Description:

Abstract:

A plant community and locally tailored mapping classification had been created to map and describe functions of the wetlands on the Kenai Lowlands west of the Kenai National Wildlife Refuge, Alaska (the project area). The classification has been used to map wetlands in the project area. This file extends the project area to include Seward. The map is served via Environmental Research System's Internet Map Server software, so that all that is required of an potential user is access to the World Wide Web and a current web browser. The wetland polygons will be served on the map along with high resolution satellite imagery and parcel lines. The wetland polygons are linked to a web of descriptive documents incorporating plant, soils and hydrology data, and photographs.

Purpose:

To give landowners, prospective land owners, managers and other interested parties access to a locally relevant wetland map so they can make informed decisions.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

After entry, attribute values were printed and compared to raw values recorded on datasheets. Errors were corrected.

Logical_Consistency_Report:

Logically consistent: polygon geometry clean, "Area" field indicates no sliver polygons. No formal report generated.

Completeness_Report:

Exact wetland boundaries are perhaps impossible to delineate. The definition of a wetland can change, and is somewhat open to interpretation. This file represents an attempt to delineate every polygon that could be considered a wetland using the criteria outlined in the 1987 Army Corps Delineation Manual (Environmental Laboratory. (1987). "Corps of Engineers Wetland Delineation Manual", Technical Report Y-87-1, US Army Engineer Waterways Experiment Station. Vicksburg, MS). To generate the file, stereo paired aerial photos and relatively quick field visits, along with National Wetland Inventory maps and data were used. Non-jurisdictional wetlands are also included, such as Depressions.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Wetland boundaries are not precise. The file was generated using 1:25,000 stereo paired aerial photographs, linework was transferred, using a plastic pencil, to frosted mylar overlain on quarter quad film positives.
