Accuracy Assessment produces problem #55

Closed jcf7140 closed 3 years ago

Hi there

I've tried the accuracy assessment for the first time today, but unfortunately it's not working. I followed the steps as set out in an online tutorial and made sure that both my raster and reference vector file is in the correct format. However, everytime I run the process, QGIS gives me the following error message and stops processing:

2019-03-11T15:02:59 WARNING Traceback (most recent call last): File "C:/Users/Jcf.7140/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\maininterface\accuracy.py", line 48, in calculateErrorMatrix self.errorMatrix(self.clssfctnNm, cfg.referenceLayer) File "C:/Users/Jcf.7140/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\maininterface\accuracy.py", line 154, in errorMatrix cfg.utls.vectorToRaster(fd, str(l.source()), classification, str(tRC)) File "C:/Users/Jcf.7140/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\core\utils.py", line 5984, in vectorToRaster referenceRasterName = cfg.bandSetsList[cfg.bndSetNumber][3][0] IndexError: list index out of range

Any assistance will be much appreciated!!

Hello, it seems an issue related to the vector. Please check that the coordinate reference system is the same for both data. Also, please follow these steps https://semiautomaticclassificationmanual.readthedocs.io/en/latest/faq.html#how-can-i-report-an-error

Hi Luca Thanks for the quick feedback. I've checked the CRS of both datasets and they're identical. I have also followed the steps on the link you provided and have the log file and error message ready - just waiting to be accepted onto you Fb group.

Thank you for providing one of the best plugins I've ever used in QGIS!

I'm closing this because of the new version 7. If you still get the same issue, please reopen it
