Is it possible to split up the individual values of a raster to make each value become a different layer?

I am aiming to create an animated map with TimeManager. However, the data I need for each layer of the animated map is within one raster.

The raster is split into 16 values from 2000-2016. Is there a way to take out each value to create a new layer?

Here is a picture of the raster for more clarity.

  • Those this raster have several bands or has each pixel a value which corresponds to the year?

1 Answer 1


For TimeManager, you need a vector, i think :

Solution 1 : vectorisation

If your raster is in integer format :

  • use the polygonize tool
  • animate on your value field.


To answer your title question :

Solution 2 : raster reclassification

  • Use a Raster Calculator expression ("MyRaster@1 = 1", then "MyRaster@1 = 2",...)to get a reclassified raster for each year (every pixel that answer the logicial condition is equal to 1 and the others are equal to 0 or are null)
  • Create 16 new raster with that.
  • put it in display and color it with a 1 = color style

value = 1

Solution 3 : duplicate and style

  • just duplicate your raster 16 times (right click/duplicate)
  • on the first layer (set all colors to transparent (0% opacity) except the year color
  • copy paste style and just change color 2 to full opacity and 1 to 0%.
  • do the same for all layers


  • @amd I added another solution if you need vector to animate :)
