Hawaii and Pacific Basin UpdateApril 28th, 2011
Topics
1) Hawaii DigitalGlobe QuickBird-2 Acquisition2) Hawaii DigitalGlobe WorldView-2 Acquisition Status3) Differences in DG-WV2 datasets4) Pacific Basin Satellite Acquisition (DG-QB2/WV2/, GeoEye-1)5) End User License Agreement Information6) Data Sizes 7) Distribution Strategy
• USDA- NRCS started using Satellite acquisition in 2005 with primary DigitalGlobe. Complete statewide acquisition was finished in 2009.
• - Oahu is 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.
• The complete Hawaii dataset including IfSAR Elevation data was distributed in early 2010!

DigitalGlobe WorldView-2 Summary
- Most islands will be delivered when complete approved coverage is available so DigitalGlobe can Radiometric balance the Imagery. Big Island will be in 2-3 pieces. Data delivered is Pan/8 Band MS, 16 Bit, Radiometric Balanced in GeoTIFF format, Metadata with Shapefiles etc..
- Hawaii Funding contribution were adequate for either DigitalGlobe Pan/8 Multi-Spectral Band (8 Band Bundle) or 4 Band Pan-Sharpen product but not for both products. We (USDA, USGS, SOH) decided to acquire the DG-WV2 8 Band Bundle.
- USDA has been working on Pan-Sharpening techniques. Recently we were able to Pan Sharpen all WV-2 Multi-Spectral Bands (8) for all Hawaiian islands using the following:
- ERDAS 2011, 64 Bit mode on a MS-64 Bit Workstation with quad processing ores and 2 TB of temp hard disc space.
- DigitalGlobe does a slightly better Pan-Sharpening with their Software/Hardware by are limited to 4 Band Pan-Sharpening.
• USGS, State of Hawaii and USDA have contracted for complete coverage of all 8 major Hawaiian Islands with DigitalGlobe/WorldView-2 Satellite Orthoimagery.
• Hawaii will be first state with complete collection with DigitalGlobe – WorldView-2, 8 Band Multi-Spectral Imagery!

Maui WV2 Test Files
- USDA received 4 different test files for West Maui.
A: Original Values, 16 BitB: Radiometric Balance, 16 BitC: 8 Bit, DRA On D: 8 Bit, DRA Off
- Several test sites were selected for evaluation including USGS/Hawaii and the County of Maui.
Production Notes:
- DRA is the equivalent to applying a Standard Deviation Stench
- Pan Sharpen mosaics were produced using consistent procedure in ERDAS

Pacific Basin Status
• USDA has collected approximately ~ 98% of all land mass within the jurisdiction of the United States:
- Guam- Commonwealth of the Northern Mariana Islands- Northwestern Hawaiian Islands- Palau- American Samoa- Federated States of Micronesia- Marshall Islands - US Trusts (Palmyra, Wake, etc..)
• Most islands acquired also contain any visible shallow water reef areas.• All data is Satellite 1 Meter or higher resolution (DG-QB2, DG-WV2, GeoEye-1)• USDA upgraded most but not all DG-QB2 data to Enterprise Premium License in
Fall 2009.• Funding would not allow complete Enterprise Premium Licenses in Pacific Basin.• Enterprise Premium (100% DG-QB2, DG-WV2) for: Guam, CNMI, Palau, American
Samoa, NWHI (except 1)• The following have a mixture Enterprise Premium and NGA NextView/Civil
Government: Marshall Islands, Federated States of Micronesia and US Trusts.

Most Islands/Atolls above are Orthoimagery however some were originally produced as Georeferenced due to a lack of DEM’s before 2007 when SRTM became available.
USDA Orthoimagery Acquisitions, Part 2
Federated States of Micronesia
Most islands with large populations were ordered via USDA-FAS or USGS-MCMC with Enterprise Premium Licenses.
• Pacific Basin Excel file will be released with the Pacific Basin dataset listing all important information including Sensor, Image Acquisition Dates and License Level.
• Most islands with large populations were ordered via USDA-FAS or USGS-MCMC with Enterprise Premium Licenses.
• Because of cost considerations less populated areas were ordered via NGA with NextView/Civil Government License.

Data Distribution
Total dataset size is 6 Terabytes
1) Hawaii WV2 (Oahu, Maui, Kauai, Hawaii/Partial, Niihau, Kahoolawe) = 3 TB
2) Pacific Basin including the new WV2 datasets = 2.5 TB
Data will be distributed on 3 Portable Hard Discs (2 TB Each)
- USGS-Hawaii (2 Sets)
- USGS-RMMC, then USGS-EDC (1 Set) for NGA
- USDA-NRCS (Hawaii), then USDA-FSA
- NOAA (CSC, Erik Hund) then to Tim Battista
- NPS (Custom)
- Alaska Dept. Transportation (FAA, Hawaii)
As always, if you have any funding please consider investing in Satellite Imagery with USDA and USGS!
Thank You for your time!
