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.

GeoTIFF features specify a matrix of x, y, and z coordinates. For each raster, there will only be a single feature returned.

Attribute Name	Contents
geotiff_type	This will always be `geotiff_raster`.
geotiff_area_or_point	Indicates whether each raster pixel represents an area or point. The value can be Area or Point.
geotiff_subdataset_name	When this is present on a feature, the feature is a subdataset. This attribute shows the name of the subdataset.
geotiff_subdataset_description	When this is present on a feature, the feature is a subdataset. This attribute gives a description of the subdataset.
geotiff_tifftag_ documentname	Represents the name of the document from which this image was scanned.
geotiff_tifftag_ imagedescription	Represents a string that describes the subject of the image.
geotiff_tifftag_datetime	Represents a date and time of image creation. When writing, the string must have the following format to be accepted: “YYYYMMDDHHMMSS”, without any separator or delimiter. Hours range from 0 to 23.
geotiff_tifftag_software	Represents the name and version number of the software package(s) used to create the image.
geotiff_tifftag_ resolutionunit	The unit of measurement for `geotiff_tifftag_xresolution` and `geotiff_tifftag_yresolution`. The possible values are 1, which means that there is no absolute unit of measurement and is usually used for images, 2, which means inches, and 3, which means centimeters.
geotiff_tifftag_ xresolution	Represents the number of pixels per `geotiff_tifftag_resolutionunit` in the x direction.
geotiff_tifftag_ yresolution	Represents the number of pixels per `geotiff_tifftag_resolutionunit` in the y direction.
geotiff_tifftag_artist	Represents the person who created the image. Some older Tiff files used this tag for storing Copyright information.
geotiff_tifftag_copyright	Represents the copyright notice of the person or organization that claims the copyright to the image. The complete copyright statement should be listed in this field including any dates and statements of claims. For example, “Copyright, John Smith, 19xx. All rights reserved.”
geotiff_tifftag_hostcomputer	Represents the computer and/or operating system in use at the time of image creation.
geotiff_tifftag_classification	Security Classification. This is a private TIFF tag used by the NGA.
geotiff_tifftag_commercialimageid	Commercial Image ID. This is a private TIFF tag used by the NGA.
geotiff_tifftag_countrycode	Country Code. This is a private TIFF tag used by the NGA.
geotiff_tifftag_productcreationdate	Source image creation date. This is a private TIFF tag used by the NGA.
geotiff_tifftag_productcreationtime	Source image creation time. This is a private TIFF tag used by the NGA.
geotiff_tifftag_sic	Security Indicator Code. This is a private TIFF tag used by the NGA.
geotiff_tifftag_maxsamplevalue	The maximum data value used.
geotiff_tifftag_minsamplevalue	The minimum data value used.
geotiff_world_file_ generation	Enables or disables the generation of an Esri world file along with the output image. The value can be yes or no (case-sensitive). The default is no. This is a writer attribute.
geotiff_tab_file_ generation	Enables or disables the generation of a TAB file along with the output image. The value can be yes or no. The default value is yes. This is a writer attribute.
geotiff_create_tiled_ files	Enables or disables the creations of tiled GeoTIFF images. By default, it is disabled (the value no), and stripped GeoTIFF images are created. The value can be yes or no (case-sensitive). This is a writer attribute.
geotiff_tile_size_x	Specifies the number of columns in a tile. This option only applies when creating a tiled file; strips are required to be the full width of the raster. This value is required to be a multiple of 16. If no value is specified, this parameter will be determined from the tile size of the input raster. This is a writer attribute.
geotiff_tile_size_y	Specifies the number of rows in a tile or strip. If no value is specified, this parameter will be determined from the tile size of the input raster. Note that other options may impact this value: If creating a tiled file, this must be a multiple of 16. If applying JPEG compression, this must be a multiple of 8. If applying JPEG compression with a photometric interpretation of YCbCr, this must be a multiple of 16. This is a writer attribute.
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_jpeg_compression_ level	Sets the quality of the compression if jpeg is the value for `geotiff_compression_method`. The range of the value is from 0 (best quality) to 100 (worst quality). The default value is 25. This is a writer attribute.
geotiff_number_of_bits_ per_cell	The number of bits per cell in the file, if it is not a power of 2 (i.e. 8, 16, or 32). Valid values are 1 - 32. If the bit depth is a power of 2, this value does not need to be specified. Note: Previously the string "8-or-above" was equivalent to leaving this value blank. When this value is specified, the interpretation of the input raster bands must be the minimum power of 2 above the requested bit depth. For example, to write 7-bit data, the interpretation must be one of UINT8, GRAY8, RED8, GREEN8, BLUE8, or ALPHA8. Please see the writer overview above for more details on the use of this parameter when writing.
geotiff_enable_bigtiff	Allows the writer to produce a file larger than 4GB when the value is set to yes. If the value is set to no or left empty, the BigTIFF support is not enabled.
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_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_calculate_minmax_tifftags	Specifies whether the writer should calculate the MinSampleValue and MaxSampleValue TIFF tags values from the input raster. Calculating the min/max values may increase translation time. Note that if this is set to Yes, the calculated values will override any explicit values specified for geotiff_tifftag_minsamplevalue and geotiff_tifftag_maxsamplevalue. This is a writer attribute.
geotiff_photometric_interpretation	The color space of the image data. The available options are: Auto: The photometric interpretation will be implicitly determined from the FME interpretation. MinIsBlack: The minimum value of the raster should be displayed as black. This option applies only to numeric rasters. MinIsWhite: The minimum value of the raster should be displayed as white. This option applies only to numeric rasters. YCbCr: The values should be stored using the YCbCr color space. This option is only valid when using JPEG compression.
