Intterra data is automatically loaded to your device as local storage so that it’s available to view and edit if you lose internet coverage.  There are limits to how much data your device can store and utilize effectively.  Also, loading of the data takes time away from your ability to view and edit.

The Field Tool measures the amount of Intterra data, as well as the frequency of updates for each layer, to keep the app running lightly and efficiently.  These auto-cache settings are managed by Intterra.
  • What is loaded? – The amount of data is determined by a radius from your current location (so that you have data for your vicinity).  The radius varies, by layer, from 500 meters to 500 kilometers based on the current or potential amount and complexity of the layer.
  • When is it loaded? – When you have internet service, data is loaded to and from your device:
    • When the app is opened.
    • When a layer is turned on.
    • Automatically, based on time.  The refresh time varies, by layer, from 150 seconds to never based on whether the data is dynamic (incident data, mobile units, etc.) or static (preplans).
    • Automatically, based on distance traveled.  The refresh distance is generally set to update when the user travels half the distance of the radius so data is available.  However, it is disabled for layers that will normally update before the distance is traveled – i.e., a large radius or frequent update times.
The auto-cache settings are available for you to see by tapping the right arrow next to the layer name.  You’ll then have access to the legend and the auto-cache settings – radius, refresh time, and refresh distance.
