Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The classification of vegetation for this accuracy assessment was accomplished through the use of a vegetation key. Field assessors, at times, felt as if they did not have a "good" option when using the key. These points are discussed in detail in the final report.

Logical_Consistency_Report: Points were created from GPS data recorded in the field.

Completeness_Report:

These points represent the target accuracy assessment points actually visited in the field.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Location information was taken with a GPS and differentially corrected. No quantitative report of accuracy is available, but standard deviations calculated for each position were used to filter locations before use in the accuracy assessment.

Lineage:

Process_Step:

Process_Description:

Points were selected at random within each vegetation association on Fire Island. These points were then broken up into routes which covered a specific region of Fire Island. Assessors used field keys prepared by NatureServe to classify polygons in which accuracy assessment targets were found. They also included notes as to the confidence they had in their classification and the spatial accuracy of their point. All information was recorded on a GPS unit which also recorded a positon for the interpreted location.

Detailed_Description:

Entity_Type:

Entity_Type_Label: fiis_aa.pat

Entity_Type_Definition:

Accuracy Assessment Point Dataset information for the entire length of Fire Island and the William Floyd Estate. The accuracy assessment mission was conducted in September of 2001. The data and location of each point was collected with a GPS unit. We used guidelines from The Nature Conservancy (1994) to determine the number of accuracy assessment points needed for Fire Island.
