A tabular file containing rows and columns. Descriptive attributes about some object, such as a geographic feature, are contained in each row. The same column in each row represents the same attribute.
Most GIS enable the user to view the data in tabular form without necessarily using map graphics at all. This is equivalent to using typical office spreadsheet software.
attribute tableAn INFO or other tabular file containing rows and columns. In ARC/INFO, attribute tables are associated with a class of geographic features, such as wells or roads. Each row represents a geographic feature.
Layer tables exist for every feature class (i.e., point, line, or polygon) layer added to a data frame.
feature attribute table : A table used by ARC/INFO to store attribute information for a specific coverage feature class. Feature attribute tables supported include: Cover.PAT for polygons or points Cover.AAT for arcsCover.NAT for nodes Cover.
value (VAT) Value . A table containing attributes for a grid. In addition to user-defined attributes, the VAT contains the values assigned to cells in the grid and a count of the cells with those values.
Attribute table is only created if it is needed, i.e. when at least one attribute column is present in the input file besides geometry columns. The attribute column types have to be declared along with the geometry columns using the columns parameter.

An attribute table is a table that contains information on the associated spatial feature(s) in a View.
The s can be sorted in ascending or descending alphanumeric order.
Sorting is done by activating a field in the and selecting the ascending or descending button.

Attribute table - A table that is attached to a data layer that contains many characteristics of a feature on a map.
The feature of the GIS coverage defines the geographic properties of the L spatial units and gives each a unique identifying number.
A union overlay combines the geographic features and attribute tables of both inputs into a single new output. An intersect overlay defines the area where both inputs overlap and retains a set of attribute fields for each.
In digital form these spatial data have been linked to s that describe characteristics and conditions of the map features.
Associated attribute tables include detailed finds information which enable the development of artefact distribution patterns, incorporating those finds recovered by the metal detector users, and during the controlled excavations.

Each table contains information relevant to a particular feature, and is linked to other tables by a common value. For example, two attribute tables could be linked to a spatial data table via a geocode, such as the postcode.
Tabular data describing the geographic characteristics of map features. Can include numbers, text, images, and CAD drawings about features. ARC/INFO stores descriptive data in feature s and in related tables.
In a coverage, features are stored as both primary features (points, arcs, polygons) and secondary features (tics, links, annotation). Feature attributes are described and stored independently in feature attribute tables.
