With ArcGIS Image Analyst, you can perform complex analysis on multidimensional raster data to explore scientific trends and anomalies. Multidimensional data represents geospatial data captured at multiple times and multiple depths or heights. These data types are commonly used in atmospheric, oceanographic, and earth sciences. Multidimensional raster data can be captured by satellite observations where data is collected at certain time intervals or generated from numerical models where data is aggregated, interpolated, or simulated from other data sources.
For more information about multidimensional data, see An overview of multidimensional raster data.
Some of the multidimensional analysis tools are also available with the Spatial Analyst extension. For more information, see An overview of the Multidimensional Analysis tools in Spatial Analyst.
The Multidimensional tab, enabled for a multidimensional raster layer or a multidimensional mosaic layer, provides tools and functionality to work with multidimensional raster data.
Not all functionality on the tab requires the Image Analyst extension. Tools in the Multidimension toolbox do not require an additional extension license.
Multidimensional Extent group
Use the Multidimensional Extent group to limit the variables, dimension extent, and area of interest you want to view and process for the multidimensional layer selected in the Contents pane. Select the variable or variables to view in the Variables drop-down list, and use the Area of Interest drop-down menu to limit the spatial extent of the layer you are viewing. Use the Start and End values to limit the dimension extents.
The extent values are reflected in geoprocessing. For example, if you choose to view two out of four possible variables, and you select a six-month period from five years of data, any geoprocessing tool that references the active multidimensional layer is limited to processing the two variables across six months. Additionally, the multidimensional extent is reflected in the time slider and range slider for the active layer.
More options for defining the multidimensional extent are available using the Multidimensional Raster function, located in the Data Management Group.
Current Display Slice group
Use the Current Display Slice group to change the slice you are viewing in the map. You can also animate slices along a dimension using the Play Slices Along button . The slices are limited by the extents set in the Multidimensional Extent group.
The Analysis group provides quick access to a number of tools and functions for processing your multidimensional data. Click the Temporal Profile button to open a new temporal profile chart for the multidimensional raster layer. Click the icons in the analysis gallery to open geoprocessing tools to analyze your multidimensional raster. Use the Summary Statistics gallery to calculate one of many summary statistics options, generating a new temporary layer on your map.
Data Management group
Use the Data Management drop-down menu to choose from a list of geoprocessing tools that will help you manage or create multidimensional data. For example, use the Subset tool to create a new multidimensional raster that is a subset of your current layer.
Multidimensional analysis geoprocessing tools
In addition to the geoprocessing tools accessible from the Data Management tab, a suite of multidimensional geoprocessing tools is available in the Multidimensional Analysis toolbox. These multidimensional tools extend the functionality of the tools in the Multidimension toolbox by providing scientific analysis of multidimensional data.
