ASRP (ARC Standard Raster Product) Feature Representation

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

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

Attribute Name

Contents

asrp_type

This will always be asrp_raster.

asrp_noz

The number of zone image files.

asrp_rty

The record id number.

asrp_prt

The product type.

asrp_nam

The ZDR image name.

asrp_zna

The ARC zone number.

asrp_swo

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

asrp_swa

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

asrp_neo

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

asrp_nea

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

asrp_arv

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

asrp_brv

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

asrp_lso

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

asrp_pso

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

asrp_txt

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

asrp_nul

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

asrp_nus

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

asrp_nll

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

asrp_nls

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

asrp_nfl

The image height (in tiles).

asrp_nfc

The image width (in tiles).

asrp_pnc

The number of pixels per tile row.

asrp_pnl

The number of rows per tile.

asrp_pcb

The number of bits per pixel count.

asrp_pvb

The number of bits per pixel value.

asrp_bad

The GEO DATA FILE name.

asrp_ws1

The ON-color-code value (0 - 255)

asrp_ws2

The OFF-color-code value (0 - 255)

asrp_tif

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