Claim One:
1. A method for conflict detection and avoidance of spatial entity element annotations, the method comprising: providing a computer; causing the computer to perform; transforming, according to a preset view control parameter, original coordinates of spatial data of an original element into view coordinates in a view window; rasterizing, in the view window, an element which the spatial entity element annotations avoid, wherein the element includes annotations which shall be avoided; and analyzing an annotation of the original element, which is one of the spatial entity element annotations, according to the view coordinates, and determining a plane annotation region that satisfies a preset display condition and corresponds to the annotation as an annotation display region for the annotation, wherein determining a plane annotation region that satisfies a preset display condition is performed according to the rasterized element, wherein the rasterized element includes rasterized annotations which shall be avoided.
