Some additional settings are done during the import, e.g. the type of data is usually "Strata", meaning that only a sample of the stands (the treatment units) in the current analysis area have been in-field inventoried by systematic plot sampling (hence, these sample stands represents a larger area than the actual). Data type "Complete" means that all stands in the analysis area have plot data, obtained either by a complete field inventory or (more likely) by the "Forking method" - an imputation technique recycling FMPP-plots and simulating plot data in non-inventoried stands.

+It is possible to import data from the Forest Management Planning Package (sv: Indelningspaketet, IPAK). Three basic files
+are then needed:
+*PLANT.DAT
+*PTFI.DAT
+*YTOR.DAT
+Some additional settings are done during the import, e.g. the type of data is usually "Strata", meaning that only a sample of the stands (the treatment units) in the current analysis area have been in-field inventoried by systematic plot sampling (hence, these sample stands represents a larger area than the actual). Data type "Complete" means that all stands in the analysis area have plot data, obtained either by a complete field inventory or by the "Forking method" - an imputation technique recycling FMPP-plots and simulating plot data in non-inventoried stands using information in the existing stand register. Also, the county of the current analysis area is set, as if tree age has been measured for the sample trees or estimated as a mean age at the stand-level. Be aware if the tree species codes (both for trees and saplings) used in the FMPP-inventory differs from those in the Heureka-system.
 In menu "External data" > "Import FMPP data...":
-#"Browse..." to the catalogue with the basic files.
+#"Browse..." to the catalogue on your computer holding the four basic files.
-#Some knowledge about the inventory is necessary, e.g. where it was performed (in what county), when (what year of inventory)  and how (e.g. what tree species codes were used).
+#Set the additional information necessary.
+#Link to an existing analysis area or create a new (namned in "Description").
+#Press "Ok".
-The basic files are checked for errors in the FMPP. Additional variables could have been estimated in the field inventory (maybe variables useful in analyses with the Heureka system). The aware user might see that AVDDEL.DAT, usually regarded as one of the four basic files in the FMPP (obtained in import of inventory data), has been replaced by RESFI.DAT. This implies that FMPP's "inital state generator" (TILLST.EXE) has been run.

 *'''Note'''
-:Be careful when using imputed plot data/simulated single tree-data based on a stand register of uncertain quality. Any systematic errors here will comply and might even grow with the prognoses, with negative impact on the planning result's reliability. In strategic planning, this carefulness should increase with the length of the planning horizon.
