| Feb 27, 2022 at 4:39 | comment | added | ShyGiantRat | I'm now having exactly the same problem. I'm also using Python(rasterstats) and QGIS together. I think it depends on how it handles pixels that are on the border of the polygons. This link might be helpful for understanding how QGIS zonal statistics works. gis.stackexchange.com/questions/276794/… | |
| Sep 10, 2021 at 11:56 | comment | added | eigenvector | Yes: without all_touched=True many numbers are missing (probably those polygons that do not fully encompass a raster pixel?) and the numbers that are not missing are the same as in QGIS Zonal statistics. Does that suggest that QGIS Zonal statistics uses "all_touched" true whenever the polygon is smaller that the raster pixel and leaves the option away when it is bigger? | |

Have you tried without all_touched=True
