Hello, I have been trying to convert this raster data using QGIS's Polygonize function: https://daac.ornl.gov/VEGETATION/guides/Decadal_LULC_India.html
The converted geopackage is returning many geometries with negative areas. So much so that the data is highly inaccurate, and some categories are having negative areas with x^10 sq. meters in magnitude. The features basically resemble the ones I found in this stack overflow answer: https://gis.stackexchange.com/a/243707/161470 , where the holes are located outside the geometry and are larger than the geometry itself. How do I troubleshoot this? Is this a bug with QGIS? I'm using QGIS 3.14 LTS.
