5 NPS vegetation mapping projects BackgroundNational ProgramDiffers from otherNPS vegetation mapping projects270 park units (full park coverage)minute USGS quadranglesNational scopeParticipation of multiple agenciesConsistency in detail and accuracy between parksProduces digital products available on WWWCoordination at multiple levels
6 Standards NPS management policies, standards & guidelines BackgroundStandardsNPS management policies, standards & guidelinesFederal Geographic Data Committee standardsmetadata, transfer, classification etc.Nationally consistent, hierarchical, classification schemeNational Map Accuracy StandardsThematic accuracy >80% per classScale of 1:24,000Minimum mapping unit of 0.5 hectare
7 Major Steps for each Park Data IssuesMajor Steps for each ParkScoping meetingData reviewData acquisitionField samplingClassification characterizationPhoto interpretation, mapping and automationAccuracy assessmentFinal product reviewThese are the basic steps that are required for each park unitData review - there are usually a lot of data avalaible for each unit, and it takes time and coordination to bring them togetherThe field sampling should ideally take place when the photo interpreters are doing their field work, so there can be coordination between what the ecologists classifiy and what the intepreters identifyThe accuracy assessment should ideally be done when the mapping is complete so we can design a stratified random sample, but for efficiency’s sake, we often do accuracy assessment at the same time as the original field sampling
8 Products from the Program Data IssuesProducts from the ProgramAerial photography/ imagery (hardcopy / digital, some new DOQQs)Field data (hardcopy and database)Classification report (Description and Key)Photo interp report (Description and Key)Accuracy reportVegetation map data (digital coverage)All appropriate metadata
9 FGDC National Vegetation Classification System 2006 Data IssuesFGDC National Vegetation Classification System 2006A. PHYSIOGNOMYDivision/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. FLORISTICSAlliance (Cover Type) - Douglas Fir Woodland (dominant species)Association (Community) - Douglas Fir / Snowberry Woodland (subdominant or associated species)The system is hierarchical which allows it to be used for many different levels of analysis and study - from National to regional to each Park to each site.It is also standard - so we do not have to reinvent the wheel for each park, although a lot of development work has to be done for each park.
11 Present Status Data Issues Approximately 165 projects in process 30 Parks started ( )29 Park projects started in 200111 Park projects started2005 completed 11 more parks, continued 73 ongoing projects, and initiated 24 new starts39 Parks completed for web accessmore completed soon; 62 AA stage completed62 FY 05; 80 FY 06; 116 FY 07; 146 FY 08Alaska: 6 parks complete in 2003; 3 in 2004; 3 new ongoing in 2005; 4 more completed ; 3 more startsUSGS partnering on funding, 3 methods, archiving contract, collaborative fire and fuels datasets, variability analysis and surface model developments
19 USGS-USFWS Vegetation Mapping Projects Program StatusUSGS-USFWS Vegetation Mapping ProjectsOuray NWRLacreek NWRWe are just getting started with FWS. We are working with Region 6 out of Denver to start 2 refuges – Ouray and Lacreek. There are close to 150 refuges in Region 6 and over 500 refuges nationwide covering 92 million acres of land and water.Region 6 is taking the lead for the Agency on this effort – we have really not had national support to date, but I think with the completion of these two projects will really show the agency the value of these products – consistent, useful for practical on-the-ground management, yet scientifically sound.

21 Cabrillo is working with State, Corps, and US Navy to figure out jurisdiction of the park acres.
22 Multiresolution Segmentation Hybrid TechniquesMultiresolution 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.
23 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 GRKO, LIBI, KNRI, FOUN)Verify eCog gradient test against completed AA (ROMO)Machine classification and PI field sample verification (LAVO)
