Feature request #19403
identify interpolate between measures
|Pull Request or Patch supplied:||Yes||Resolution:|
|Easy fix?:||No||Copied to github as #:||27231|
If a line has geometry with M values, Identify currently shows 'closest vertex M' as a derived value in the Identify panel. It should however also be showing the interpolated measure, which it no longer does. See https://github.com/blazek/lrs/issues/24#issuecomment-404443408
Resurrect display of interpolated z/m in identify results, and
add closest point x/y (closest point on geometry)

- Tracker changed from Bug report to Feature request
- Subject changed from identify no longer interpolates between measures to identify interpolate between measures
Qgis has never interpolated z/m for the identify tool - maybe this was a plugin implementing it.
#2 Updated by Radim Blazek about 2 years ago
It was working. I implemented interpolated measure in identify tool here: https://github.com/qgis/QGIS/commit/5c6e794b2d57e as replacement of that functionality in LRS plugin, when M became supported by QGIS core in 3.x. Note "Closest point M" and QgsGeometryUtils::closestPointMeasure() in the commit.
