aggregate functions
In MapBasic, functions such as Sum( ) and Count( ) that calculate summary information about groups
of rows in a table. See Select in the MapBasic Reference Guide or Help System.
Browser window
In MapInfo Professional, a window for viewing a table (or database, spreadsheet or text file) in tabular
form.
coordinate
An x,y location in a Cartesian coordinate system, or a Latitude, Longitude location in an earth coordinate
system. Coordinates represent locations on a map relative to other locations. Earth coordinate systems
may use the equator and the Greenwich prime meridian as fixed reference points. Plane coordinate
systems describe a two-dimensional x,y location in terms of distance from a fixed reference and are
usually in the first quadrant so that all coordinates are positive numbers.
degrees longitude, degrees latitude, decimal degrees
Degrees (longitude and latitude) are coordinates used to represent locations on the surface of the earth.
Longitude, or X-coordinate, represents a location’s east-west position, where any location west of the
prime meridian has a negative X value. Latitude, or Y-coordinate, represents a location’s north-south
position, where any location south of the equator has a negative Y value.
field
In MapInfo Professional, a field in a table corresponds to a column in a Browser. A field contains a specific
type of information about an object, such as, name, abbreviation, land area, price, population, and so
forth. The record for each object consists of that object’s values for each of the fields in the database.
graticule
A grid of horizontal (latitude) and vertical (longitude) lines displayed on an earth map, spaced at a regular
distance (for example, every five degrees, every fifteen degrees). Used to establish a frame of reference.
latitude
The horizontal lines on a map that increase from 0 degrees at the Equator to 90 degrees at both the
North (+90.0 degrees) and South (-90.0 degrees) poles. Used to describe the North-South position of a
point as measured usually in degrees or decimal degrees above or below the equator.
legend
The part of a map, which explains the meaning of different colors, shapes, or fill patterns used on the
map.
