  "Description": "Provides a collection of routines for evaluating data from\nlarger forest management units, typically sample inventories,\nbut also stand-wise inventories. The idea is to support modern\nforest planning approaches and to be open by design to new data\nsources and evaluation methods. For the methodological\nbackground of forest inventories see Kangas and Maltamo (2006)\n\"Forest Inventory: Methodology and Applications\"\n<doi:10.1007/1-4020-4381-3>.",
