discrete data Data that falls into explicit categories. For a feature layer (page
2063) that uses a
theme (page 2077), each value is displayed differently. For
example, an agricultural thematic map might show each crop in a different
color. Compare with continuous data (page 2058).
display information A description of the appearance of a drawing object:
includes items such as layer, color, hatch pattern, and line type.
Display Manager A view of the
Task Pane (page 2076) that shows each Display
Manager layer
(page 2060) in your current display map, and has commands for
styling and managing those layers. To view Display Manager, select its tab in
the Task Pane.
Display Manager layer A set of objects in
Display Manager (page 2060). The set
could be all the objects on a layer or in a
feature class (page 2063), or objects that
share a certain property. Each layer can be styled or themed individually.
display map A set of map presentations, consisting of Display Manager layers,
that can be stored in a DWG file. See
Display Manager layer (page 2060).
display properties Same as
display information (page 2060).
dissolve To remove the boundaries that exist between polygons sharing a
specific attribute.
dither To use a pattern of solid dots to simulate more colors than are available
when displaying images.
domain (metadata) In the Metadata feature, the domain refers to element
values that are defined as valid within the FGDC CSDGM Standard (page 2063).
A domain can be a list of pre-defined values in a menu, a range of numbers,
free-form text, or any other type of value that can be assigned to a given field.
dot variable Variable that refers to an object property. It consists of a period
(.) followed by the variable name for that property. Dot variables can be entered
in expressions used for building a template file for Report mode queries and
for property alteration. See also
query (page 2072) and expression (page 2062).
draping The process of overlaying
feature (page 2063) or a raster (page 2072) image
on a surface so that the features or the image reflect the underlying terrain.
draping The process of overlaying a set of feature (page 2063) or a raster (page
2072) image on a surface so that the features or the image reflect the underlying
terrain.
drawing layer A layer in
Display Manager (page 2060) that contains drawing
objects
(page 2061) from a DWG file. See also AutoCAD layer (page 2056), feature
layer
(page 2063), layer (page 2066), surface layer (page 2076).
