Setting up the reprojection

In the Reproject window, under Reprojection Bounds, the projection information of the selected source file is displayed.

To set up the reprojection

Under Reprojection Bounds, in the unlabeled list, click the projection method you want.
You can choose from:
- Use pixels/lines and bounds
- Use pixels/lines and resolution
- Use bounds and resolution
Beside Size, type the number of pixels and lines for the reprojection in the Pixels and Lines boxes, respectively.
Beside Pixel Size, type the size of the pixels along the x and y axes in the X and Y boxes, respectively.
In the unlabeled list, click the coordinate system you want.
You can choose from:
- Pixel: Measured in data pixels and lines; georeferencing is unknown
- UTM: Universal Transverse Mercator (and zone)
- Long/Lat: Longitude/latitude or geographic
- Meter: Measured in relative meters; world location is unknown
- Foot: Measured in U.S. Survey feet
- SPCS: State Plane Coordinate System (and zone)
- Other: Generic or user projection
To modify the datum or ellipsoid to use in the reprojection:
1. Click Earth Model
2. In the Earth Models window, select the datum and ellipsoid you want, and then click OK.
To add additional projection information, click More.
To the right of the Earth Model button, the text box displays the full georeferencing string in active use. This includes the georeferencing coordinate system, plus the zone number and earth model, where applicable.

For example: UTM 6 Q D000

The box displays the coordinate system, the zone and row, then the earth model. This information is generated automatically when you select an Earth model and zone. You can edit the information directly, if necessary.

For more information about projections and Earth models, see Introduction to projections and Earth models.
To set the boundaries of the reprojected area:
1. In the Bounds list, click the interpretation method you want for the reprojection bounds.
  - Geocoded: Bound values are interpreted in the georeferenced units based on the selected coordinate system.
  - Geographic: Bound values are interpreted in values based on longitude and latitude.
2. In the boxes beside Upper Left, type the horizontal and vertical position of the top-left corner of the area.
  The values you enter are the upper and left edges of the upper-left pixel for raster images.
3. In the boxes beside Lower Right, type the horizontal and vertical position of the bottom-right extent of the area.
  The values you enter are the lower and right edges of the lower-right pixel.
  
  To reset the bounds to their original values, click Maximum Bounds.
In the Resampling list, click the resampling method you want to use for image reprojection.
You can choose from:
- Nearest neighbor (default value)
- Bi-Linear
- Cubic
