.shp file* - Answer-- a vector data storage format (shapefile) for storing the location, shape, and
attributes of geographic features.
- stored in a set of related files and contains one feature class.
active data frame* - Answer-The...
attribute table - Answer✔✔-A database or tabular file containing information about a set of geographic
features, usually arranged so that each row represents a feature and each column represents one
feature attribute. In raster datasets, each row of an attribute table corresponds to a certain zone of cells
having the same value. In a GIS, attribute tables are often joined or related to spatial data layers, and the
attribute values they contain can be used to find, query, and symbolize features or raster cells.
attribute table: field and records - Answer✔✔-Field are the columns. Records are the rows.
auto-label* - Answer✔✔-A tool that automatically labels a certain layer based on a selected field (usually
NAME)
bitmap* - Answer✔✔-An image format in which one or more bits represent each pixel on the screen.
The number of bits per pixel determines the shades of gray or number of colors that a bitmap can
represent
Boolean expression* - Answer✔✔-an expression, named for the English mathematician George Boole
(1815-1864), that results in a true or false (logical) condition. For example, in the Boolean expression
"HEIGHT > 70 AND DIAMETER = 100," all locations where the height is greater than 70 and the diameter
is equal to 100 would be given a value of 1, or true, and all locations where this criteria is not met would
be given a value of 0, or false.
Boolean operator - Answer✔✔-a logical operator used in the formulation of a Boolean expression.
Common Boolean operators include AND, which specifies a combination of conditions (A and B must be
true); OR, which specifies a list of alternative conditions (A or B must be true); NOT, which negates a
condition (A but not B must be true); and XOR (exclusive or), which makes conditions mutually exclusive
(A or B may be true but not both A and B).
