Feature attribute table

Definition
Feature attribute tables are special sets of tables created for various feature  classes. Feature attribute tables are INFO data files that contain a number of predefined items and additional user-defined attributes for  each feature. A number of feature attribute tables can be created for coverage, each associated with a particular feature class. A feature attribute table is named after the coverage with a three-letter code  indicating the type of feature attribute table.

Description
The most commonly used address fields are in the attribute tables. The attribute table contains the following default fields:

ObjectID—the ObjectID field is maintained by ArcGIS and guarantees a unique ID for  each row in a table. It can be used as an image ID when using the Lock Raster mosaic method.

Raster—Stores the link to the raster dataset and any individual properties,  functions, or metadata. You can preview the processed raster by clicking in this field and clicking the arrow button that appears. In the window that appears, you can edit the functions and preview the properties and  metadata.

Name—Name of the source defined by the raster type, which can be the name of the raster  dataset file or the metadata file defined in the raster type

LowPS and HighPS—These values are extracted from the source rasters and  used to define the range of pixel sizes that the raster dataset  contains. For example, a raster dataset that contains a pyramid (or internal overview) will have a range of pixel sizes—the low value will  represent the base pixel value and the high value will represent the top  overview that is being used. For raster datasets with no pyramids, the low and high pixel sizes may be the same value.

Category— Used for quickly identifying the type of dataset and its status within the mosaic dataset:


 * 0—Unknown
 * 1—Primary (base) data
 * 2—Overview
 * 3—Unprocessed overview
 * 4—Partially processed overview
 * 253—Uploaded
 * 254—Incomplete and needs to be synchronized
 * 255—Custom item

Tag—Used for identifying the raster dataset that will participate in functions  defined in a function template. For example, importing one mosaic dataset to another using the Table raster type (with some function  templates defined on the raster type) heavily depends on Tag. In most cases, the value is defined by the raster type used for creating the  dataset entry within the table.

GroupName— A name given to one or more rows in the table that belong together. For example, for a QuickBird scene, the panchromatic and multispectral  rasters are added as separate items in the table. Since each is required to participate in pan sharpening when added using a particular raster  type, they will be assigned a group name. This is defined by the raster type that created the dataset entry within the table.

ProductName— This is derived from either the name or product type defined in the raster type.

CenterX and CenterY— The x- and y-coordinates identifying the centroid or  nadir of the raster dataset. They are used to render a mosaicked image when the mosaic method is Closest to Nadir or Closest To Viewpoint.

ZOrder— Overrides the default ordering used in determining how the rasters will  be mosaicked together. If the value is 0, the default ordering defined as part of the mosaic method is used. If the value is set to a number below 0, the raster is always displayed on top with a high priority. This can be used, for example, to display a lower-resolution raster with a specified footprint to cover areas that should not be seen at high  resolutions. The lower the value, the higher the display order. If the value is set above 1, the raster dataset is always displayed as a  background when no other raster exists covering the requested area. This can be used to provide a background image.

SOrder—Values in this field (not ZOrder) are used for sorting overlapping datasets  when using the Seam line mosaic method. This field is populated by the Build Seam lines tool based on the mosaic rule specified in the tool.

A number of feature attribute tables can be created for a coverage, each associated with a particular feature class. A feature attribute table is named after the coverage with a three-letter code  indicating the type of feature attribute table. For example, a coverage named LOTS that contains polygons will have a polygon attribute table  (PAT) named LOTS.pat.
