Rotate Data

The objective of the Rotate Data in 2D tab, available in the property panel of the Data Loader Component, is to deal with 2D rotation in Datamine block models. When importing rotated Datamine block models, Supervisor imports the XC, YC, ZC columns which are local rotated world coordinates. By consequence, block model data cannot be compared to data located in real world, like drillhole data for example and then apply a model validation or KNA.

• Clicking on the grid loader, angle and X/Y/Z translation fields show you if the original file was rotated or not. They specify which transformations should be applied to convert any data in the real coordinate system into the local coordinate system. The angle is expressed as an azimuth.

• When reaching the properties of your drillhole data, by selecting your block model in the Get transformation settings by selecting a data loader field, you will automatically define the angle and the translation along X, Y and Z to apply to your drillholes to be in the same local coordinates as your block model.

Note: It is possible to apply a rotation to any type of data but applying such a transformation to a block model can lead to inconsistencies. The transformation of the coordinates associated with each block center will be correct and won't cause issues for most calculations. However, the visualisation as a grid may be incorrect, since the blocks themselves won't be rotated.

See Configure the Rotate Data in 2D Tab to more details about the different parameters.
