Arcgis:Coordinate ranks

2/13/2017來源:經驗技巧人氣:10651

The coordinate accuracy ranks you specify forfeature classes in a geodatabase topology control the movement of featurevertices during validation. The rank helps control how vertices are moved whenthey fall within the cluster tolerance of one another. Vertices within thecluster tolerance of one another are assumed to have the same location and arecolocated (the same coordinate values are assigned for the coordinates thatfall within the cluster tolerance).

 

When different feature classes have a differentcoordinate accuracy, such as when one was collected by survey or differentialGlobal Positioning System (GPS) and another was digitized from a less accuratesource, coordinate ranks can allow you to ensure that reliably placed verticesare the anchor locations toward which less reliable vertices are moved.

 

Typically, the less accurate coordinate is moved tothe location of the more accurate coordinate, or a new location is computed asa weighted average distance between the coordinates in the cluster. In thesecases, the weighted average distance is based on the accuracy ranks of theclustered coordinates.

The location of equally ranked vertices aregeometrically averaged when they are within the cluster tolerance of eachother.

Be sure to assign ranks in the PRoper order. Thefeatures with the highest accuracy get a rank of 1, less accurate features geta rank of 2, and so on.
