# Syncronizing Surveys

Site survey data can exist in three places:

1. On the Hamina Clip survey device
2. In the Hamina Onsite app on the iPhone, iPad, or MacBook that is being used to survey
3. On the Hamina Cloud

In the project, the syncronization status can be viewed with the Sync Indicator.

## Survey Device to Hamina Onsite

**Oscium Nomad**: all site survey measurements are streamed from the Oscium Nomad to Hamina Onsite app (on the iPhone, iPad, or MacBook) over USB. No site survey data is stored on the Oscium Nomad.

**Hamina Clip connected with a USB cable**: All site survey measurements are streamed over the USB cable to the Hamina Onsite app. No site survey data is stored on the Hamina Clip.

**Hamina Clip connected with Bluetooth**: In some cases, site survey data may be temporarily stored on the Hamina Clip, and will be opportunistically streamed to the Hamina Onsite app as time and bandwidth allow. In some cases, syncronization will be instantaneous. In other cases, it can take a few minutes. If the syncronization is interrupted, Hamina Onsite will alert you, and the sync indicator will prompt you to reconnect the Hamina Clip.

## Hamina Onsite to Hamina Network Planner

During a site survey, if Hamina Onsite has internet access, the position of the surveyor is streamed to Hamina Network Planner in nearly real-time. While the position will update in real-time, the measurements will not. Hamina Network Planner must be refreshed before measurements will appear.
