Defining the clip region with user-entered coordinates

You can define the clip region by manually entering coordinates for the exact area of the data you want to save as a subset. The following procedures follow step 7 in Clipping and subsetting images.

  1. In the Definition Method list box, choose User-entered Coordinates.
  2. In the Coordinate Type list box, choose one of the following formats to define the coordinates for the clip region:
    • Raster extents: defines the clip region by identifying upper-left and lower-right pixel and line coordinates.
    • Geocoded extents: defines the clip region by identifying the georeferenced coordinates of the upper-left and lower-right corners.
    • Long/Lat extents: defines the clip region by identifying the geographic coordinates of the upper-left and lower-right corners.
    • Raster offset/size: defines the clip region by identifying the pixel and line coordinates of the upper-left corner and providing the number of pixels in width and the number of line in length.
    • Geocoded offset/size: defines the clip region by identifying the georeferenced coordinates of the upper-left corner and providing width and length in the units of measurement of the input coordinate system.
  3. In the Upper Left boxes, type the coordinates for the top-left corner of the clip region.
    • If you selected Raster extents, Geocoded extents, or Long/Lat extents from the Coordinate Type list box, type the coordinates for the bottom-right corner of the clip region in the Lower Right boxes.
    • If you selected Raster offset/size from the Coordinate Type list box, type a value representing the number of pixels in the Width box and type a value representing the number of lines that you want to form the clip region in the Height box.
    • If you selected Geocoded offset/size from the Coordinate Type list box, identify the size of the clip region. Using the measurement unit of the projection, type the distance for the width in the Width box and type the distance for the height in the Height box.
  4. Click Clip.
  5. If you want to change a clip area with the bounding outline, do the following:
    1. In the Preview area, drag a bounding outline corner until you have the size you want.
    2. Drag the bounding outline to a new location.
    3. Click Clip.
