Updating and Tracking Wetlands

Developing a System to Track Wetland

Changes Over Time Using ArcSDE


Why is DU Interested in Updating

and Tracking Wetlands?

Habitat Modeling

Restoration Planning

580529


Wetland Functional Assessment

Paw Paw Watershed, Michigan (MI DEQ)


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


How do you accomplish it?

How do you keep

track of this

wetland if you

delete it from the

current inventory?



What do you do

with this one?



How about this

one?


Spatially Combine Two Dates

1978 NWI 1998 NWI Combined 78-98


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


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.

Status will allow us

to determine if the

wetland is “active”

(currently exists) or

“inactive” (been

converted).

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

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

Determines number of wetlands to select

Randomly selects wetlands

Adds field verified wetlands from PI process

Create personal Geodatabase of selections


Produce Field Maps


Add Field Data to Geodatabase
