Can you use advanced digitizing toolbar in QGIS?
The shapefile (trap_location) is for points, and agri_landscape is for polygons. You can not use advanced digitizing bar here because your layer isnt a geometry layer. To create a new layer with geometries you can click on “New Shapefile layer” or “New Geopackage layer” for example.
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 second polygon in QGIS?
If you already have one polygon, it is possible with this option to digitize the second one such that both intersect, and QGIS then cuts the second polygon to the boundary of the existing one. The advantage is that you don’t have to digitize all vertices of the common boundary.
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.
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 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.
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).
