Show raster row/column of clicked point in identify results #8764
Conversation
|
Interesting remark. The identify tool description is quite vector centered right now despite it can be used also with raster, mesh or point cloud. We could move/create a section for results dialog (and format specifics) to each data type chapter, leaving the common how-to parts and options description in the general tools chapter. Just a rough idea (unfortunately not resulting in a single line PR 😄) and I'm open to all options... |

I have added the "Introduction to Raster Data" chapter and provided details about the Identify tool. I will create new PRs for point cloud, mesh, and vector data. |

It is weird that the build passes with two identical topmost underlines (i.e. page title) in the same file. Anyway the generated HTML is worth a look and you might need to review the sectioning here. E.g. we usually have a table of content displayed just below the page title; here it might be under raster properties section, far below in the page.

but if this is the top title I don't know if "introduction" is the most suitable for the addressed topics. Introduction is just for the first two paragraphs. that said, I have no suggestion.

I agree... Is it possible to retain the text but remove the sectioning (title), if that makes sense? I was considering removing it entirely...

Assuming I understood correctly, I'd find weirder to have a new chapter/page that starts with no title.

Reading my previous comment it was probably not clear but the TOC should be moved up, under the top title, to catch all sections of the page. and not stay in the middle of the page.
[Backport release_3.34] Show raster row/column of clicked point in identify results (backports #8764)
Fixes #8500
I believe that such 'small details' should be mentioned in the 'Working with Raster' chapter, but I'm not sure how to incorporate them into that chapter. I would like to hear suggestions and opinions on this.
