    • Watershed Dashboard &High-Resolution ImageryMarch 5, 2012 Theresa Menard Stephanie Tom GIS Specialist Info Manager
    • What does TNC do?
    • CONSERVE LANDS AND WATERSON WHICH ALL LIFE DEPENDS
    • What are the threats?
    • Fence construction & animal controlWeed Control
    • Forest degradation Erosion & Runoff into Ocean
    • Where Do We Work?The Nature Conservancy Preserves 40,000 acres
    • Watershed Partnerships
    • Where are we going?
    • 10-yr Goal: To double protected area
    • How do we scale up our efforts?Aerial Weed Mapping Aerial Weed Control Watershed Dashboard Remote Cameras Remote Trapping
    • Conservation info in the hands of a few in different locations  Imagery  Weed locations, biodiversity, and land use (GIS)  Field camera pictures TNC TNC TNC Hawaii Molokai Maui TNC HonoluluTNC Kauai

    • Dashboard Challenges • Getting data from areas lacking cell signal. • Arcgis.com webmap limitations • Poor performance on IE • Upload max 2MB or 1,000 features • Doesn’t allow downloading of zipped shp files from webmap • Building community of users • Long-term hosting of website
    • The Imagery Story
    • Helicopter-basedAerial Weed Mapping
    • Australian Tree Fern Invasion
    • • Ultra-high resolution image- based mapping• Weed detection over large areas
    • Ikonos Imagery
    • Resource Mapping’s ImageryThis iswhat thenewimagery ofthat spotlooks like!
    • Very high resolution means…Scale: 1 to 300,000
    • Scale: 1 to 200,000
    • Scale: 1 to 100,000
    • Scale: 1 to 50,000
    • Scale: 1 to 10,000
    • Scale: 1 to 5,000
    • Scale: 1 to 1,000
    • Scale: 1 to 100
    • Image-based MonitoringBefore treatment After treatment
    • Huge Imagery ArchiveKauai: 34,000 images Maui: 32,000 imagesMolokai: 24,000 images Hawaii: 27,000 images
    • Imagery Challenges
    • Data Storage Problem 8 TB Used Network Space5432 Used Space (TB)10 1-2cm Other GIS Shared PC Imagery Data Docs Backups
    • How much more storage space will be required?2 cm resolution imagery 1 cm resolution imagery (2008 – 2010) (2012)
    • Internet Access Problem Image Services - May Crash Your Computerhttp://hbmpweb.pbrc.hawaii.edu/arcgis/services
    • Internet Access ProblemMapping Service: http://bit.ly/xzFvOd
    • Mosaic Dataset Problem
    • The New Bliss!
    • PAU
    • What’s next in conservation tech?  Weather cam  Fiberoptic fence monitoring system  Mobile data entry  Expanding cell signal into dead areas  Expanding GPS signal into deep valleys  Animal recognition software  Search and rescue dogs for navigating to weeds
