NRCS Briefing on Orthoimagery for Hawaii and the Pacific Basin
Hawaii and Pacific Basin Update<br />Hawaii Geographic Information Coordinating Council<br />August 13th, 2010<br />Tony Kimmet <br />USDA-NRCS-NCGC<br />
Why USDA for Orthoimagery ?<br /><ul><li>USDA supports GIS data acquisition and development in all geographical areas of the United States including Hawaii, Pacific Basin, Alaska, Puerto Rico and the US Virgin Islands.
USDA supports Special Emphasis Programs such as the Asian American and Pacific Islanders programs.
USDA employees over 600 employees in Hawaii and the Pacific Basin.
USDA uses progressive new technology for areas such as Orthoimagery acquisition.
As a member of NDOP and USDA Imagery Committees, I provide briefings 3-5 times a year on Hawaii and Pacific Basin Orthoimagery issues!</li></li></ul><li>

New Hawaii/Pacific Basin Acquisition Activity<br />
USDA-NRCS/FSA collected Orthoimagery for the Hawaii Islands in 1997-2002. When the contracts finished in 2002, 70% of the Hawaiian Islands was successfully collected at a cost of +1.2 Million.<br />
Hawaiian Islands<br />December 2009<br /><ul><li> As a result of the Emerge Aerial acquisition collection, Satellite Technology was considered for the subsequence collection.
USDA- NRCS started using Satellite acquisition in 2005 with primary DigitalGlobe. Complete statewide acquisition was finished in 2009.
- Oahuis collected by DHS/NGA/USGS as part of the Urban 133 areas project.
All islands have DG .6 Meter Resolution, Four Band Orthoimagery data except Oahu (1 Ft., Natural Color).
Complete coverage was accomplished in 2009 with the deliveries of DOQQ’s for Hawaii Island at a cost of ~ $ 600,000 including Enterprise Premium upgrades.</li></li></ul><li>Original Source QB Imagery (Top) and USDA-NRCS Tone Balanced Imagery (Bottom).<br />USDA has made available both original GeoTIFF files (Top) and processed imagery files bottom to Federal and State Agencies.<br />
What is the next generation of Orthoimagery for Hawaii?<br />
8/13/2010<br />DigitalGlobe Proprietary<br />Constellation Covering the Spectrum<br />21<br />
<ul><li> WorldView-2 has a 50cm “visible” panchromatic band (Narrower than QuickBird)
8 Multispectral Bands @ 1.8m native resolution – to support more “spectral” or analytical applications;
WorldView-2 satellite incorporates the industry standard four multispectral bands </li></ul> -- Red, Blue, Green, Near-Infrared<br /><ul><li> Adds Four (4) additional (NEW) bands</li></ul> -- Coastal Blue, Yellow, Red Edge, Longer Wave Near-Infrared (NIR2).<br />WorldView-2 Higher Spatial and Spectral Resolution!<br />
WorldView-2 Traditional Spectral Bands<br />Blue (0.45 - 0.51 µm)<br />MS4 is designed for water body penetration, making it useful for coastal water mapping. Also, useful for soil/vegetation discrimination, forest type mapping and cultural feature identification. <br />Green (0.51 -0.58 µm)<br />MS3 is useful for measuring green reflectance of vegetation. It can also be used for cultural feature identification.<br />Red (0.63 -0.69 µm)<br />MS2 is sensitive to chlorophyll absorption region. It is useful for vegetation analysis and can even be used to differentiate plant types. It is also useful for cultural feature identification.<br />Near Infrared (NIR1) (0.77 -0.895 µm)<br />This band is useful for determining vegetation types, vigor and biomass survey, delineating water bodies, and for soil moisture discrimination.<br />
New WorldView-2 Spectral Bands<br />Coastal band<br />Determine water depth in littoral zones <br />Vegetation identification and analysis based on chlorophyll and water penetration characteristics <br />Atmospheric correction.<br />Yellow<br />Ability to reproduce true color <br />Vegetation analysis<br />Red Edge<br />Vegetative analysis, directly related to plant health revealed through chlorophyll production<br />NIR2<br />Spectral analysis, overlaps with NIR-1 but less affected by atmospheric influence, <br />Vegetative analysis and biomass studies<br />

DG/WorldView-2 Orthoimagery Acquisition Information <br />and <br />Hawaii and Pacific Basin Image Samples<br />
<ul><li>USGS, State of Hawaii and USDA will contract for complete coverage of all 8 major Hawaiian Islands with DigitalGlobe/WorldView-2 Satellite Orthoimagery.
ALL of Hawaii will be collected with DigitalGlobe – WorldView-2, 8 Band Multi-Spectral Imagery!
Hawaii will be the first state with complete coverage of High Resolution Multi-Spectral data!</li></li></ul><li>New Imagery Notification for Hawaii – Pacific Basin<br />
World-View-2 Eight Band Research Questions?<br />Here is the basic set of questions that we are trying to have researchers address. I’m not sure what stage you are at in your research but hopefully these questions can at least guide you as to what information we are trying to collect.<br /><ul><li>What is the hypothesis you are testing, or the project you are working on?
