I have several shapefiles which contain buildings built in different periods from 1948 to 2013. My question is how could I see which buildings for example in were built 1948 but are missing in later periods? Is there a tool in QGIS, or something for automatization? I would think clicking and unclicking layers wouldn't be the best and most efficient option.
Data: shapefiles, aerial imagery (1948, 1971, 1981, 2009, 2013)
I use one shapefile that has a field with the dates of when the buildings were built, such as: before 1948, 1970, between 1971-1981, 1981-2009, built after 2009. They all share the same number of fields and data, the things which differs are the attributes of course. But I'm not sure about this option.
Initially, I was thinking of separating the into 5 shapefiles so as to figure out an easier way to see the differences. As an example: shp 1948 contains (buildings built until 1948), 1971 (all until 1971 including data of previous shp), so on and so forth.
The thing is I used aerial imagery from those years to see whether those buildings still exist or not, so as to update each shapefile correspondingly. Partially done while the data was under a single shapefile, as some were missing.
