As in the picture below, I am trying to merge the grids that are touching one another into a single polygon. I tried using the dissolve configuration on QGIS but it produced either 1) a vector polygon with just single observation or 2) replicates the exact grid vector with same number of observation.
From what I can imagine in the image below, the procedure should produce about 7 to 8 larger polygons and a few smaller ones.
In the past I did something similar but by using the GRASS Neighbor configuration and then polygonize the produced raster file but somehow I am unable to replicate the same thing with this exercise.
The purple grid each has a unique id and also contains the building (brown) coverage percentage for each grid.
The suggestions in response to my question seem to produce what I wanted. However, I do notice that there are some polygons that should be a single big polygon but instead are separated into smaller parts even though they are directly touching one another as shown below (lime green polygons).
Is there any way to fix this?
