4 Project Description CLIENT: New Orleans Regional Planning Commission (NORPC) and Partner Agencies. STUDY AREA: 3,000 square miles in pocket areas across southern Louisiana for regions affected by Katrina and Rita. NEED: Post-Katrina and Rita digital orthophotography for urbanized areas and levee locations affected by the hurricanes.

5 Project Description DATA ACQUISITION: Spring 2006 flights 4,600’ AGL 60% forward lap, 30% sidelap 18,950 images flown DATA PROCESSING: 2 shifts for A/T and ortho generation Lots of manual edits in PhotoShop for sun glare PRODUCTS: DMC 6-inch orthophotos Ground control Reports Aerotriangulation Reports Ortho-rectified Mosaics

6 Project Description PRODUCT APPLICATIONS: Storm-damage environmental assessment Levee mapping and analysis Debris mapping and analysis (above-water and near-shore) Shoreline change detection General emergency response and preparedness for future events

7 The Z/I DMC Was Selected Because: Design Format – 8 CCD Frame Array (~14,000 X 7,000 Pixel Frame) Pixel Resolution – 1.5” To 2M Pixel Size Radiometric Resolution – 12-bit Native Resolution Multispectral Bands – Panchromatic, RGB, And Near IR With Overlapping Spectral Response Applications – Base Mapping, Engineering Studies, Photogrammetry, Remote Sensing

NORPC & Partners DMC Mission Green, Yellow, and Pink Boxes are project study areas

9 Detail of the New Orleans Project Area Design Format – 8 CCD Frame Array (~14,000 X 7,000 Pixel Frame) Pixel Resolution – 1.5” To 2M Pixel Size NOTE: Project areas were separated based on funding & client partners

10 Data Acquisition Issues Many of the priority areas were covered by 50% or more water, and the weather was uncooperative. Therefore, many areas had sun glare on the water during the acquisition window. Airborne GPS problems for part of the project required cross-strip flights to allow traditional aerotriangulation to be performed. NOTE: Fortunately the DMC can still be used without ABGPS

15 Claiborne Ave Bridge to Chalmette (Sample 2)

16 Levee Repairs (Sample 3)

17 Flooded & Destroyed Homes (sample 4)

18 Conclusions The Z/I DMC is a Very Versatile Digital Camera System. Multiple Products and Applications Can Be Easily Delivered. Ability to work without ABGPS and IMU can make the difference between success and failure. This project is helping Louisiana recover and prepare. The clients are very happy with the final products.