What are the early results/indications for improvements with WV-2 data?
How does this compare to results based on QB data?
Can you quantify the improvements in terms of efficiency/speed/productivity/manual intervention?
When will you have quantitative data and can we publish it as a research / case study?
Can you provide us your ground truth so that we can do our own analyses?
Do you have an idea of how this research would be applicable to existing commercial markets or applications?
Have you conducted other studies with traditional 4 band imagery? </li></li></ul><li>DigitalGlobe 8 Band Multi-Spectral <br />Pan Sharpening Testing at USDA-NRCS<br />- In the past USDA has acquired Pan-Sharpen data from Orthoimagery DigitalGlobe. <br />- Cost considerations and the necessity to acquire native MS/Pan data prompted USDA/USGS to not contract for Pan Sharpen Orthoimagery.<br /><ul><li>With the acquisition of DG-WV2, 8 Band Multi-Spectral / Pan Band data, testing is needed to determine best available Pan-Sharpen Techniques.
Pan Sharpening testing has been started in ERDAS 2010, The following methods have been tested as of August, 2010.
DigitalGlobe Pan Sharpening Summary<br /><ul><li>USDA/USGS/SOH will acquire 8 Band Multi-Spectral / Pan Band to allow Remote Sensing Analysis on original acquired imagery.
USDA will continue to test Pan Sharpening techniques and hopefully distribute both 8 Band MS / Pan Orthoimagery and Pan Sharpen Imagery. DG does not offer 8 Band Pan Sharpening.
As of August, 2010 the best Pan Sharpen technique tested in Erdas 2010:</li></ul> - Resolution Merge, Method = Brovey Transform, Resampling Technique= Bilinear Interpolation<br />
DigitalGlobe/WorldView-2 Applications?<br />Summary:<br /><ul><li>In a short time period it is very difficult to show all the potential applications of DG/WorldView-2 Multi-Spectral data.
Possible application may include Habitat assessment, Invasive Species Detection, Bathymetric/Benthic, Vegetation Analysis, Land Use/Land Cover Mapping, Soil Mapping etc..
Suggestion for HIGICC/Interested Users receive a Web Training session(s) from DigitalGlobe when the first DG/WV-2 Disc for Hawaii/Pacific Basin is released.
The tentative date for release is October, 2010. </li></li></ul><li>Hawaii Orthoimagery <br />Data Distribution<br /><ul><li>All USDA distributed data for Hawaii has a Enterprise Premium License.
NRCS will work with USGS-EDC for placing the Enterprise Premium datasets into Seamless Server. NRCS-NCGC has delivered to USGS-EDC a complete dataset for Hawaii </li></ul>Distribution points of contact are....<br /><ul><li>For USDA Only Please contact</li></ul> Patricia Shade (808)-541-2600, x 120 (email@example.com)<br /><ul><li>or Tony Kimmet (817)-509-3434 (firstname.lastname@example.org )</li></ul>Outside USDA Please Contact: <br /> Henry Wolter (USGS-HI), (808)-587-2409, (email@example.com)<br />
<ul><li> USDA-NRCS with the help of the USFS upgraded all USDA acquired DigitalGlobe QB2 Orthoimagery for Hawaii and the Pacific Basin to Enterprise Premium.
USGS and State of Hawaii have agreed that the Enterprise Premium License will meet their agency application requirements.
Allows USDA to post compressed Orthoimagery mosaics of all Hawaii/Pacific Basin QuickBird data to the Public on the USDA Gateway. All users (Federal Civil/Defense, State, Local, Educational, General Public, US Territories/Trusts) except for profit companies have access to these datasets. </li></li></ul><li>DigitalGlobe Enterprise Premium License would allow the following.<br />- Allows USDA to post compressed mosaics of all QuickBird data listed in Appendix A on the “Public” side of the USDA Gateway. All users would have access to these datasets. The USDA Gateway is also the compressed raster data distribution portal for Imagery for the Nation (IFTN).<br />- Allows QuickBird data to be hosted on a Web Map Service (WMS) available to the General Public if the site does not charge a fee for the service. <br />- All Federal/State/Local Government, Universities, Non-Profit Organizations and the General Public would be allowed to use DG Satellite data. <br />
DigitalGlobe Enterprise Premium License exclusions.<br />- DigitalGlobe currently does not offer a “Public Domain” license for QuickBird data. The Enterprise Premium License is the most open license available from DigitalGlobe.<br />- The only exclusion in broad terms of the Enterprise Premium License is that DigitalGlobe QuickBird Imagery data itself could not be re-sold by anyone else (Vendors, Universities etc..). Please refer to Appendix C and D for more information on exclusions to Enterprise Premium. <br />
