 Summary

VECTOR ROTATION AND SHIFTING
Input: any vector layer (point, line, polygon, etc...)
Output: a vector shapefile of the same type as the input
Features:

  • this tool will rotate and/or shift the vector features in the layer, creating a new layer as output
  • you can opt to process selected features only
  • all the attributes in the reference layer are copied to the output layer

Limitations:

  • the reference layers MUST be in a projected coordinate system (this tool will produce biased results if a geographic coordinate system is used)
  • this tool is designed to work with shapefiles, other vector formats have not been tested

 Help

Getting started The vector reference layer must be loaded into ArcMap before starting this tool.

Output shapefile The output of this tool is a shapefile of the same type as the input shapefile.

Rotation There are two components to rotation: a pivot point around which the rotation occurs, and the angle of rotation. The center of rotation in this tool can either be defined manually, or you can select one of several pre-set options (the center of the extent of the vector layer, the SW corner, etc). The angle of rotation is specified in degrees and can range from -360 degrees (anticlockwise rotation) to +360 degrees (clockwise rotation).

Shift Shifting simply moves the vector shapes by a constant x and/or y value. Negative values will move shapes west and south for the x and y axes respectively. Positive values will move shapes east and north for the x and y axes respectively.

Both rotation and shifting If you are combining rotation and shifting it is important to consider which to apply first, because you will get different results depending on whether the rotation or the shift occurs first.
