FME® Workbench Transformers Quick-Reference ... - Consortech

SpatialFilter Filters features based on
spatial relationships. Each input
CANDIDATE feature is compared
against all BASE features, based
on the selected tests to perform.
Tester Evaluates one or more tests on a feature and routes the feature according to
the outcome of the tests. The tests can consist of any FME-allowed operands.
TestFilter Filters features by test conditions to one or more output ports.
GEOMETRIC OPERATORS – These transformers operate on the geometry of individual features, or groups
of features. A wide variety of operations are available, including overlays, snapping, line labeling, clipping,
and intersection.
AffineWarper Performs warping operations on the spatial coordinates of features. It
is used to adjust a set of observed features so they more closely match
some set of reference features.
AnchoredSnapper Takes a series of features that match the input specification and performs
snapping on the features that lie within the specified tolerance from other
features that match the input specification.
AreaBuilder Takes a set of topologically connected linework and creates topologically
correct polygon features where the linework forms closed shapes.
AreaOnAreaOverlayer Performs an area-on-area overlay. All input areas are intersected against
each other, and resulting area features are created and output. The
resulting areas have all of the attributes from all the original features in
which they are contained.
