I have QGIS 3.18 Zurich with GRASS 7.8.5 installed on my 64bit Windows machine. I have digitized 1600+ polygon boundaries that now have sliver polygons, gaps, and overlaps which I've confirmed via the Topology Checker Plugin.
Data are in EPSG 32629 (WGS84 UTM 29N). I've created a key variable FID which was calc'd as @row_number. I am attempting to run v.clean on this data in QGIS with the following parameters:
Input Feature Type = area Cleaning tools = bpol, rmarea, rmline, rmsa, rmdupl, rmdac Thresholds = 5,5,5,5,5,5 (this is 5m; I have also tried no thresholds) Output type = auto Combine tools with recommended follow-up tools = yes V.in.ogr snap tolerance = 0.05 (5cm) v.in.ogr min area = 10.0 (10 sqm, smallest polygon is 11sqm)
However I keep getting blank "Error" and "Cleaned" out puts and receive the following errors in the log:
WARNING: Number of centroids exceeds number of areas: 1619 > 1448 WARNING: Number of incorrect boundaries: 202 WARNING: Number of centroids outside area: 171 ERROR: Key column <> not found WARNING: Unable to determine input map's vector feature type(s). WARNING: No attribute table found -> using only category numbers as attributes WARNING: Output layer is empty, no features written
What am I doing wrong? Data are here: https://drive.google.com/file/d/1lYIVkftS_XLRF1CQcNsjNI_s5ToegC8w/view?usp=sharing
