Landsat FAST L7A A multispectral image format used by Landsat 7 satellite,
which was launched in 1999.

layout Management of images, to determine how they are displayed and in
what order they are listed in the Image Management dialog box.
what order they are listed in the Image Management dialog box.
linetype The display style of a line, such as continuous or dashed.
low pass filter A means of extracting individual elements in areas where pixel
intensities change rapidly, thereby reducing high-frequency detail. The effect
is a slightly blurred image.

LZW A file compression algorithm, commonly used with TIFF and GIF files.
Maintain Drawing Link A ProdNameShort export option that, if selected,
overrides the image you selected to export.
overrides the image you selected to export.
mask An object used to display and plot a subset of the images in your
drawing. A mask clips the images inside the mask boundary and hides or
unloads the images completely outside the mask boundary. The mask boundary
is an AutoCAD object that you can move, stretch, scale, and erase, like any
other AutoCAD object.

median filter A convolving filter that removes random visual speckles from
an image by changing each pixel value to match the average value of the
neighboring pixels.

merge commands ProdNameShort commands used to merge images, merge
vectors into raster images, and select raster pen widths.
vectors into raster images, and select raster pen widths.
merge images To group two or more images into a single image file.
mirror To create a new version of an existing object by reflecting it in relation
to a line or plane. Example: Scanning software might mirror a drawing, or
you might scan the back of a drawing by mistake. You can correct these
problems by mirroring the image.

Mitchell A pixel resampling method that uses a cubic spline technique. It is
widely considered to provide a good compromise between ringing and blurring
artifacts on most images. See also blurring artifacts, ringing artifacts.

monolithic Encoding method for TIFF files. Saves image data in one piece,
and may result in slower processing time. See also data organization.

multiframe image data An image type that includes multiple related images
within a single file. Each image is in a separate frame, and the images are
usually related. For example, they could represent a series of drawings, pages
from a document, an animation sequence.
