Similar to how XYD raster layers are rasters that vary with direction, there can be raster layers which vary with height or height and direction and so on. Multi-dimensional rasters can vary with height, date/time, direction or label and any mixture of those (as well as of course X and Y coordinate).
Multi-dimension raster layers can be output by various Openwind processes but can also be assembled by users. First, create a new folder layer then add as children the layers which you want to combine into a higher dimensional object. Then right-click on the folder layer and choose “Create Multi-Dimensional Raster”.
In order to make a multi-height raster, the user must specify the height of each raster and then Openwind will assemble the resulting raster in the ascending height order. The same applies to directions although for directions the directions must be zero-based and consecutive.
When combining raster layers or multi-dimensional raster layers into time-queryable objects, multiple time-query objects can be used for each layer. The last layer in each time-queryable object should be for all dates, all times as it acts as the default case.
The order in which layers can be combined is direction, then height then time. For raster layers to be combined together they must have exactly the same X and Y coordinates. For directional layers to be combined they must contain the same coordinates and the same number of directions. For multi-height layers to be combined (into a time-queryable layer), they must contain the same heights.
Time-queryable layers cannot be combined into higher dimensional layers.
