Using ArcCatalog

overshoot
The portion of an arc digitized past its intersection with another
arc. See also dangling arc.
pan
To move an onscreen display window up, down, or across a map
image without changing the viewing scale. See also zoom.
password
A secret series of characters that enables a user to access a
computer, datafile, or program. The user must enter his or her
password before the computer will respond to commands. The
password helps ensure that unauthorized users do not access the
computer, file, or program.
path
In computing, the location of a computer file, given as the drive,
directories, subdirectories, and file name, in that order.
path label
Describes the nature of the association between the objects in a
relationship. The forward path label describes the relationship
when navigating from the origin to the destination; for example,
station points have measurements. The backward path label
describes the same relationship navigating from the destination
to the origin, which might be are taken at in this example;
measurements are taken at stations.
PC ARC/INFO coverage
A coverage created with PC ARC/INFO.
personal geodatabase
A geodatabase that stores data in a single-user relational
database management system (RDBMS). A personal geodatabase
can be read simultaneously by several users, but only one user at
a time can write data into it.
pixel
1. The smallest element of a display device, such as a video
monitor, that can be independently assigned attributes, such as
color and intensity. The term is an abbreviation for picture
element.
2. The smallest unit of information in an image or raster map.
Usually square or rectangular, pixel is often used synonymously
with cell.
pixel type
See data type.
planar coordinate system
A two-dimensional measurement system that locates features on
a map based on their distance from an origin (0,0) along two axes,
a horizontal x-axis, representing east–west and a vertical y-axis,
representing north–south.
port number
The TCP/IP port number on which an ArcSDE geodatabase
service is communicating.
pre-7.0 coverage
Coverages created with a version of ArcInfo prior to version 7
can’t be accessed by ArcCatalog and ArcMap until after the
ConvertWorkspace command has been used to modify the
coverage workspace.
precision
1. The closeness of a repeated set of observations of the same
quantity to one another. It is a measure of the control over
random error. Assessment of the quality of a surveyor’s work is
based in part on the precision of their measured values.
2. Refers to the number of significant digits used to store
coordinate values. Precision is important for accurate feature
