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. 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 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 Project Description
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 NORPC & Partners DMC Mission Green, Yellow, and Pink Boxes are project study areas
Detail of the New Orleans Project Area NOTE: Project areas were separated based on funding & client partners • Design Format – 8 CCD Frame Array (~14,000 X 7,000 Pixel Frame) • Pixel Resolution – 1.5” To 2M Pixel Size
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

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.
