Or they could represent a multispectral image set. Common multiframe file
formats include GeoTIFF and NITF.
multispectral image data Data recorded in the form of multiple bands. Each
band records the values in a specific range of the spectrum, such as infrared,
visible, or ultraviolet. Data gathered by satellites is typically provided in
multispectral format. A band assignment color map is used to create false color
images from these bands. The color map can be configured to highlight surface
features, such as vegetation and water.
native capture Copies a REM object using the image data directly from the
image file, ignoring display scale and rotation of objects. Used only for the
REM Copy To Clipboard command.
nearest neighbor A pixel resampling method that assigns to a new pixel the
value of the closest pixel in the original image. This is the fastest resampling
method, but it produces the crudest results.
Never Detach An option in the Raster Design Options dialog box that does
not detach an image even if all image frames that reference the image are
erased from the drawing.
NITF National Imaging Transmission Format. This multiframe image format
is commonly used by US federal agencies and NATO.
node In v, a link end point that can be represented as a block or point object.
Example: You can force the line follower to ignore the intermediate nodes
and draw a single straight line between the start and end points of a line.
noise Random pixels that can result from poorly scanned images.
non-georeferenced image An image that does not include real-world
coordinate information.
non-linear contrast stretch See equalization.
non-orthogonal image A graphic representation that intersects or lies at
angles other than right angles. Also called non-ortho image.
ortho-corrected image An image that is corrected so all pixels represent their
true locations on the face of the earth, making directions and distances
accurate. Errors resulting from parallax, lens distortion, and other causes are
corrected.
orthogonal Intersecting or lying at right angles (0, 90, 180, or 270 degrees).
palette The range of up to 256 colors used in an 8-bit image.
