Digitization in QGIS

Digitizing in QGIS is the most common way of making computerized vector information from existing raster information or without any preparation. This should be possible by following over highlights on a guide or picture, or by drawing them freehand. QGIS gives various apparatuses and highlights to make digitizing simple and productive.

Getting everything rolling

To begin digitizing, you should have a Vector Layer open in QGIS. This can be another layer that you have made, or a current layer that you have stacked. You can likewise digitize straightforwardly onto a raster layer, but this is by and large not prescribed as obtaining exact results can be troublesome.

When you have a vector layer open, you can begin digitizing by tapping on the Add Element button in the toolbar. This will open the Element Structure, where you can enter characteristic information for the component.

  • Digitizing Instruments
  • QGIS gives various instruments for digitizing, including:
  • Point Apparatus: Used to digitize focused
  • Line Apparatus: Used to digitize lines.
  • Polygon Apparatus: Used to digitize polygons.
  • Square shape device: used to digitize square shapes.
  • Circle Device: Used to digitize circles.

You can likewise utilize the Freehand Line Apparatus and Freehand Polygon Device to digitize freehand highlights.


Snapping is a component in QGIS that permits you to snap the vertices of your elements to existing highlights on the guide. This can be useful for guaranteeing that your highlights are adjusted accurately.

To empower Snapping, click on the Snapping button in the toolbar. This will open the Snapping Choices Discourse Box. Here, you can choose your desired highlights to snap to, as well as the snapping resistance.

Digitizing Tips

The following are a couple of ways to digitize in QGIS:

  • Begin by digitizing the main elements first. This will assist you with getting a decent comprehension of the general format of the guide.
  • Use snapping to guarantee that your elements are adjusted accurately.
  • Zoom in to the area that you are digitizing so you can see the subtleties.
  • Utilize the Fix and Re-try buttons to address botches.
  • Save your work often.
