[Qgis-user] QGIS 3.16 Training Manual - Module 8.2.1 - Intersect features

Tue Jan 12 10:18:07 PST 2021

The tutorial needs a lot of love to get it to the same level as the User Guide 😊 I have a background in documentation but currently don’t have time to devote all the time that is required to update the text, screengrabs, URLs etc. I’ve encountered more issues today such as WMS and WFS URLs/hyperlinks no longer working and more but currently don’t have the time to go through any more tutorial pages.
I’ll do what I can when I can.
Could updating the tutorial be sponsored if deemed sufficiently important to update?

Regards,
Inna Nogeste

Sure!

Add a comment on github with @SrNetoChan to mention me.

Thanks for your help! The training manual needs some love, but most resources are directed to the user manual.

Hi Alexandre,
Thanks for your YouTube links, they help alot. I have made alot of notes to date as to what should be updated in the QGIS 3.16 Training Manual and will gradually add these to Git Hub using your YouTube instructions.
I’ll let you know when I’ve started so that you can perhaps check that I have done it correctly?

Inna Nogeste

Hello Inna,

If you want, I can help you make the change yourself :-)

Or, alternatively, check the following videos to see how you can do it

Hi Wanda,
 Looking at my notes for what wasn’t working for me in the Training Manual exercises, I see that I needed to make the following change in Step 6.2.8 using QGIS 3.16 :
“Need to set the processing option to Skip (Ignore) invalid geometry. Seemed to be a problem with the buildings_34s layer? Changed this option for both input and compare layers and it worked.”
 I hope this helps!

 I am getting the same error in the training module for lesson 6.2.9.  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.
 Thanks!

I’m working through the training manual and completed all the preceding modules and their output files.

to intersect my previous output files I get an error message when I run the Intersection tool that a feature in my Overlay layer ’has invalid geometry. 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%7C155d8d2f90fb42b20c6a08d8b660dd84%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637459874432941878%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=vwC8RM34ZvQEWlbwX5m%2Bvk%2FyV0KS9corUNkhB9Xu1YI%3D&reserved=0>
