The inventory is always linked to an analysis area*, and usually to a sample of the stands in this area (possibly in different domains). This if the "stratification" of the imported stand register was successful. Data from the predeeding sample design is here selected, first the sample stands (a.k.a. the Treatment Units), then the corresponding sample plots (a.k.a. the Reference Units).
*) Not necessarily linked to a geo-referenced area (i.e. a forest map), though such is usually available and already imported. Theoretical sample plot-centre coordinates (x- and y-values) are expected to be derived externally, more about this in "Sample design".
- Import sample stands and corresponding sample plots (1)
...Auto..., the other..?
- 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 to and imported in the field data collectors, assumed to be equipped with Windows Mobile as OS and SQL Server Compact Edition. The field inventory is described in User's guide to Ivent. 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.
