Application ID: 13520673

Base Claim:
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.

Claim 5:
5. The method according to claim 1 , wherein the analyzing an annotation of the original element 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 comprise: generating the plane annotation region corresponding to the annotation of the original element; and judging whether the plane annotation region satisfies the preset display condition, and if so, determining the plane annotation region is the annotation display region, otherwise, determining the plane annotation region is not the annotation display region.
