Mobile GIS

The smarter way to take advantage of your investment in GIS

GeoDATA 2012

Agenda• IMGS introduction• Mobile GIS

– Why use?– Challenges– Possible Applications

• Devices – Types – Disconnected versus Connected – GPS

• Examples– Dublin City Council - Road Survey– Waterford City Council - Sustainable Neighbourhood Unit – Denmark - Give a Hint

• Q+A

GeoDATA 2012

IMGS• We deliver innovative spatial solutions for the desktop, web and mobile based

on our partners technology

• Designed to meet the challenges of Government, Mapping Agencies and Utility & Communications Customers

• Our customers include OSNI (LPS), NIE, BT, OSI, ESB, Eircom and 34 Local Authorities

GeoDATA 2012

Why use Mobile GIS?• Local knowledge becoming thing of the past:

– Larger work areas – Contract workers – Therefore location information essential

• All field workers now have some form of digital device – phone laptop etc. – Need to take advantage of this expensive time

• Field capture can increase:– Data Quality e.g. GPS, photographs etc– Productivity – decrease double entry

GeoDATA 2012

Mobile GIS Challenges

• Many different Mobile GIS applications• Each with unique requirements• Rapidly developing technology• Trade offs – Capabilities– Price – Size – Ruggedness – Weight– Battery Life

• One size does not fit all

GeoDATA 2012

Mobile GIS Applications

• Utilities– Asset Locations– Asset Condition

• Local Government– Route Mapping– Incident Capture – Street furniture

• Mapping Agencies– Field Survey

GeoDATA 2012

Mobile Device – Selection Factors

• Screen size • Battery life • Weight • Transport (on foot or in car) • User training (simple or advanced) • Cost• GPS support• Connectivity• Update process (connected, disconnected)

GeoDATA 2012

Its all GPS isn’t it?

• GNSS– Global navigation satellite system – Provides location and time information

anywhere on Earth– Commonly known as GPS which are the USA

satellites– But also GLONASS (Russia), Galileo (EU) and

Compass (China)

GeoDATA 2012

GPS flavours

• But not all mobile systems provide the same GPS:– Assisted GPS• Consumer grade GPS• Uses mobile network (towers and WIFI) to quickly get

location • 10-20 m accuracy

– Basic (Standalone) GPS • Good enough for basic navigation and capture • 1-5 meter accuracy with single frequency (L1) chip • Based on simple Satellite Triangulation

GeoDATA 2012

GPS flavours

• Differential GPS– Improved accuracy – Requires a stationery

receiver (extra hardware) for 2m accuracy

– Or use DGNSS service to get < 1m (single GPS frequency

– Dual frequency (L1 & L2) provide RTK GNSS for cm accuracy

GeoDATA 2012

Connected Mobile GIS– Pros

• Server based – no client overhead • Secure – no data on device • Can act as Single device – phone and mobile GIS• Instant data updates

– Conns• Requires mobile connection – not always possible in rural areas

Disconnected Mobile GIS– Pros

• Feature rich, data rich– Conns

• Slow updated – how do you update background mapping• Client installation

Connected versus Disconnected GIS

GeoDATA 2012

• Dublin City Council required a solution to proactively capture hazard data in the city

• Dublin City Council required a full Disconnected GIS solution – Dock and Go support– Once hazards uploaded then actioned in work

management system

• Dublin City Council required an easy to use configurable form – no coding

• Mobile Expansion Pack for GPS integration – not to capture data but to move map as walking

Dublin City Council Roads Hazard Survey

GeoDATA 2012

• Sustainable Neighbourhood Unit required ability to record environmental incidents • Incidents include Graffiti, Abandoned Vehicles, Fly Tipping, Burst Pipes, Broken

Street Light, etc• Waterford required a secure mobile GIS that can instantly over a wireless connection

update enterprise systems• Aim of solution:

• Reduce delay in responding to incidents• Demonstrate to public that incidents are been resolved in a timely manner

Waterford City Council – Sustainable Neighbourhood Unit

GeoDATA 2012

Demonstration

GeoDATA 2012

• App that gives citizens a simple tool to send information to the authorities (e.g. pot holes, grafitti, broken sign posts, missing street lights etc.)

• Works on both iPhone and Android smartphones

• More than 10,000 people have downloaded the app in Denmark

• 30 local governments have signed up (nearly 30%)

• At one point the app was #1 in iTunes among Utilities apps

In Summary• A Mobile GIS can save time and money

• But there are a wide range of solutions available

• But you need to consider what is important to you and choose the solution that best fits
