ADRG (ARC Digitized Raster Graphics) Feature Representation

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).

ADRG features specify a matrix of x, y coordinates and 3-byte RGB pixels.

Attribute Name

Contents

adrg_type

This will always be adrg_raster.

adrg_noz

The number of zone image files.

adrg_rty

The record id number.

adrg_prt

The product type.

adrg_nam

The ZDR image name.

adrg_zna

The ARC zone number.

adrg_swo

The westernmost longitude of the extent within the zone (including the overlapped region) of the unpadded cartographic image in arc degrees.

adrg_swa

The southernmost latitude of the extent within the zone (including the overlapped region) of the unpadded cartographic image in arc degrees.

adrg_neo

The easternmost longitude of the extent within the zone (including the overlapped region) of the unpadded cartographic image in arc degrees.

adrg_nea

The northernmost latitude of the extent within the zone (including the overlapped region) of the unpadded cartographic image in arc degrees.

adrg_arv

The ARC value Asz (adjusted for scale and zone), which is the number of pixels per 360 degrees longitude.

adrg_brv

The ARC value Bs (adjected for scale), which is the number of pixels per 360 degrees latitude.

adrg_lso

The longitude of the upper left corner of the ZDR image in WGS 84 coordinates.

adrg_pso

The latitude of the upper left corner of the ZDR image in WGS 84 coordinates.

adrg_txt

Free text (e.g., digitizing system description).

adrg_nul

The row number of the upper right corner of the ZDR image (in pixels).

adrg_nus

The column number of the upper right corner of the ZDR image (in pixels).

adrg_nll

The row number of the lower left corner of the ZDR image (in pixels).

adrg_nls

The column number of the lower left corner of the ZDR image (in pixels).

adrg_nfl

The image height (in tiles).

adrg_nfc

The image width (in tiles).

adrg_pnc

The number of pixels per tile row.

adrg_pnl

The number of rows per tile.

adrg_pcb

The number of bits per pixel count.

adrg_pvb

The number of bits per pixel value.

adrg_bad

The GEO DATA FILE name.

adrg_ws1

The lower band edge wavelength in nanometers.

adrg_ws2

The upper band edge wavelength in nanometers.

adrg_tif

The tile index map flag (true indicates there are tiles with no data; false indicates that all tiles contain RGB graphic data).
