To create an empty raster dataset in a geodatabase, see Creating raster datasets in a geodatabase.
- In ArcCatalog or the Catalog window, right-click the empty geodatabase raster dataset, point to Load, then click Load Data.
- Click the Input Rasters browse button
and navigate to the location of the Input raster dataset you want to load, then select it.
You can add more than one.
- Make sure that the Target Raster (output location) is correct. If not, click the browse button and navigate to the proper location.
- Click the Mosaic Operator drop-down arrow and choose the rule for overlapping areas if you are loading more than one raster dataset (mosaicking).
- Click the Mosaic Colormap Mode drop-down arrow and choose the rule for dealing with color maps if you are loading raster datasets that have color maps.
- Optionally, type a number for Ignore Background Value to set a background value to ignore.
- Optionally, type a number for NoData Value to set a NoData value.
- Optionally, check the Convert 1 bit data to 8 bit check box.
- Optionally, set the Mosaicking Tolerance.
The mosaicking tolerance controls whether or not resampling of the pixels takes place. If the difference in pixel alignment of the incoming dataset and the target dataset is less than the tolerance, no resampling is performed (instead, a shift is performed). The unit of tolerance is pixels, which have valid values between 0 and 1. To learn more about the mosaicking tolerance, see the Mosaic tool.
- Optionally, choose a Color Matching Method.
This allows you to choose an algorithm to color match the raster dataset being mosaicked together.
- Click OK.
