<p class="MsoNormal"><span lang="EN-GB">Dear all,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Since there is a lot of expertise on the ML in hydrology and LiDAR, I was wondering if someone is aware of a GRASS approach for identifying and carving Culverts (as well as removing bridges) in LiDAR DEMs.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Here some non-GRASS examples of what has been done earlier:<o:p></o:p></span></p>
<p class="MsoNormal"><a href="https://www.tandfonline.com/doi/full/10.1080/13658816.2018.1530353"><span lang="EN-GB">https://www.tandfonline.com/doi/full/10.1080/13658816.2018.1530353</span></a><span lang="EN-GB"><o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I do have an idea of how to solve this in GRASS (also conceptually a bit different from the approaches above), with a rather simple / simplistic prove of concept based on geomorphometrics.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Yet, maybe someone around has a good procedure ready? Is there collaboration potential / interest?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Cheers<o:p></o:p></span></p>
