Feature Request - manual crown delineation #447

Closed Saadi4469 closed 3 years ago

Saadi4469 commented 3 years ago

Hello,

I would like to request a feature similar to find_treesmanual mode to have a manual mode for crown delineation. Yes, the current 3 algorithms work quite well, but sometimes there are some problems with some handful of the crowns. Hence, I would like to request a feature that not only allows manual selection and deletion of crown/hull polygons, and then also be able to delineate a correct approximation of that particular species crown by manually creating a polygon similar to the process in ArcGIS/QGIS.

Thank you,

Sorry it is not possible. With rgl we can only select rectangular regions of interest. With mapedit you can draw polygons on top of raster. It may fit your needs.
