I am trying to find a tool in QGIS that does the same function as Region group in ArcGIS.
What I am trying to do is to identify uniquely each patch of a raster that has a certain value (e.g "Value" =1) using neighbouring cells.
From the region group docs:
For each cell in the output, the identity of the connected region to which that cell belongs is recorded. A unique number is assigned to each region.
