Reprojecting an Image

To reproject an image, you must set a CRS for the source image and for the output image. You can reproject images to the MrSID Generation 4 (MG4), MrSID Generation 3 (MG3), JPEG 2000, and NITF 2.1 output formats.

  1. Click the Reproject button on the toolbar.

    The Reprojection Manager dialog box appears.

  2. Select the Reproject Image check box at upper left.

  3. If the source image has a known CRS, then that CRS is displayed. Otherwise, click Select Coordinate Reference System in the Source Image panel to select a source CRS.

  4. To set the projection for the output image, click Select Coordinate Reference System in the Output Image panel.
  5. Optionally, click Advanced Options to set additional reprojection options.
  6. Click OK.

NOTE: When you reproject an image, you affect the image's pixel data. As a result, you should always reproject an image before you perform other image manipulation operations, especially cropping or defining an area of interest.
