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: ...
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.
The attribute table shows date and time in a user-friendly format, depending on your regional settings, rather than the underlying database's format. This is fine most of the time but also has a few drawbacks: ...

Attributes can be viewed through the attribute table such as within a shapefile.
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.
After you trace each feature, enter the feature's key identifier into the layer's attribute table (see Figure 2.20).
A union overlay combines the geographic features and s 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 attribute tables that describe characteristics and conditions of the map features.
Associated s 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.
A single row of thematic characteristics in an attribute table.
A method used to display topographic variation in a landscape using the perspective shadowing resulting from a hypothetical position of a light source.
depending on how the temporal mode is captured, it may be included in a single , or be represented by series of s on the same objects through time
