Exam Questions and CORRECT Answers
.shp file* - CORRECT 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* - CORRECT ANSWER - The data frame currently being worked on -
for example, the data frame to which layers are being added. The active data frame is highlighted
on the map, and its name is shown in bold text in the table of contents.
active layer - CORRECT ANSWER - The layer that is currently active.
arc* - CORRECT ANSWER - 1. On a map, a shape defined by a connected series of
unique x,y coordinate pairs. An arc may be straight or curved.
2. a coverage feature class that represents lines and polygon boundaries. One line feature can
contain many arcs. Arcs are topologically linked to nodes and to polygons. Their attributes are
stored in an arc attribute table (AAT). Nodes indicate the endpoints and intersections of arcs;
they do not exist as independent features. Together, the from-node and the to-node define the
direction of the arc
ArcGIS* - CORRECT ANSWER - A suite consisting of a group of geographic information
system (GIS) software products produced by ESRI. It is a system for working with maps and
geographic information. It is used for: creating and using maps; compiling geogrpahic data;
analyzing mapped information; sharing and discovering geographic information; ;using maps
and geogrpahic information in a range of applications; and managing geographic information in
a database.
ArcGIS documents - CORRECT ANSWER - it is the map blah blah
area feature - CORRECT ANSWER - One of the three types of features: point, line, and
area. The area feature is a 2D plane produced by a polygon of a certain shape.
,arithmetic function - CORRECT ANSWER - A type of methematical function that
performs a calculation on the values of cells in an input raster. There are six arithmetic functions
in ArcGIS Spatial Analyst: Abs, Int, Float, Round up (Ceil), Round down (Floor) and Negate
Operators - CORRECT ANSWER - Arithmetic - *, /, -, +
Boolean - True or False
Relational - ==, >, <, <>, >=, <=
ASCII files* - CORRECT ANSWER - "American Standard Code for Information
Interchange". The de facto standard for the format of text files in computers and on the internet
that assigns an 8-bit binary number to each alphanumeric or special character. ASCII defines 256
possible characters.
attributes* - CORRECT ANSWER - Nonspatial information about a geogrpahic feature in
a GIS, usually stored in a table and linked to the feature by a unique identifier. For example,
attributes of a river might include its name, length, and sediment load at a gauging station.
attribute query* - CORRECT ANSWER - A request for records of features in a table based
on their attribute values
attribute table - CORRECT 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 - CORRECT ANSWER - Field are the columns. Records
are the rows.
auto-label* - CORRECT ANSWER - A tool that automatically labels a certain layer based
on a selected field (usually NAME)
, bitmap* - CORRECT 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* - CORRECT 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 - CORRECT 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).
byte - CORRECT ANSWER - The smallest addressable unit of data storage within a
computer; almost always equivalent to 8 bits and containing one character.
CAD - CORRECT ANSWER - (Computer-Aided Design). A computer-based system for
the design, drafting, and display of graphical information. Such systems are mostly commonly
used to support engineering, planning, and illustrating activities.
CAD feature class - CORRECT ANSWER - A read-only member of a CAD feature
dataset, comprised of one of the following: polylines, points, polygons, multipatch, or
annotation. The feature attribute table of a CAD feature class is a virtual table comprised of
select CAD graphic properties and any existing field attributes values.
cell* - CORRECT ANSWER - The smallest unit of information in raster data, usually
square in shape. In a map or GIS dataset, each cell represents a portion of the earth, such as a
square meter or square mile, and usually has an attribute value associated with it, such as soil
type or vegetation class.
