BACKWARD INCOMPABILITY WARNING
Although this can cause backward compability issues, I felt it was necessary to rename the following functions:
vwf (stands for Variable Window Filter)
mcws (stands for Marker-Controlled Watershed Segmentation)
Reasons for the changes are:
In addition, I’ve made the following changes to
maxWinDiameterargument to 99. Note that this value sets the maximum width in cells of the widest allowable window diameter. As explained in the documentation, this argument is to prevent the function from gobbling up too much memory, and can be disabled by setting to NULL.
TileManagerpackage. Although I had put considerable effort into adding this feature initially, I’ve realized that A) no one was using it, B) it is preferable for the user to manage tiles him or herself instead of having them managed “under the hood” by the
vwffunction. Let me know if you thought this feature was useful and perhaps I can write a vignette suggesting preferable ways to manage a tiled CHM.
Modified ‘SegmentCrowns’ function so that it can produce tree crowns in polygon format. The function will also calculate crown area, and filter out crowns that are not associated with a treetop point location.
Changed name of ‘TreeTopSummary’ function to ‘SpatialStatistics’. This reflects its new functionality, which allows crown maps to be inputted as well as treetop locations.
