Reprojecting Point Data

Most coordinate conversion tasks are easy to perform with FME. Wherever automated translations are possible, reprojections are as simple as choosing different reader and writer coordinate systems. The FME features are coordinate system aware and reproject themselves appropriately.

However, when coordinate data is held in attribute values, this process cannot be completely automated. Tabular data stored in ASCII files cannot be translated automatically. In this case, you must use the AttributeReprojector transformer to accomplish this task.

1. Insert the transformer and connect it to the feature type(s) .
2. Select the X and Y coordinate values.
3. Select the source (reader) and destination (writer) coordinate systems.

This transformer does not alter the feature’s coordinates – only the values of the selected X and Y attributes (if they contain coordinate values) are changed.

Note: Make sure you have not also specified reader and writer coordinate systems through the Navigator pane in FME Workbench.
