    • Division/Order - Tree Dominant (dominant life form)
    • Class - Woodland (spacing & height of dominant form)
    • Subclass - Evergreen Woodland (morphological & phenological similarity)
    • Group - Temperate Evergreen Needle-leaved (climate, latitude, growth form, leaf form)
    • Formation - Evergreen Needle-leaved Woodland with Rounded Crowns (mappable units)
  • B. FLORISTICS
    • Alliance (Cover Type) - Douglas Fir Woodland (dominant species)
    • Association (Community) - Douglas Fir / Snowberry Woodland (subdominant or associated species)

Data Issues

Present Status
  • Approximately 165 projects in process
  • 30 Parks started (1994-2000)
  • 29 Park projects started in 2001
  • 11 Park projects started 2002-2004
  • 2005 completed 11 more parks, continued 73 ongoing projects, and initiated 24 new starts
  • 39 Parks completed for web access
  • more completed soon; 62 AA stage completed
    • 62 FY 05; 80 FY 06; 116 FY 07; 146 FY 08
  • Alaska: 6 parks complete in 2003; 3 in 2004; 3 new ongoing in 2005; 4 more completed 2006-7; 3 more starts 2006-08
  • USGS partnering on funding, 3 methods, archiving contract, collaborative fire and fuels datasets, variability analysis and surface model developments

new models

New Models

New Models
  • “New/other” technologies
    • High Resolution Remote Sensing
    • eCognition segmentation
    • Laser Rangefinder Remote GPS positioning
  • Sister Bureau hybrid techniques
    • FWS Lower cost Vegetation Map “Light”
    • Savings from reduced field collection
    • BLM / USFS vegetation cross walks ROMO/GRSA
  • Field Vegetation Guides – VOYA
  • Network strategy / plans PACN & MOJN
multiresolution segmentation

Hybrid Techniques

Multiresolution Segmentation
  • Levels 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 summary of current efforts

Hybrid Techniques

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)
national park environs data successes

Summary & Partnerships 1

National Park / Environs – data successes
  • Consider areas of interest for small park methodology
  • Evaluate sparse vegetation sampling need and plot sizes
  • Fire and fuels protocols may integrate fuels stratification in sample design
  • Develop fuel model polygons from NVCS vegetation polygons / photos
  • Other fire and monitoring program data needs…
nps environs fire data summary

Summary & Partnerships 2

NPS / Environs – fire data summary
  • Park Fire Management team field verify / photo reference fuel model types
  • Evaluate LANDFIRE data potential; AA of EVT layers
  • How map classes improve Landfire and other models
  • Research partnering for a hybrid approach, as needed
    • Fire fuel classes / types
    • Fuel loadings (1/10/100 hr…)
    • Fire Regime Condition Class
    • LANDFIRE update as appropriate and as supported by partnership
summary of efforts in 2007 8

Summary & Partnerships 3

Summary of Efforts in 2007-8
  • Fund $4M ongoing projects in 25+ networks
  • Provide technical support and planning assistance to parks, networks, and regions
  • Prioritize candidate projects with VMP team
  • Facilitate new planning based on park and network leveraged funding using hybrid innovations; new starts in ~ 2011-12
  • Action plan for creation / migration of NPS data, and USGS-NPS archiving
  • Develop and serve planning templates on the web and a PLOTS 3.0 database update
suggestions to benthic efforts

Benthic Partnerships 1

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
suggestions to benthic efforts1

Benthic Partnerships 2

Suggestions to Benthic Efforts
  • Learn the USGS business model and facilitate joint papers on standards innovations
  • Regional Executive partnership on Green Book budget development, and USGS-NPS archiving
  • Develop and serve planning templates on the web and a draft 1.0 (geo?) database container
