Definitions for "Data Layer"
Refers to data having similar characteristics being contained in the same plane or overlay (e.g., roads, rivers). Usually information contained in a data layer is related and is designed to be used with other layers.
An individual file; a single layer that can be added to a GIS project. Potentially many data layers make up a single data set. Not all of the library's spatial data holdings have information provided at the individual data layer. Only our best, most frequently used, and most current data is described in such detail. What is the difference between data sets and data layers (in the GIS Data Finder)
The layer on an optical disc that holds data as marks or pits. They affect the amount of laser light that is reflected back to the laser photosensor.
