Lacreek National Wildlife Refuge Vegetation Mapping Project Vegatation Coverage

Geospatial_Data_Presentation_Form: map

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: n/a

Logical_Consistency_Report: None.

Completeness_Report:

All points required for an accuracy assessment were included in the coverage. After the field work was performed, several points were dropped from the coverage because the points were in-accessible during the field work.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report: Positions acquired from GPS units.

Lineage:

Process_Step:

Process_Description:

Points were established using a stratified random sampling method (portions of the methodology were derived from the USGS/NPS Vegetation Mapping Program's Accuracy Assessment Procedures). Point coverage created using an in-house developed AML using certain criteria for point placement. During the field work, vegetation data at each point was recorded using standard NVCS Plot Point collection form.
