Attribute Table
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.

Attribute tables
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.

Attribute tables
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 attribute table (VAT) Value attribute table. 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.

Attribute table display - view and query the attributes associated with your data.

An attribute table is a table that contains information on the associated spatial feature(s) in a View.

The attribute tables can be sorted in ascending or descending alphanumeric order.
Sorting is done by activating a field in the attribute table 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: ...

GPS (Global Positioning System) - A system of radio-emitting and -receiving satellites used for determining positions on the earth.

Record: In an attribute table this would consist of a single "row" of descriptors for one feature in contrast to an item or field or column which consists of a single attribute descriptor.

SELECT denotes what attribute table fields you wish to view.
FROM denotes the attribute table in which the information resides.

A data type referring to text columns in an attribute table (such as NAME). Choropleth A choropleth map portrays a statistical surface with area symbols (colours), which represent the collection regions, inferring uniformity within these units e.

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 attribute table 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 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 attribute tables 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.

A single row of thematic characteristics in an attribute table.
Shaded Relief
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 attribute table, or be represented by series of attribute tables on the same objects through time

Attribute Information about a geographic feature in a GIS (computer record), generally stored in a table and linked to the feature by a unique identifier. Attribute tables for individual or multiple features can be accessed with the Identify, Search, ...

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 attribute tables 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.
