Join Gordon Luckett for an in-depth discussion in this video Overlaying two vector layers, part of Learning QGIS (2015).
- There are many types of overlay analysis,…including intersection or union,…which graphically combine or join vector based layers.…Within QGIS there are many ways to perform…geo-spacial analysis.…In this case, we will overlay buildings with parcels…so that the zoning attributes of the parcels…will be transferred over to the buildings.…Let's add buildings and parcels to our current session.…Let's add the parcel shape, and the building shape…to our current map.…If you pick on parcels, and click on Attributes,…you can see that there's a lot of columns…and we have Zoning, and Zoning one Description.…
We want to transfer this over to the buildings.…Let's look at the columns inside of buildings.…Inside of buildings if we open up the Attribute table,…we see there's only a half a dozen or so columns.…There's no zoning designation or zoning description.…What we want to do is pull that from parcels…into buildings, based on where the building sits…over top of the parcel.…So therefore if I zoom in…and I look at this particular parcel right here,…
