Most importantly, they define two specific things: the layers being written to a destination dataset, and the attributes that those layers will possess. Objects on the Workbench canvas that define the schema of the data being written. Most importantly, they define two specific things: the layers being read from a source dataset, and the attributes that those layers possess. Objects on the Workbench canvas that define the schema of the data being read. The process of connecting source feature types to destination feature types. The display continuously updates as features pass through the workspace. The feature count display in FME Workbench shows how many features passed through each connection. However, the "Group By" parameter in a transformer can define several groups based on the value of an attribute. In FME, we call this set of features a "group." By default, the group is ALL features entering the transformer. Features in FME have a flexible, generic representation they have a basic FME definition that is unrelated to the format from which they originated.įME transformers can carry out transformations on either one feature at a time, or on a whole set of features at once. FME can restructure either of these components.
#MEANING OF FME PLUS#
Typically a GIS or cartographic feature consists of a geometric representation plus a set of related attributes. At the user level, factories are used by transformers.Ī feature in FME is an individual item within the translation. They can operate on zero or more FME features, producing zero or more FME features. The component of FME that processes job requests by running workspaces.įactories are core-level FME components. The name and location of the workspace output.
#MEANING OF FME VERIFICATION#
Any existing sequence of transformers can be turned into a custom transformerĭatabase connections provide a convenient and secure way to store and reuse connection parameters to a database service.Īn FME Desktop tool for viewing data in any FME-supported format for verification and debugging purposes.Īn FME Server service that accepts and runs transformation requests, as specified by a workspace, and returns the results as a data stream.Īn FME Server service that allows users to upload source data or other files for running workspaces. Once created, it will be accessible from the Reader/Writer Gallery.Ī custom transformer is a sequence of standard transformers condensed into a single transformer. Coordinate Systems can be set in the Navigator pane.Ī custom format is a workspace (reader) that can be used to preprocess data, as if it were a data format on its own. FME will automatically try to determine the correct coordinate system from the dataset, for formats that store coordinate system information (for example, Shapefiles). This definition is called a "workspace" and can be saved for re-use later.Įach reader and writer in a workspace is assigned a coordinate system. The FME Workbench canvas is where users graphically define a translation. Running a workspace with breakpoints is a useful way to debug a workspace. The attribute may have been part of a source dataset or may have been created within FME.Īdding a breakpoint to a workspace connection tells Workbench to inspect the features at that location. User-created information that belongs to a feature. The act of restructuring the non-spatial component of an FME feature: the attributes relating to the physical geometry undergo a change that produces a different output. The process of connecting source feature type attributes to destination feature type attributes. FME attributes are prefixed with "fme" (for example, fme_geometry or fme_color). It contains information about the data that is used internally by FME. Format attributes are prefixed with the format abbreviation, for example igds_level or autocad_color.Īn attribute that is generated by FME when a source dataset is read. In this example, the feature type is Zone and the attributes are Name, Owner, and Category.Īn attribute that contains data that is part of the format specification.
