Updating and Tracking Wetlands
Why is DU Interested in Updating
and Tracking Wetlands?
Habitat Modeling
Restoration Planning

Updating and Tracking Wetlands
What Do We Want to Know?
Current Inventory of Wetlands
Track Wetland Changes Over Time
Agriculture Development
Inventory of Converted/Modified Wetlands
Type of Conversion
Recreation
Updating and Tracking Wetlands
How do you accomplish it?
How do you keep
track of this
wetland if you
delete it from the
current inventory?
Updating and Tracking Wetlands
Advantages:
Straight forward methodology
Separate layers for each date
Disadvantages:
Attributes get “messy” in the combined layer
More difficult to calculate and identify changes
Will get confusing when adding more then two dates
Multiple data layers to manage
Spatially Combine Two Dates
Updating and Tracking Wetlands
Database Keys and Attributes
Wetlands will be
tracked through a
NWI Key and Parent
Key. This will allow
us to go back to the
original wetland
shape and attribute.

ATTRIBUTE STRING (20)
HGM_CODE STRING (10)
QAQC_CODE STRING (9)
WETLAND_TYPE STRING (50)

INACTIVE_DATE STRING (15)
FIELD_VERIFIED STRING (1)

UPDATE_OPERATOR STRING (50)
UPDATE_DATE DATE
Updating and Tracking Wetlands
Status will allow us
to determine if the
wetland is “active”
(currently exists) or
“inactive” (been
converted).

Status becomes
inactive (I) if there
is a change in future
updates
A new polygon is created
that can be linked back
to original data through
the Parent_Key
If a polygon needs to be
split, both of the new polygons
can be linked back to the original
data through the Parent_Key

Updating and Tracking Wetlands
Advantages:
Can handle multiple updates and updates for small areas
Only one layer to manage
Easy to select historic and current wetlands
Easy to track individual wetlands
Disadvantages:
More complex methodology
Potential for more data entry errors
