Changelog

lidRmetrics 0.1.4

• fixed a bug in metrics_lefsky() that caused empty voxels to be classified as “Oligophotic” (#25)

lidRmetrics 0.1.3

• fixed a bug in metrics_set3()

lidRmetrics 0.1.2

Breaking changes

• changes in metrics_set2() and metrics_set3(). metrics_set2() now consists of all metrics that are calculated based on the Z, ReturnNumber and NumberOfReturn attributes. Metrics that require more time consuming computations in 3D space (metrics_rumple(), metrics_voxels()) as well as less common metrics are now moved to metrics_set3().

Enhancements

• added benchmarking results in readme.md

Fixes

• Fixed issue with metrics_echo2() that caused function fail when the KeepReturns was NULL (default value). Function’s new default value of KeepReturns is set to c(1,2,3,4) (#19).
• Fixed issue in metrics_texture(). Updated to match the most recent changes in the ForestTool package (#20).

lidRmetrics 0.1.1

Changes in version 0.1.1

New features

1. New function metrics_echo()
2. New function metrics_echo2()
3. A new vignette demonstrating how to create custom metric sets.
4. General improvements and bug fixes.
5. Each metrics_*() function gained a convenient shortcut version: .metrics_*

Enhancements

1. Variance (var) is now calculated by metrics_basic(). This may potentially break some existing processing routines.
2. Added several checks for user-provided input. Error messages should now be a bit more informative.

Fixes

• Examples are now provided for all functions.
• All examples were updated - lidR::grid_metrics() function replaced with lidR::pixel_metrics()
• Fixed issue with metrics_voxels() failing when the zmin parameter was used #3 and #11
• Fixed issue with warnings being generated when using metrics_basic #12
• Fixed issue with warnings being generated when using metrics_dispersion #13
• VCI calculations were incorrect. VCI now requires zmax parameter to be calculated.
