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 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).
