uniDEM supports reprojection, mosaicking of DEM editing along with undo, redo and reverting of edits performed on a DEM. Additionally, a detailed edit history can be retrieved for every pixel in an active dataset.
The undo feature can be used to undo edits that were performed when making selections, classifications, editing DEMs or collecting geometries.
Default shortcut: Ctrl-Z
The redo feature can be used to redo edits that were undone after making selections, classifications, editing DEMs or collecting geometries.
Default shortcut: Ctrl-Y
The revert feature can be used to return a DEM to it's original incoming values. When a DEM is set as the active dataset a backup file is with the DEM file name and a "~" is created (ex. SomeDEM.tif~). This holds the original DEM data.
Default shortcut: none
Reproject allows the projection of a raster or geometry to be changed.
The projection can be selected from a drop-down menu or the EPSG code can be entered directly by selecting Other in the drop-down.
Default shortcut: none
Move provides a lightweight method to assign a new projection and coordinates to a DEM or Image raster.
This feature can be used for a tif that is received without geocoding or complete projection information.
Note: This feature requires knowledge of the corresponding pixel location of a given tie point.
To move a dataset 3 locations and the corresponding pixel locations are required.
The following steps are performed:

The Mosaic tool supports merging of one or more rasters of the same kind into one raster within the defined selection.
