use active internet connection to

send/retrieve edits to the cloud or secure server and retrieve new data

• When disconnected, data is cached locally

• Application functionality works in connected and disconnected mode

• Synchronisation occurs in the background when connected

““Occasionally Connected” WorkflowOccasionally Connected” Workflow

• Tend to be subscription-based• Cloud-based

• Not all have private cloud capability• Limited mapping functionality

• Cost £15-20 per user per month• Spread the cost over the project

• ESRI Collector/ArcPad/ArcGIS Mobile• Terraflex• Terrago Edge• MGISS Custom

““Best of Both Worlds “Best of Both Worlds “

This is Bill

Bill is occasionally connected

Bill can use an active internet connection to send/retrieve edits to the cloud

Bill can still edit data when not connected

Bill has cached data!

Bill is SMART

Be like Bill

Which workflow for me?Which workflow for me?• Will you have a constant reliable

internet connection in the field?

• Single (large) site with excellent WiFi• Or Urban areas with WiFi Hotspots• If not then need to consider something

else

Which workflow for me?Which workflow for me?• Do you return to the office each day

or frequently?

• If yes then a disconnected workflow would likely be most cost-effective

• No concern with remote synchronisation or data costs

• If no then further consideration is required.

Which workflow for me?Which workflow for me?• Do you need to send data back

while you are on site?

• If yes then an occasionally connected workflow would likely be most cost-effective

• Typically field teams syncing data remotely with central office/each other

Which workflow for me?Which workflow for me?• Do you already have a corporate

mobile data plans and GIS systems eg. Large ESRI customer and need to send data back while you are on site?

• Mix of disconnected and occasionally connected apps to suit the end-user but based on the same workflow

• Remote synchronisation or data costs minimal relative to the gains in productivity

Accuracy ConsiderationsAccuracy Considerations

• Accuracy requirement• Choosing the relevant GPS/GNSS• What accuracy do you REALLY need• Higher Accuracy = Higher Cost ??

What is GNSS ?What is GNSS ?• GNSS stands for Global Navigation

Satellite System.• Current operational GNSS constellations

include:• GPS – Global Positioning System (US

Dept of Defence). • GLONASS – GLObal NAvigation Satellite

include:

• BeiDou – Chinese constellation. Fully operational in Asia-Pacific since 2012. Worldwide coverage by 2020

• Galileo – EU/European Space Agency constellation. Still in development. Full service by 2020
