.. currentmodule:: globalmapper
.. py:function:: SpatialMBR (GM_LayerHandle_t32 aLayer, GM_SpatialOps_Params_t aParams, GM_FeatureGrouping_t8 aGrouping, str aStr) -> GM_Error_t32

	The **MBR (Minimum Bounding Rectangle)** spatial transform creates a new layer with the smallest axis-aligned bounding box
	that contains the features from *aLayer*. The parameter *aGrouping* can be used to specify whether to make MBRs for
	each feature, each feature group, or one for the entire layer.

	:param GM_LayerHandle_t32 aLayer: Input layer
	:param GM_SpatialOps_Params_t aParams: Parameters
	:param GM_FeatureGrouping_t8 aGrouping: Grouping type
	:param str aStr: The attribute list string; may be an empty string
	:returns: Error Code
	:rtype: GM_Error_t32
