   • Format An image format supported by your exploitation tool. This format will be used when the image is delivered to your library. Depending on your account and the type of item you are saving, format options may include:

     • GeoTIFF (compressed) JPEG compression with YCbCr color space and 95% quality

     • JPEG Compressed format with a small file size; suitable for inserting into PowerPoint and documents

     • MrSid Compressed 15:1; a good choice for large areas where file size is an issue

     • JPEG2000 Compressed; a good choice for large areas where file size is an issue

     • GeoPDF A georeferenced PDF for use in tools that can read that format

     • NITF 2.1 (NPJE JP2 4:1) Embedded metadata; useful for military applications that require this format

     • NITF 2.1 (NPJE JP2 15:1) Embedded metadata; useful for military applications that require this format and when file size is too large with 4:1 compression

     • RPF 0.5 Meter, 1 Meter, or 5 Meter Suitable for those who need a CIB-like replacement

   • Compression The compression option for packaging files. Options include TAR (for Linux/Unix or Max) or ZIP (for Windows).
