EsriReprojector
Reprojects特性 coordinates from one coordinate system to another using the Esri reprojection library.
This transformer always reprojects from the source coordinate system to the destination coordinate system, tagging the features with the destination coordinate system on output.Any coordinate system set on the input features is ignored.
Dependencies
To use this transformer, you must have ArcGIS installed on the same machine as FME.
Parameters
Click the Browse button to display the Esri reprojection library.You can select a coordinate system, import a coordinate system, or create a new coordinate system.

A geographic transformation converts data between two geographic coordinate systems.Click这里to see a PDF of valid geographic transformation names for this parameter.Names of custom (user created) geographic transformations may also be used.
注意:The geographic transformation name is case-sensitive.If you do not enter the parameter in the correct case, FME will fail and produce an error saying it cannot locate the transformation parameter.
注意:Some geographic transformations require transformation grid files that are not present in ArcGIS by default.If such a transformation is chosen, no error will occur, and no geographic transformation will be applied to the features.Examples of installing additional grid shift files in ArcGIS can be found这里.
You can also enter GEOGTRAN Well Known Text that represents a geographic transformation.
注意:To use this feature, you must have an Esri CustomTransformations folder.ArcGIS Desktop installations automatically create this folder.The CustomTransformations path is specific to the ArcGIS version and type (Server, Desktop, etc.).
ArcGIS 10.0 Example:
%APPDATA%\ ESRI \ Server10.0 \ ArcToolbox中\ CustomTransformations
ArcGIS 9.3.1 Example:
%APPDATA%\ ESRI \ ArcToolbox中\ CustomTransformations
这是geotransformation方向(无论是“正向”或“反向”)。
The Interpolation Type affects only raster data.Cell values are interpolated in order to change the raster to the specified size.
- 最近的邻居是最快的,但产生最差的图像质量。
- 双线性提供速度和质量的一个合理的平衡。
- 双立方是最慢的,但产生最佳的图像质量。
- 平均4和平均16有类似双线性性能,并且是数字栅格等的DEM是有用的。
The Cell Size applies only to raster features.
- 方形单元:行和列的数量,以及所述间隔将被改变,以保持大约相同的细胞的接地面积,并形成正方形电池,其中水平和垂直的小区大小是相等的。像方形单元选项,保留单元格会改变的行和列,并保持细胞接地区的间距的两端的数量,而且会尽量保留原始细胞比例,考虑到造成重投影任何变形。
- 弹力细胞:光栅的细胞大小将被调整以维持相同数量的行和列中的重新投影的光栅因为有输入栅格。
Usage Notes
This transformer is not affected by raster band and palette selection.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace.More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers.To access a menu of these options, clickbeside the applicable parameter.For more information, seeTransformer Parameter Menu Options.
