Table Of Contents
task workflow An overview of the steps to perform common GIS tasks.
template file A file that formats another file, such as a text file for saving
information from queried objects. See also dot variable (page 2060), query (page
2072), and
link template (page 2067).
text layer Static text stored as a separate SDF data store, independent from
the current map. You can precisely position text on the layer, and style and
rotate the text.
thematic map See theme (page 2077).
theme A theme is a special style used to vary the stylization based on some
property of the objects. For example, instead of just coloring the lakes blue,
you could vary the shade of blue based on the depth of the lake. Instead of
just altering the line width of the roads, you could vary the line width based
on traffic flow.
theming The process of styling
feature (page 2063) according to an attribute
value. See also
styling (page 2075).
tiling scheme The method of breaking a large map into multiple smaller tiles.
Options include by area, by number, and custom.
tolerance A radius around a node or linear object used to search for drawing
errors.
tolerance (drawing cleanup) The minimum distance allowed between linear
objects or nodes during drawing cleanup. If two linear objects or nodes are
separated by a distance less than the tolerance, AutoCAD Map 3D corrects the
error.
Topobase An Autodesk data management solution for utility companies,
municipalities, and engineering firms. Autodesk Topobase consists of a set of
industry-specific modules built on AutoCAD Map 3D and MapGuide, all of
which use Oracle as the central data store.
topology A set of geometric relationships between drawing objects, including
links, nodes, and centroids. Topology describes how lines, nodes, and polygons
connect and relate to each other, and forms the basis for advanced GIS
functions such as network tracing, spatial analysis, buffer analysis, overlay
analysis, and dissolving a polygon topology.
topology query An extension to a Map query that applies to a loaded topology.
See also
map query (page 2068).
transparent command A command started while another is in progress.
Precede transparent commands with an apostrophe.
