![]() Another example uses this function on the raster item in a mosaic dataset. Since the mosaic dataset cannot be reprojected, you can do one of two things-either create a referenced mosaic dataset from your mosaic dataset in the projection needed, or add the Reproject function to the mosaic dataset's function chain. ![]() For example, when creating a cached image service that may be integrated by applications with other cached services, it's important that they all be in the same projection. The Reproject function can be used when creating a cache from a raster or mosaic dataset that is not in the required projection. Therefore, if two images use the same origin and cell sizes, the pixels from the resampled images will coincide exactly in the overlap area, even if they came from images with different pixel sizes. The x,y origin is mainly used to enforce pixel alignment between multiple scenes, as in a cache. If both the X Cell Size and Y Cell Size parameters are greater than 0, then they are used along with the X Origin and Y Origin to define the output envelope. This coordinate must be defined in the units of the new spatial reference. Y Origin-The y-coordinate used to define the upper left corner of the dataset.X Origin-The x-coordinate used to define the upper left corner of the dataset.If the value is 0 or less, then the output envelope (extent and cell sizes) is calculated from the input raster. Y Cell Size-The y-dimension to which the data should be resampled.X Cell Size-The x-dimension to which the data should be resampled.Spatial Reference-The coordinate system used to reproject the data.The inputs for this function are the following: It can also resample the data to a new cell size and define an origin. ![]() The Reproject function modifies the projection of a raster dataset, mosaic dataset, or raster item in a mosaic dataset. ![]()
