Thanks to everyone for their replies. I haven’t used the Checck Validity tool and will do so. I understand that some of the material is outdated and is why I thought I’d go through it now that I have upgraded to 3.16 to see what updates might be required. I’ll post my suggested updates to GiHub when I’m finished.

Try both QGIS and GEOS methods. Topology Checker Plugin (that need to be installed under Plugins) also works well.

I have done the lesson twice thinking I had missed a step - but get to the same point of extracting the buildings and get the error message. I am using QGIS 3.1 with Windows 10 on my HP laptop.

Please fix the geometry or change the Processing setting to the “Ignore invalid input features” option.’ The overlay layer is a polygonized vector layer createdin a previous modeul in the training manual from a raster layer. The invalid geometry in the polygonized layer represents 1 individual cell in the original raster layer. Changing the Processing setting to ”Skip (Ignore) Features with Invalid Geometries” doesn’t help and outputs an empty layer. Has anyone else had problems with this module and the layer files created in previous modules? I’ve noted that the original SRTM_41_19.TIF exercise data is in EPSG 32733 and not EPSG 32734 as per the other exercise (vector) data and this causes issues when you get to Module 8. I’m currently documenting discrepancies that I’m finding in the training manual and am assuming that I can eventually add them to https://github.com/qgis/QGIS-Documentation/issues?q=is%3Aissue+is%3Aopen+label%3AEasy<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fqgis%2FQGIS-Documentation%2Fissues%3Fq%3Dis%253Aissue%2Bis%253Aopen%2Blabel%253AEasy&data=04%7C01%7C%7C22c9f81eed6b4cd0952508d8b3ed9d03%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637457180407295615%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=ixe8os5vcwSmDbUHvLeLHXBU6moIknfnSZT837kMl9U%3D&reserved=0> Regards, Inna Nogeste Skickades från E-post<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgo.microsoft.com%2Ffwlink%2F%3FLinkId%3D550986&data=04%7C01%7C%7C22c9f81eed6b4cd0952508d8b3ed9d03%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637457180407305609%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=J2h%2FklKWS4AyKNvKYSy4I5lkTenfw8SlAxK7524LK2w%3D&reserved=0> för Windows 10 _______________________________________________ Qgis-user mailing list [email protected]<mailto:[email protected]> List info: https://lists.osgeo.org/mailman/listinfo/qgis-user<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.osgeo.org%2Fmailman%2Flistinfo%2Fqgis-user&data=04%7C01%7C%7C22c9f81eed6b4cd0952508d8b3ed9d03%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637457180407305609%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=59UTT%2BcKp313XED%2BtJx%2BKQu4%2BQTxvYDWjm2ZXwjjjI0%3D&reserved=0> Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.osgeo.org%2Fmailman%2Flistinfo%2Fqgis-user&data=04%7C01%7C%7C22c9f81eed6b4cd0952508d8b3ed9d03%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637457180407315610%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=nQw8TL0scjRTDim2QC8B6Kpc6PQoYLPAWRMCUjKvdEQ%3D&reserved=0> _______________________________________________ Qgis-user mailing list [email protected]<mailto:[email protected]> List info: https://lists.osgeo.org/mailman/listinfo/qgis-user<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.osgeo.org%2Fmailman%2Flistinfo%2Fqgis-user&data=04%7C01%7C%7C22c9f81eed6b4cd0952508d8b3ed9d03%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637457180407315610%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=nQw8TL0scjRTDim2QC8B6Kpc6PQoYLPAWRMCUjKvdEQ%3D&reserved=0> Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.osgeo.org%2Fmailman%2Flistinfo%2Fqgis-user&data=04%7C01%7C%7C22c9f81eed6b4cd0952508d8b3ed9d03%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637457180407325598%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=rYB08awsD%2BNAfZAOusQ%2BC01iyDJn5IyRlCXZXwhNv1k%3D&reserved=0> _______________________________________________ Qgis-user mailing list [email protected]<mailto:[email protected]> List info: https://lists.osgeo.org/mailman/listinfo/qgis-user<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.osgeo.org%2Fmailman%2Flistinfo%2Fqgis-user&data=04%7C01%7C%7C22c9f81eed6b4cd0952508d8b3ed9d03%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637457180407335593%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=QSj7BqcJbf5QgZ9mwoOxsbtuxYO0HB07%2BNIM8rnUaG0%3D&reserved=0> Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.osgeo.org%2Fmailman%2Flistinfo%2Fqgis-user&data=04%7C01%7C%7C22c9f81eed6b4cd0952508d8b3ed9d03%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637457180407335593%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=QSj7BqcJbf5QgZ9mwoOxsbtuxYO0HB07%2BNIM8rnUaG0%3D&reserved=0>
