Proposal Standard Products for Direct-Digital Resource

This document outlines the proposed standards for digital imagery products discussed at the USDA Imagery Planning Meeting on December 3, 2008. Emphasizing the importance of intended use, it specifies requirements for raw data and ortho images, including cloud cover, sun angle, and metadata standards. The proposal suggests standard formats for remote sensing products, such as 16-bit uncompressed TIFF images, GPS/IMU data, and georeferenced stereo coverage. It aims to establish consistent quality and usability for imagery applications in various fields.

  1. Proposal Standard Products for Direct-Digital Resource John Mootz APFO 2008 USDA Imagery Planning Meeting December 3, 2008

  2. Intended Use • Intended use will drive requirements • Pretty picture or raw data • Ortho image can always be created from raw data but reverse is not possible 16-bit 8-bit data loss 2008 USDA Imagery Planning Meeting

  3. Proposed Digital Image Standard • End product will be dependant on use • Deviation allowed but requires documentation/specifications • Common requirements • 4-band product (RGBN band order) • 0% cloud, min 30° sun angle • FGDC metadata 2008 USDA Imagery Planning Meeting

  4. Remote Sensing Product • 30cm GSD (?) • 16-bit, unstretched image • Uncompressed TIFF (with TWF) • No AUX or RRD files • Single point georeferenced (UTM) • Stereo coverage • 62%/30% optimum endlap/sidelap • Native camera footprint* • Standard flight line naming convention • Other data deliverables: GPS/IMU • Format standards needed 2008 USDA Imagery Planning Meeting

  5. GIS Product • Stereo Pairs • Same as remote sensing except 8-bit, color balanced image • ortho • 60cm GSD (?) • 8-bit, color balanced image • Uncompressed GeoTIFF • DOQQ footprint (mosaic) and naming convention 2008 USDA Imagery Planning Meeting
