What is the matrix

Frames table schema

ArcMap 10.4
|

This is a list of recognized and supported fields for the frames table of the frame camera raster type. This table enables specification of parameters that control exterior orientation (EO).

The frames table can be stored in several formats: a geodatabase table, feature class table, raster catalog, or a *.csv file. Listed below are all of the supported fields. At the end of this page is an example frames table.

Note:

A parameter definition in the frames table take precedence over any duplicate definitions within the cameras table.

List of fields supported in the frames table

Field nameField typeData typeDescription

Raster

Required

String

The path to the image file or the RASTER column, if you are using a raster catalog.

CameraID

Required

String

A unique field within the cameras table, from where the orientation parameters are loaded.

PerspectiveX

Required

Numeric

The x-coordinate of the perspective center, in the ground coordinate system. The units are in the coordinate system units.

The geographic coordinate system units are not currently supported. Specify the PerspectiveX value in projected coordinate system units.

PerspectiveY

Required

Numeric

The y-coordinate of the perspective center in the ground coordinate system. The units are in the coordinate system units.

The geographic coordinate system units are not currently supported. Specify the PerspectiveY value in projected coordinate system units.

PerspectiveZ

Required

Numeric

The z-coordinate value of the perspective center in the ground coordinate system. The units are the z coordinate system units if z coordinate system exists, otherwise it defaults to meter.

Omega

Required*

Numeric

The rotational angle of the camera's x-axis in degrees. The units are in decimal degrees.

Phi

Required*

Numeric

The rotational angle of the camera's y-axis in degrees. The units are in decimal degrees.

Kappa

Required*

Numeric

The rotational angle of the camera's z-axis in degrees. The units are in decimal degrees.

Matrix

Required*

String

The matrix describing the transformation from image-space to map-space.

The matrix is specified as nine floating-point values, which are delimited by spaces or semicolons.

Shape

Optional

Geometry

The polygon identifying the region containing valid image data. This polygon becomes the footprint of the corresponding mosaic dataset item.

Name

Optional

String

An alias name to identify the image. If this is left blank, the image file name is used.

Tag

Optional

String

A tag that enables the image to participate in a function template.

GroupName

Optional

String

An optional categorization for images. All images with the same group name participate together in a function template.

StripName

Optional

String

The name of the strip (run).

SRS

Optional

String

Coordinate system associated with the perspective point as WKT-PRJ string or file path or EPSG code. Defaults to data-specified or mosaic dataset SR. The spatial reference can be defined for each image item in the mosaic dataset as well. If SRS field is defined both in the cameras table and the frames table, the value in frames table will take precedent.

Note:

Required*—The frames table must have either the Omega, Phi, and Kappa fields, or the Matrix field in order for the data to be added to the mosaic dataset. If both types of EO exist in the table, the transformation matrix value will be used.

Example frames table

Below is an example frames table stored as a geodatabase table, and where only a selection of the available fields are being used. Since are only four frames (images) being used in this example, there are only four rows in the table.
