What we do for youWhat we do for you We 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

- 6. ““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
- 7. ““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”
- 8. ““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!
- 9. ““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
- 10. ““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

- So, which workflow is the best choice for you? Well, it will likely vary from project to project. Some key factors to consider are: Will you have a constant, reliable broadband connection in the field?If not, you won’t be able to support a connected workflow. If you know you will have a stable connection at various times throughout the work day, consider an occasionally connected or disconnected workflow.Taking advantage of an occasionally connected workflow can potentially save you that end of day trip back to the office.
- Will you be starting each day in the office and returning to the office anyway?If so, the extra cost of mobile broadband data and the hardware that supports it may not be worth it. Since you’ll physically be in a place where data can be synchronized before and after each day in the field, a disconnected workflow may provide everything that you need. Keeping data in sync with other users in your organization throughout the day would be the main reason to consider a connected or occasionally connected workflow in this scenario.
- Will other people need to review or edit your datasets while you are working with them in the field?If so, you’ll need to go with a connected or occasionally connected workflow in order to keep field data in sync with the rest of your organization. A disconnected workflow will leave others in the dark while you’re out in the field and can even result in edits being overwritten due to a “last in wins” policy on check in.
- What hardware and data contracts do you have or plan to purchase?Do you already have internal/external mobile broadband cards or mobile hot spots, along with data plans, for each field user? Do you already have ArcGIS Online user accounts for each field user or an ArcGIS Server license? Do you plan to purchase these items/services? For larger organizations, these costs may be minimal relative to the productivity gain. But for smaller organizations, connectivity from the field can be expensive. On the other hand, occasionally synchronizing over Wi-Fi at a coffee shop or other free Wi-Fi source can help support a viable occasionally connected workflow.
- By creating a seamless workflow and utilising smart sensors and platforms, the best combination of non-invasive and traditional measurement sensors can be built into a single solution.
- The Global Positioning System (GNSS) is a constellation of about 30 NAVSTAR satellites – with the full constellation being a minimum of 24 satellites. The technology provides worldwide position coordinates via the use of GNSS receivers.
- An SBAS provides correction data for visible satellites. Corrections are computed from ground station observations and then uploaded to geostationary satellites. Corrections are referenced to WGS84. This data is then broadcast on the L1 frequency, and is tracked using a channel on the GNSS receiver, exactly like a GNSS satellite. WAAS, EGNOS, and MSAS are examples of satellite-based augmentation systems.
