X-Y digitizing tablet : A peripheral device for manually translating line and point data (like engineering and technical drawings) into some computer format (usually vector or CAD).
Digitizing tablets have been used since the early days of GIS, in order to capture coordinate map data. A digitizer is a special table embedded below the surface with a series wires.
Thus: digitizing tablet or scan-and-trace? I had conflicting advice
from members of this list, pro and con both, and I had absolutely
no previous experience of either procedure. For my purposes -- ...

If the digitizing table is not flat, I strongly recommend using the crank under the table to make it so. The streaming function in ArcGIS is easier with a flat table than a vertical one.

To employ a digitizing tablet to record x,y or x,y,z values for map features. Lines are traced to define their shape. A digitizer button, pressed periodically along the line, records x,y coordinates.
A way of using a digitizing tablet in which locations on the tablet are mapped to specific locations on the screen. Moving the digitizer puck on the tablet surface causes the screen pointer to move to precisely the same position on the screen.
Also called a digitizing table. Discrete Data Categorical data such as types of vegetation, or class data such as speed zones. In geographical terms, discrete data can be represented by polygons. Sometimes referred to as integer data.
The operator uses a pointing device (mouse or trackball) to navigate on the scanned image of the original source, without having to look down at a digitizing tablet. heuristic p.
In computer Cartography and GIS, the vector data structures were first to be used because they were created simply from the digitizing tablets, they better represented the complex features like land parcels, ...
A digitizing station, a workstation which is connected to a precision digitizing tablet, which utilizes a high-resolution display terminal, and which also has all of the analysis functions necessary for querying, displaying and editing data ...
A digitizing workstation with a digitizing tablet and cursor is typically used to trace digitize. Both the tablet and cursor are connected to a computer that controls their functions.
Manual digitizing: Digitization is done directly over the raster by the use of a digitizing tablet, which is a manual pointing device that creates an identical vector map on the computer screen, defining the vertices, points, line data, etc.
5 topo maps in TIFF format and imported this to Erdas/Imagine and georeferenced this to the hardcopy version on a digitizing tablet (fig. 1.a).
We can use existing maps as inputs by tracing contour lines on a digitizing tablet or table. The data are organized into cell arrays whose X-Y positions in the rectangular grid are related to map coordinates.
Hardware vendors continued to improve digitizing equipment, with manual digitizing tablets giving way to automated scanners at many GIS facilities.
Calibration: In vector mapping, the adjustment of the digitizing tablet so that a location on the manual map corresponds to the location of the cursor within the display of the spatial database.
For example, the GIS (or CAD) operator will trace the boundary of each state with a digitizing tablet or mouse. Boundaries common to pairs of states will therefore be traced twice.
Digitizer - An electronic device for capturing digital data from paper maps. Small-size digitizers are usually referred to as digitizing tablets, and large-size ones are called digitizing tables.

Modern GIS technology can automate this process fully for large projects using scanning technology; smaller jobs may require some manual digitizing (using a digitizing table).
Later other options were added, such as a large digitizing tablet, and a hard drive (hard drives usually did not exist on computers this size). The hard drive was a CDC-Wren about the size of a small washing machine.

Maps can be digitized by hand-tracing with a computer mouse on the screen or on a digitizing tablet to collect the coordinates of features. Electronic scanners can also convert maps to digits (fig. 7).
Digitize is the process of converting source materials, prepared manually, into the digital codes stored and processed by computers. Digitizing involves tracing map features into a computer using a digitizing tablet, graphics tablet, mouse, ...
Digitizer A device used to capture planar coordinate data, usually as x and y coordinates, from existing analog maps for digital use within a computerized program such as a GIS. Also called a digitizing table.
