The Reproject function modifies the projection of a raster layer, or raster item in an imagery layer. It can also resample the data to a new cell size and define an origin.
Notes
The x,y origin is typically used to enforce pixel alignment between multiple scenes, as in a cache. Therefore, if two images use the same origin and pixel sizes, the pixels from the resampled images will coincide exactly in the overlap area, even if they came from images with different pixel sizes.
Parameters
| Parameter name | Description |
|---|---|
Raster | The raster to be reprojected or resampled. |
| Spatial Reference | The coordinate system used to reproject the data. |
X Cellsize | The x-dimension to which the data should be resampled. This is optional. If the value is 0 or less, the output envelope (extent and cell sizes) is calculated from the input raster. |
Y Cellsize | The y-dimension to which the data should be resampled. This is optional. If the value is 0 or less, the output envelope (extent and cell sizes) is calculated from the input raster. |
| X Registration Point | The x-coordinate used to define the upper left corner of the dataset. This coordinate must be defined in the units of the new spatial reference. If both the X Cellsize and Y Cellsize parameters are greater than 0, they are used along with the X Registration Point and Y Registration Point parameters to define the output envelope. |
| Y Registration Point | The y-coordinate used to define the upper left corner of the dataset. This coordinate must be defined in the units of the new spatial reference. If both the X Cellsize and Y Cellsize parameters are greater than 0, they are used along with the X Registration Point and Y Registration Point parameters to define the output envelope. |
