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. Field collected data can continuously be imported as the inventory proceeds.
- Export - import in the forest database
Data is checked for errors, corrected if neccessary, and when the inventory of plots and stands is completed, set as "Checked". Data is finally transferred from the inventory database to the forest database, ready to be analyzed with PlanWise.
