Bug: the create polygon tool cannot be rerun twice

[jrutyna]

Clicking the “Create Polygons” button in the “Create W2 Segment Polygon” interface a second time will throw an error. A temporary work-around is to manually delete the newly created temporary layers (Segments, Transects, and Centerline) before clicking the “Create Polygons” button a second time. There is code in the create_poly.py file starting at line 16 to remove these files when the button is pressed... not sure what the issue is...

Hello sir ,could you tell me how to correctly install the Q-gis plug-in into Q-gis. Does this plug-in also need to rely on DEM data to construct the bth file? Looking forward to your reply，thanks

[jrutyna]

@mrliumouren, this wiki page should answer your questions. Also, we have just started another project to improve on this plugin...please see the rest of the issues to see our intended path forward.

Thank you very much, sorry I only saw the home page of the wiki page and didn't notice the table of contents.

I also took a while to notice that table of contents on the Wiki. Let's update the Wiki landing page to include links to those other sections (or to point out the table of contents on the right).

@mrliumouren & @aufdenkampe, the wiki has been updated to indicate the location of the table of contents.

I think it would be more eye-catching to put other directories under the home directory, rather than in the same directory as home. This is just my personal suggestion. BTW, As a beginner, besides the manual, where can I get started with the operation of this model software more quickly? Like videos or something else. @jrutyna & @aufdenkampe .I would be very grateful if you could give me some advice on how to learn this model.

@mrliumouren, the wiki page referenced above should be enough to get the plugin set up and functioning. @irishrose0312 was recently able to get the plugin working in QGIS without any prior experience with CE-QUAL-W2, QGIS, or python. Again, please carefully read over the wiki page. Unfortunately, at this time, the wiki is the only documentation/tech support that we can offer. Our current budget is to address the existing issues.

@mrliumouren, you might find some helpful links if you do a search on the term "CE-QUAL-W2 workshop". One result from EPA: Introduction to CE-QUAL-W2 (YouTube).

@jrutyna @tslawecki thanks for your reply. Thank you very much for the video link you provided. Some videos about ce-qual-w2 on YouTube are set to private, so it is a bit difficult to find these videos. I have watched 2 issues of the project "CE-QUAL-W2 workshop" on github. They explain ce-qual-w2 more from a theoretical perspective, and there may be fewer practical steps. Thank you very much again for your help.
