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.
在这种情况下,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.
在FME中定义坐标系的最简单方法是在“添加阅读器”对话框中。
Alternatively,您可以在导航器窗口中设置读写器的坐标系。See the在FME中使用坐标系article for more information.
在练习2中,您将重新投影数据,因为它当前使用的是LL83坐标系(以度为单位),您需要它位于使用线性单位的坐标系中。在这种情况下,您将把数据从lat/long ll83(度)重新投影到utm83-10(米)。
