Multiresolution SegmentationLevels can be used to compare results of segmentation based on different scale parameters and homogeneity criterion.Layers can be weighted. Weights determine to which degree the information is used during the process of object generation.
Hybrid Techniques
USGS-NPS Vegetation Mapping ProgramThe National Park Service
Hybrid techniques – summary of current efforts
Mixed imagery and Sister Bureau eCog segmentation and skeleton polygon sampling (GRSA)PI / eCog linework and model verification (MEVE) / ground reference; add attributes (field & automation savings)Classical accuracy assessment (AA) or small park methodology (census of MMU @ GRKO, LIBI, KNRI, FOUN)Verify eCog gradient test against completed AA (ROMO)Machine classification and PI field sample verification (LAVO)
Hybrid Techniques

Suggestions to Benthic Efforts
Stabilize the mapping standard, even a draft for NPS Marine Parks
Work the 3 prototype parks, networks, and regional candidate areas
Evaluate candidate projects against the draft standard
Grow / update from the prototypes
