A method for detecting and avoiding the conflicts of space entity element annotations is disclosed, which includes: according to the predefined view control parameters, the original coordinates of an original element's spacial data are transformed into the view coordinates of a view window; the element where an annotation needs to be avoided is rasterized in the view window; the annotation of the original element is analyzed according to the view coordinates, and the planar annotation area, corresponding to the annotation and consistent with the predefined display conditions, is determined as the annotation display area of the annotation. Also an apparatus for detecting and avoiding the conflicts of space entity element annotations is disclosed. In the disclosed method for detecting and avoiding the conflicts of space entity element annotations, the spacial relationship of each view coordinate can be embodied visually in the view window and analyzed in the window so that the analysis is simplified and the low display effectiveness caused by the discarding of the annotations that can be displayed is avoided. |
