MrSID Generation 3 Format Named Standard

LizardTech (WA, USA) has announced that the US Department of Agriculture (USDA) has named MrSID Generation 3 image Format as the standard to be used for all 2005 Compressed County Mosaics (CCM).

Last year, the USDA Aerial Photography Field Office (APFO) issued a baseline contract for aerial imagery as part of the National Agriculture Imagery Program. One of the deliverables in the Program was a Compressed County Mosaic, which was required in MrSID Generation 2 Format. This year USDA has modified the Contract to require that all CCMs be delivered in MrSID Generation 3 Format.

USDA makes CCMs available to the public for a nominal fee. Imagery is acquired on an annual basis to support the USDA Farm Service Agency’s crop and commodity programs and must be acquired between May and the end of September 2005. The mosaics are delivered in UTM coordinate systems compressed to MrSID Generation 3 Format (MG3). Customers using it will benefit from the new flexibility that MG3 offers over any other compressed image format due to the ability to reproject and compress the images at differing compression ratios within the same mosaic. These features will allow broader use of the imagery by users who work in State Plane coordinate systems and those with limited bandwidth.
