In today’s talk we show you how data is collected offline using TotalPave’s PCI and IRI applications. Ensuring that your data collection is completed even on the most remote rural roads with no cell-service.
The quick answer to the question, do you need cell service to collect data using Totalpave, NO!
Our offline functionality is designed as a failsafe for those sections of your survey in rural areas that may have service dead zones. A secondary benefit is saving you money on your smartphone data plans.
The PCI application offers automatic and instantaneous calculation and upload when connected to the internet. But if you’re out surveying in a spotty service area, you are able to do so without internet connection. When collecting data without service, the sample will indicate that there is no data connection by turning grey, but will still save all of the information and distresses entered. This saved data will automatically calculate and upload as soon as you reenter a service area. This allows you to collect and complete your road survey, with all of your data saved, and no need to run up a mountain in search of service.
IRI data collection is completely automated and does not require any internet connection whatsoever during data-logging. The application collects your accelerometer and GPS data for the IRI calculations, which neither require internet connection. I will note though, that if data is available on your smartphone, it is best to use it as it improves your GPS accuracy.
Step 2 is uploading the IRI logs to the web portal after they have been collected which does require an internet connection, all data is stored on the device until you choose to upload. The logs themselves are fairly small, although automatically uploading them could eat into your smartphone plans, so there’s no need to do this in the field using a data plan unless you want to. You can collect all of your data in the field and wait until you’re back at home or in the office to upload the data on WiFi.
