TIFF 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.

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

Attribute Name	Reader or Writer Attribute	Contents
tiff_type		This will always be `tiff_raster`.
tiff_area_or_point	Reader attribute	Indicates whether each raster pixel represents an area or point. The value can be Area or Point.
tiff_subdataset_name		When this is present on a feature, the feature is a subdataset. This attribute shows the name of the subdataset.
tiff_subdataset_description		When this is present on a feature, the feature is a subdataset. This attribute gives a description of the subdataset.
tiff_documentname		Represents the name of the document from which this image was scanned.
tiff_imagedescription		Represents a string that describes the subject of the image.
tiff_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.
tiff_software		Represents the name and version number of the software package(s) used to create the image.
tiff_resolutionunit		The unit of measurement for `tiff_xresolution` and `tiff_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.
tiff_xresolution		Represents the number of pixels per `tiff_resolutionunit` in the x direction.
tiff_yresolution		Represents the number of pixels per `tiff_resolutionunit` in the y direction.
tiff_artist		Represents the person who created the image. Some older TIFF files used this tag for storing copyright information.
tiff_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.”
tiff_hostcomputer		It represents the computer and/or operating system in use at the time of image creation.
tiff_maxsamplevalue		The maximum data value used.
tiff_minsamplevalue		The minimum data value used.
