Which is the plugin for tracing in QGIS?
Visit the QGIS Trace Digitising page for more information. Users of QGIS 2.12 or earlier can still get tracing functionality by using the AutoTrace plugin (see below). AutoTrace is a plugin for QGIS that allows users to digitise new features based on vertices from existing features.
How do you snap to a feature in QGIS?
Now in your QGIS settings you will need to decide how you wish to SNAP to features. Choose the Settings > Options menu and then the Digitising Tab. Next choose to open the Snapping Toolbar and select the Enable Snapping tool (magnet). Now hover your cursor in the map to snap to a feature to start digitising.
What happens if somebody edits the same feature in QGIS?
This version of QGIS does not track if somebody else is editing the same feature at the same time as you are. The last person to save its edits wins. For an optimal and accurate edit of the vector layer geometries, we need to set an appropriate value of snapping tolerance and search radius for features vertices.
Do you have to digitize all vertices for QGIS to work?
The advantage is that you don’t have to digitize all vertices of the common boundary. If the new geometry is totally covered by existing ones, it gets cleared and the new feature will have no geometry when allowed by the provider, otherwise saving modifications will make QGIS pop-up an error message.
How can I get GPS tracking on my QGIS?
Easiest way to make it work is to use a middleware (freeware, not open) called GPSGate. Launch the program, make it scan for GPS devices (works for both USB and BT ones) and then in QGIS just click [Connect] in the Live tracking panel using the Autodetect mode.
Do you need gpsd for GNU / Linux QGIS?
For GNU/Linux, gpsd support is integrated to support connection to most GPS receivers. Therefore, you first have to configure gpsd properly to connect QGIS to it. If you want to record your position to the canvas, you have to create a new vector layer first and switch it to editable status to be able to record your track.
