Terrain Tiles on AWS 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).

Depending on the selected tile format, the raster interpretation may be 8-bit Red, Green, Blue or Alpha, or 16-bit Integer.

User attributes are not supported.

Attribute Name Contents

terraintiles_type

This will always be terraintiles_raster.

geotiff_area_or_point

Indicates whether each raster pixel represents an area or point. The value can be Area or Point.
geotiff_byte_order

The byte order of the file. When reading, values will be either MSB or LSB. When writing, valid values are MSB, LSB, and machine (meaning the native byte order of the machine running FME).

The default value when writing is machine.

geotiff_compression_
method

The compression used in the file. The available options are:

  • jpeg
  • lzw
  • pack-bits
  • ccitt-rle (CCITT modified Huffman run length encoding)
  • ccitt-fax3 (CCITT Group 3 fax encoding)
  • ccitt-fax4 (CCITT Group 4 fax encoding)
  • none

If not specified, the default value is none.
geotiff_interleaving_type

The organization of the bands in the file. Acceptable values are BIP, which is band interleaved by pixel, and BSQ, which is band sequential. BIP may be less efficient for reading and writing by FME, but is more widely supported by other applications. If not specified, the default interleaving is BSQ.

Note: This option corresponds to the PlanarConfiguration TIFF tag. BIP corresponds to a value of 1 (Chunky), and BSQ corresponds to a value of 2 (Planar).

geotiff_type

For GeoTIFF tiles. This will always be geotiff_raster if present.
area_or_point For Skadi tiles. Indicates whether each raster pixel represents an area or point. The value can be Area or Point.
srtmhgt_type For Skadi tiles. This will always be srtmhgt_raster if present.
