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
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
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)
