along the 3D polyline in equal increments that are less than or equal to the
supplementing distance.
supplementing factors Add vertices along 3D polylines that are long and
contain few vertices. The supplementing distance is the maximum distance
between vertices. If the distance between vertices is greater than specified,
then points are added along the 3D polyline in equal increments that are less
than or equal to the supplementing distance. The smaller the distance, the
greater the number of supplemented points.
surface A network of elevation data. AutoCAD Map 3D supports raster-based
grid surfaces, such as DEM, DTED, and ESRI Grid. In these types of surfaces,
the points of a surface are connected into a grid, which are then used to
interpolate contours, and to generate profiles and cross-sections. A surface
represents the ground condition at a particular time or event.
surface layer A layer in
Display Manager (page 2060) containing a raster-based
surface such as a Digital Elevation Model (DEM), an ESRI Grid file, or Digital
Terrain Elevation Data (DTED). A surface layer is brought in using Data
Connect. See also
feature layer (page 2063), drawing layer (page 2060), AutoCAD
layer
(page 2056).
swing tie A type of measurement taken by a surveyor using a known distance
plus an angular offset. A tie is a direct measurement, made with a tape or
chain. Swing refers to the angle offset of the tie.
symbol A bitmap or vector image that is used to represent a point.
symbol library In MapGuide Studio, a collection of related symbols. Image
files are converted into symbols when they are brought into the symbol library.
The symbol library is stored in the resource repository.
symbol table A term referring to the storage of named objects, including
linetypes, layers, text styles, and blocks.
table A set of data arranged in records (rows) and fields (columns). When a
table is displayed in a grid, records display in horizontal rows and fields display
in vertical columns. Each field value in the table displays in a cell.
Task Pane A AutoCAD Map 3D window that provides the tools you require
to accomplish your main mapping tasks: creating, displaying, styling,
analyzing, and publishing maps. The Task Pane contains tabbed views:
Map
Explorer
(page 2068), Display Manager (page 2060), Survey, and Map Book (page
2067). Map Explorer enables you to manage the resources you use to create your
maps. Display Manager provides tools to create maps, and create styles and
themes. With Map Book, you can print, publish and share maps. You can
resize and move the Task Pane palette.
