Export Data#

Tracks recorded in the NextGIS Mobile application, vector layers, and their attachments can be exported as files.

Depending on the applications installed on the device, you can:

  • Send the file by email or via messenger.

  • Upload the file to a cloud storage, such as Google Drive.

  • Send a file to another device via Bluetooth or LAN access.

  • Save the file to the device’s memory.

You can also send vector layers created in the application to your Web GIS and enable track synchronization with the server.

When you upload a layer to the Web GIS , attachments are automatically uploaded to the server.

When you save a layer to your device as a file, the photos are added to an archive. Each feature has a corresponding folder that has its ID as the name.

Example entry:

(4:10000002.jpg,10000000.jpg,10000001.jpg,10000003.jpg)

What it means:

4 photographs with the following names are attached to this feature. These photos are in the folder named with the object ID.

Export tracks to GPX#

Recorded tracks can be exported to a file, for example, to create a backup.

  • Select the squiggle “My Tracks” layer in the Layer Tree.

  • Open the layer menu by clicking the three dots tree dots next to the layer and click List.

  • A list of recorded tracks is opened. If several tracks were recorded on the same day, the tracks will be broken down by sessions. If one track was recorded over several days, then the recorded track will be split into parts at midnight.

  • Select the track by placing a checkmark next to it. Action buttons for tracks will appear on the top panel.
