Feature Representation

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

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).
