Previous: Mathematical Transformation of Raster Data
In this tutorial, you will learn how to define a coordinate system in FME Workbench and how to reproject data to another coordinate system using theReprojectorTransformer.

In this scenario, you want to define the projection of your dataset to match the coordinate system information that is stated in a metadata file. The polygon boundary you will use was inadvertently projected to the wrong coordinate system (UTM83-11) so you want to define the correct projection (UTM83-10) before performing your analysis.
The easiest way to define a coordinate system in FME is in the Add Reader dialog.
Alternatively, you can set the reader/writer’s Coordinate System in the Navigator window. See theUsing Coordinate Systems within FMEarticle for more information.
In Exercise 2, you will reproject data because it is currently using the LL83 Coordinate system (measured in degrees) and you need it to be in a coordinate system that uses linear units. In this scenario, you will reproject data from lat/long LL83 (degrees) to UTM83-10 (meters).
