- Attribute_Accuracy_Report:
- The accuracy of the final merged map for Shenandoah National Park
was assessed internally by sampling the final map with the training
sample locations and computing the percent plots correct (PPC) for
each class and the entire map. The overall PPC accuracy of the merged
map was 92%. Three of the association level classes were mapped with
a training set PPC lower than 80% accuracy. Comparison to external
accuracy assessment data collected in 2004 and 2005 showed per association
accuracy ranging from ~20% to 100%.
- Logical_Consistency_Report:
-
Data was developed from 3 sources: AVIRIS May 2000, AVIRIS July 2001, Landsat Multi-temporal imagery. Data source used for each pixel depended on availability of imagery and maximum probability of canonical linear discriminant analysis predicted class. Where Landsat data was used to fill in areas not imaged by the AVIRIS sensor, inconsistencies in the classification may result.

- Process_Description:
-
AVIRIS images were converted to reflectance, corrected for atmospheric effects, and referenced to UTM map coordinates.

-
- Process_Description: AVIRIS images corrected for cloud cover
- Process_Step:
-
- Process_Description:
-
Landsat images converted to reflectance, corrected for atmospheric effects, and georegistered.
- Process_Step:
-
- Process_Description:
-
Four reflectance spectra were extracted from the hyperspectral and multispectral images for an area surrounding each of 311 vegetation plot locations mapped in the field using GPS coordinates.
- Process_Step:
-
- Process_Description:
-
Canonical Linear Discriminant Analysis (CLDA) was used to derive a transformed set of image and topographic variables to discriminate between 34 vegetation association classes defined by Va. Natural Heritage.
- Process_Step:
-
- Process_Description:
-
Linear discriminant functions were mathematically transformed into probability values of class membership.
- Process_Step:
-
- Process_Description:
-
Probablility maps for each class were generalized using a focal mean operation to reduce erroneous pixels (speckle).
- Process_Step:
-
- Process_Description:
-
The final model mapped each pixel to the class with the highest probability.
