The inventory is always linked to an analysis area, and usually to a sample of the stands in this area. This if the stratification of the imported stand register was successful. Data from the stratification is here selected, first the sample stands (a.k.a. Treatment Units), then the corresponding sample plots (a.k.a. Reference Units).

  • Create the actual inventory

Actually, the inventory is predefined in a number of tables (found in the table-droplist). Most of the variables to be estimated ("measured") in field are mandatory, only a few are voluntary and hence possible to exclude. However, it is possible to define "new" variables, just make sure they are added to correct tables (following the logical order to be estimated in field). Finish this part by "Create Inventory Database".

  • Create the mobile database

The mobile database, created from the inventory database, is exported and imported in the field data collectors, assumed to be equipped with Windows Mobile as OS and SQL Server 2005 Compact Edition. The field inventory is described in IVent.

The setup concern several details (...) but mainly the variables to be estimated in the inventory. When this is decided, a template is exported to the data collector. Inventory data can then be imported in a running manner, added and checked for errors until completed. A complete inventory is finally exported and imported in the Heureka forest database.
