How to extract zones that are contained in bigger zones from two different layers
Geographic Information SystemsHow do I isolate an area in Qgis?
Quote from video: Features button and click it and go to select features by area or a single click click there and now you can select the area you want when it gets selected uh it will appear in yellow.
How do I subtract one layer from another in Qgis?
How can I do this? If both polygons are separate features, you can delete the small one via the Attribute Table (right-click the layer), toggle the Editing icon (looks like a pencil), select the feature of the polygon you wanted deleted, then select Delete Feature. Thank you.
How do I compare two shapefiles in Qgis?
1 Answer
- Loop through the first feature collection.
- Find any geometries in the second collection that intersect with the current feature.
- Union those together (if there are more than one) and subtract (difference) that union from the first feature.
- Save the results.
