contour lines
A line that connects points of the same elevation or value relative to a
specified reference datum. The lines can help you determine the elevation at a specific
location on a surface. They help clarify and analyze the 3D surface terrain, and help with
tasks such as navigation.
coordinate system
See
global coordinate system
(page 312)
.
Create Method
A setting on the Class Settings tab of the Define Object Classification dialog
box. It determines the method used to create new objects from this class (when you right-click
the object class and choose Create Classified Object).
Data Connect
AutoCAD Map 3D window where you can access a
data store
(page 310)
and
add specific data to your map. Display the Data Connect window by clicking Data in
Map
Explorer
(page 312)
or
Display Manager
(page 310)
(in the
Task Pane
(page 315)
).
data provider
Used by Data Connect to connect to geospatial
data store
(page 310)
s.
data store
A collection of
feature class
(page 311)
es contained in a single data storage location.
The data store contains feature classes defined within one or more schemas. Data stores can
be files, such as an SDF file, or databases, such as an Oracle Spatial database.
Data Table
In AutoCAD Map 3D, the
feature
(page 311)
-based grid where you can view and
edit attributes of selected spatial features, perform searches, and work with selection sets.
DEM
Digital Elevation Model. A file that contains a representation of surface terrain. The
surface is stored as a grid. Each grid cell can have any one of several different meanings,
such as elevation, color, density, and so on.
digitize
To convert existing data from paper maps, aerial photos, or
raster
(page 314)
images
into digital form by tracing the maps on a digitizer. Object locations are recorded as X,Y
coordinates.
Display Manager
A tab in the
Task Pane
(page 315)
that handles the styling and theming of
feature
(page 311)
s in your map.
display map
All the settings for a specific map, such as the data to include, the appearance
of each
layer
(page 312)
, and the legend definition. A display map can include objects from
attached drawings,
raster
(page 314)
images, and
feature
(page 311)
s stored in
data store
(page
310)
s. For example, it can include data from Oracle databases, SDF or SHP files, and ArcSDE.
One map can include multiple display maps.
draping
The process of displaying a set of features or a
raster
(page 314)
image on a surface
so that the features or the image reflect the underlying terrain.
Draw Query
A query that retrieves objects (copies them into the current drawing). You can
manipulate and edit the objects. You can save them back to their attached drawings, save
them to the current drawing, or save them to a new drawing.
