サマリー
Exports a 3D geostatistical layer created using the Empirical Bayesian Kriging 3D tool to a multidimensional Cloud Raster Format (*.crf file) raster dataset. Tools in the Multidimensional Analysis toolset of the Image Analyst toolbox are designed to work directly on multidimensional rasters and can identify the 3D nature of the data.
3D geostatistical layers store continuous 3D interpolation results and appear as 2D horizontal slices at a given elevation. The current elevation can be changed with the range slider, and the layer will calculate and render the predicted values of the new elevation. Rasters of interpolated predictions can be extracted at any elevation using the GA Layer To Rasters tool. The GA Layer 3D To Multidimensional Raster tool automates the process of extracting rasters at multiple elevations and stores them as a multidimensional raster dataset.
使用法
The Input 3D geostatistical layer must be created using Empirical Bayesian Kriging 3D.
You can provide the desired elevations in either of the following ways:
- Provide elevation values using an iterator—Leave the Enter explicit elevation values parameter unchecked, and provide values to the Minimum elevation, Maximum elevation, and Elevation interval parameters. The iteration will start at the minimum and increase by the interval up to the maximum. For example, if you provide a minimum elevation of 0, a maximum of 100, and an interval of 20, the output will have six elevations: 0, 20, 40, 60, 80, and 100.
- Provide explicit elevation values—Check the Enter explicit elevation values parameter, and provide the desired elevations in the Elevation values parameter.
If the Elevation interval provided does not evenly divide the elevation range (Maximum elevation minus Minimum elevation), one elevation will be used that exceeds the maximum elevation. For example, if you provide a minimum elevation of 10, a maximum elevation of 80, and an elevation interval of 20, the output will have five elevations: 10, 30, 50, 70, and 90.
The default raster cell size of the Output multidimensional raster dataset parameter is the smaller of the output extent of the x and y dimensions, divided by 100. The default number of elevation slices is 10. This will create a multidimensional raster with an x and y resolution that is at least 10 times larger than the z-resolution. Consideration should be given to these values, particularly if you want approximately the same resolution in all three dimensions. Increasing the cell size or increasing the number of elevation slices will result in outputs that are closer to the same resolution in all dimensions.
The execution time of the tool is approximately proportional to the number of overall predictions that are required, and each raster cell of each elevation requires the calculation of a predicted value. By default, the execution time of the tool is approximately 60 percent longer than exporting a single elevation slice using the default options of the GA Layer To Rasters tool. Including Additional output types will not significantly increase the execution time because multiple output types can be predicted simultaneously.
If any Additional output types are provided, the output raster will be a multivariate multidimensional raster dataset with a different variable for each output type.
All tools in the Multidimensional Analysis toolset of the Image Analyst toolbox will have increased performance if transposes are built on the multidimensional raster. You can use the Build multidimensional transpose parameter to build them automatically, but this will increase the execution time of the tool. You can also use the Build Multidimensional Transpose tool to build transposes later.
