This page contains a glossary of terms commonly used in XMS. Many of these terms have usage specific to XMS and may or may not coincide with how these terms are used elsewhere.
A
- arc
- sequences of line segments or edges, which are grouped together as a single "polyline" entity.
- arc group
- multiple arcs that have been grouped together so they can be selected at once.
B
- breakline
- a series of edges to which the mesh or scatter triangles should conform.
C
- centerline
- arc that represents the direction of a river from upstream to downstream.
- contour
- a curve along which the function has a constant value.
- coverage
- groups of feature objects in the Map module.
- cross section
- arcs used to extract elevations in SMS and WMS. In GMS cross sections are flat surfaces used to visualize the subsurface.
D
- dialog
- a window that pops up after a command is executed. May also be called a window, tool, or editor.
E
- element
- used to describe the area to be modeled. Elements are formed by joining nodes. May be 1D, triangular, or quadratic.
F
- feature object
- patterned after Geographic Information Systems (GIS) objects and include points, nodes, arcs, and polygons.
- flow trace
- animation technique used to visualize vector fields.
G
- graphics window
- the main portion of the XMS program that gives a visual representation of the project.
H
I
- isosurace
- a surface of constant value extracted from a 3D dataset.
J
K
L
M
- macro
- button that executes a commonly used command.
- menu
- a list of commands. Can be found at the top of the XMS interface or by right-clicking on items.
N
- node
- define the beginning and ending XY locations of an arc.
- nodestring
- a collection of nodes.
O
P
- plot axes
- a set of ruled lines oriented in either the world coordinate system or the grid coordinate system.
- point
- XY locations that are not attached to an arc.
- polygon
- a group of connected arcs that form a closed loop.
- project explorer
- the portion of the interface that lists datasets and components of the project.
Q
R
S
- spectral energy
- represents energy densities at discrete values over a range of angles and a range of frequencies for a given wave condition.
T
U
V
- vertex
- XY locations along arcs in between the beginning and ending nodes.
W
X
Y
Z
