What kind of editing can I do with QGIS?
QGIS supports various capabilities for editing OGR, SpatiaLite, PostGIS, MSSQL Spatial and Oracle Spatial vector layers and tables. The procedure for editing GRASS layers is different – see section Digitizing and editing a GRASS vector layer for details.
How to put the QGIS cursor into digitizing mode?
This will also check that your data source can accept all the changes. You can use the Add Feature , Add Feature or Add Feature icons on the toolbar to put the QGIS cursor into digitizing mode. For each feature, you first digitize the geometry, then enter its attributes.
What happens if you dont snap vertices in QGIS?
If you aren’t within the snapping tolerance, QGIS will leave the vertex where you release the mouse button, instead of snapping it to an existing vertex and/or segment. The snapping tolerance setting affects all tools that work with tolerance.
Where to find permissions for username in QGIS?
Outside of QGIS, open the folder that the layer is in, right-click on the layer, and open Properties > Security. Where it says “Permissions for [username]” there should be a check next to “Modify” and “Write.”

How do you digitize a map in QGIS?
You can use the Add Feature , Add Feature or Add Feature icons on the toolbar to put the QGIS cursor into digitizing mode. For each feature, you first digitize the geometry, then enter its attributes. To digitize the geometry, left-click on the map area to create the first point of your new feature.
How to edit grass vector layer in QGIS?
The procedure for editing GRASS layers is different – see Section Digitizing and editing a GRASS vector layer for details. This version of QGIS does not track if somebody else is editing a feature at the same time as you.
What kind of markers can I use in QGIS?
The current version of QGIS supports three kinds of vertex-markers: Semi transparent circle, Cross and None. To change the marker style, choose Options from the Settings menu and click on the Digitizing tab and select the appropriate entry. Start by activating the Node Tool and selecting a feature by clicking on it.
Why does QGIS load layers read-only by default?
By default, QGIS loads layers read-only: This is a safeguard to avoid accidentally editing a layer if there is a slip of the mouse. However, you can choose to edit any layer as long as the data provider supports it, and the underlying data source is writable (i.e. its files are not read-only).
Which is the most recent version of QGIS?
I generally recommend working with the most recent version of QGIS available (the current version at the time of writing is 2.6.1). Either the 32 bit or 64 bit version should work (everything presented herein was tested using QGIS 2.6.1, 64 bit, on Windows 7).
The procedure for editing GRASS layers is different – see section Digitizing and editing a GRASS vector layer for details. This version of QGIS does not track if somebody else is editing a feature at the same time as you are. The last person to save their edits wins.
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.
