Esri's Geotrigger service allows users to set location-based triggers that send messages or notifications when a device enters or leaves an area. The document discusses Geotrigger components like condition polygons that define areas, actions like sending messages, and tracking profiles that control location accuracy and battery usage. It also covers creating Geotrigger rules using geoJSON format and APIs for integrating Geotriggers with ArcGIS applications. Battery usage can be optimized using adaptive, rough, or real-time tracking profiles depending on the needed location accuracy and priority of conserving battery life.

Intro to Esri's Geotrigger Service
- 1. Intro to Esri’s Geotrigger Service for ArcGIS Aaron Parecki & Kenichi Nakamura Esri R&D Center Portland
- 5. All-day use without the battery drain Location services for smartphones at scale
- 7. Geotrigger Technology • SDKs • APIs • Battery Management & Tracking Profiles • Sample Code
- 8. Use ArcGIS iPhone and Android SDKs
- 9. Geotrigger Components • Condition (area) Polygon • Action (message, callback URL, or change tracking profile) • Tags (to group content) - Example: Wikipedia article data - Tags for Buildings, History - Can allow users to subscribe to a subset of the data
- 10. Creating a Geotrigger Rule (geoJSON) GeoJSON format
- 11. Setting a Geotrigger for a date and time Set the date and time in the dateFrom and dateTo fields.
- 13. Geotrigger Tracking Profiles Adaptive mode • Optimized for Geotrigger™ events • Will use less power when farther away from triggers and content Rough mode • Only gathers approximate location data • Good for determining if a device is in a given city or neighborhood • The most battery efficient
- 14. Data collected by one person in rough mode
- 15. Geotrigger Tracking Profiles Real-time mode • Sends accurate location as fast as possible • Least battery efficient Logging • Tracks location data in areas of low connectivity • Sends to the server later, or when a connection re-occurs
- 16. Data collected by one person in real-time mode 2.5 million points since 2008
- 17. Using Tracking Profiles This code turns the tracker into real- time mode the user arrives in a given city.
- 19. Geotrigger ArcGIS Integration Available through • developers.arcgis.com • ArcGIS Online Summer 2013

Editor's Notes

- There’s great tech out there for dedicated GPS devices and real-time tech for devices running intensive GPS for short periods, In the ordinary world – everyone wants to be location-aware, but battery drain has been an issue. Consumer devices – the devices in your pockets vs. a dedicated GPS device. I thinkeveryone in this room has troublewith GPS being a totalbatteryhog. For on the go situations, we need a solution that prevents battery-drain while still providing location-based alerts and tracking. This is consumer-grade, ready for millions of devices. Holding back the market for consumer devices to get on using GPS.
- Different from Geoevents team – with Geoevents, all the processing is happening on the server, with Geotriggers, much of it is happening on the phone.
