分片（分幅）处理
TimeStamper
Adds a time stamp to a feature as a new attribute.
时间戳，按指定格式将当前时间输出为新的属性
TINGenerator
Generates a Delaunay surface model and outputs the defining Triangulated Irregular Network (TIN). The TIN is output as both Triangles and TIN Edges.

TopologyBuilder
Computes topology on input point, line, and/or area features.
对输入的点、线、面构建拓扑
UniformRasterClassifier
Classifies a raster into uniform-sized classes.
将栅格分类为统一大小的类别
UUIDGenerator
Calculates a UUID (Universally Unique IDentifier) for each incoming feature, and adds it as a new attribute. UUIDs look like: 7672aac8-fa0b-464c-b0b8-3efa9ae9cd86
对所有输入要素分别计算UUID（全局唯一标识），并输出为新的属性。例如：7672aac8-fa0b-464c-b0b8-3efa9ae9cd86
valueMapper
Performs a lookup of the value of an attribute in a lookup table, and stores the looked-up value in a new attribute.
查询对照表，结果输出为新的属性
VariableRasterClassifier
Classifies a raster into variable-sized classes.
将栅格分类为允许不同大小的类别
Visualizer
Sends features to the FME Universal Viewer for display.
将要素发送到FME Universal Viewer显示
VoronoiCellGenerator
Generates a polygonal coverage showing the coverage of cells from a given site.
