A range of wavelengths of electromagnetic radiation. Remote sensing devices commonly collect images in discrete bands, such as visible red, green, and blue, and the invisible near-infrared.
An image format that stores each band of data collected by multispectral satellite scanning instuments in a separate file.
A measure of the volume of data that can flow through a communications link. image data tend to exist as large datasets; thus moving image data sets from one computer to another requires high bandwidth or performance will be slowed. Also known as through put.
Science of measuring water depths (usually in the ocean) to determine bottom topography.
Relatively permanent material object, natural or artificial, bearing a marked point whose elevation above or below an adopted datum is known.
Material object placed on or near a boundary line to preserve and identify the location of the boundary line on the ground.
Survey made to establish or to reestablish a boundary line on the ground, or to obtain data for constructing a map or plat showing a boundary line.
Creating and/or adding points in a vector object from imported coordinate data (like text files that contain pairs of coordinates, or database files with fields representing pairs of coordinates).
