Table Of Contents
publish To generate output from a map book.
purge To remove all unused object definitions from an open drawing.
query A set of executable statements that retrieve specific objects. For example,
a layer-based query that displays only the objects on the layers that contain
state and district boundaries. See map query (page 2068), topology query (page
2077), and
database query (page 2059).
Query Library The set of queries saved in a drawing. You can add, delete, and
modify queries in the Query Library.
ramp A sequence of display properties used to render a theme; for example,
a sequence of colors, line styles, or hatch patterns.
range of values In a theme, a segment of data along a continuum, such as
property value, temperature, or population.
raster Images containing individual dots (called pixels or cells) with color
values, arranged in a rectangular, evenly spaced array. Aerial photographs and
satellite images are examples of raster images used in mapping. Compare with
vector (page 2078).
raster-based surface layer See
surface layer (page 2076).
reference point For a symbol, the point that controls the position of a symbol
over a feature in a map. The default reference point is the center of the symbol.
registration The preparation of a map for digitizing by calibrating a digitizing
table to convert an analog source to a digital file. See digitize (page 2059).
resistance Resistance is a measure of how hard it is to travel a link. The default
measure of resistance is the length of the link. You can set the resistance to
be related to what the link represents, such as pipe diameter or traffic speed.
resolution In a raster image, the density of pixels-per-inch (PPI) or
dots-per-inch.
resource In MapGuide, a feature source, drawing source, or application
component that is stored in the resource repository and can be reused and
shared.
resource (metadata) In the Metadata feature, a resource is a generic term
meaning any type of data set for which AutoCAD Map 3D can generate
metadata (page 2069). A resource could be a feature class, an object class, a
schema, or a file.
resource repository In MapGuide, an XML database that stores the resources
created either by loading file-based data or by connecting to databases.
