Geo IT in the Era of Connected Devices

A developer guide through a ubiquitous, but barely visible world of geo-aware sensors and systems changing the world of today

Location-aware Devices in Time

What has changed?

• Visual interfaces are not needed (e.g. WIFI access as with AR Drone)

• Decoupling data generation and processing• Data aggregation happens continuously• Data accuracy has increased (more data!)• Form factors get smaller • Devices are always on• THEREFORE: Power demand increased

Architectural hints

• Move all computing-heavy tasks in the cloud• Have a failback strategy, when systems

shutdown and/or communication is unstable• Provide non-visual health monitoring

interfaces (REST API at best)• For all life-safety / urgency systems have at

least one backup device always available

Tech challenges

• Battery life is limited, so avoid bloated architectures and heavy game loops

• Performance is one decade behind, see #1• Assume unstable environments / networks• Use your development language wisely• Rugged systems need to be tested in tough

environments (e.g. +60…-35°C)
