(Note: The NAIP08 county files are the first data that MnGeo has distributed in JPEG 2000 format. We will add information to this page as we use the format more extensively. If you have suggestions for additional information to provide, please let us know: gisinfo.mngeo@state.mn.us )


What is JPEG 2000?

JPEG 2000 is a wavelet-based data format that allows image files to be substantially compressed with little to no loss of image quality. This format, created by the Joint Photographic Experts Group committee, allows you to view any portion of a JPEG 2000 image at any resolution very quickly. It is similar to MrSID and ER Mapper formats; however, it is based on an open standard so it can be used by anyone.

How do I look at JPEG 2000 files?

You may look at JPEG 2000 files with some web browsers or with some geographic information systems (GIS) software packages.

Note: USDA reports that ER Mapper and some earlier ESRI software releases have had trouble converting NAIP JPEG 2000 formatted files. They are working to resolve those problems.
