Standards

Background

Standards

  • NPS management policies, standards & guidelines

  • Federal Geographic Data Committee standards

    • metadata, transfer, classification etc.

  • Nationally consistent, hierarchical, classification scheme

  • National Map Accuracy Standards

  • Thematic accuracy >80% per class

  • Scale of 1:24,000

  • Minimum mapping unit of 0.5 hectare

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

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
