Part 4: Working with Site Unit Tables
Verifying and Checking Data for Errors
Repairing and Optimizing Vegetation Entries
When you select this tab, you will start by choosing an attached Project and a Site Unit list.
You can then choose any of the following options to repair errors.
Repair Options
What Happens
Fix One-To-ManyRelationship Errors
VPro fixes any relationship errors between the six main data tables in a Project.
You can check for these errors by selecting the Other Tests tab and run Check
One-to-many Relationships.
Optimize Vegetation
VPro places all of the VTAB records into a single row. At times, data imported
from VTAB may have repeated species entries for several different layers (e.g.
Pinucon may have an entry and cover value for A3 and B1 layers).
Vegetation Code
Check
VPro checks all of the vegetation codes listed in a Project against the current
Provincial list of vegetation names. This procedure is very similar to performing

a spell-check in MS Word . VPro will prompt you for each vegetation name
that does not match the provincial list. VPro also recognizes synonyms, old
code names that have been updated. You can change all occurrences of a code
by selecting Change All.
Audit Trail
The audit trail is a function that keeps track of changes to plot records over time and indicates:
•
Initial codes,
•
Data of change, and
•
New codes.
To perform an audit trail, you can do one of the following:
•
Select the Audit tab on the 4-page data entry form to display all of the changes made
to a single plot, or
•
Select the Audit button on the 2-page data entry form to display a table with all audit
records.
