Implement a 'Post Processing' parameter in the 'Apply' tool to straighten parcel lines after a least squares adjustment
Our organizations utilizes the 'Weighted Least Squares Adjustment' tool, as well as the 'Apply' tool to apply the results to the parcel fabric. We are finding that in certain areas where we have a lot of 'point to edge' snapping, the results of the LSA are not ideal. After applying the LSA results, there can be a fair bit of warping so that the lines are no longer straight:
From what we understand, this is a consequence of the “direction set” method for the LSA. Direction sets are created per record (plan). The new plan being integrated into our parcel fabric does not contain constraints for each of the points along the line, so the only measurements defining the original points is the underlying plan of lower accuracy.
In the ArcMap world, this would have been straightened out with the 'Line Point Post Processing' parameter rolled into the LSA. In ArcGIS Pro, there is no such post processing parameter for point to edge scenarios. Our current workaround is to manually post-process the data by running an align features process where we draw a straight line from one end of the lots to the other and align everything to it. This can be time consuming, and we would like to request that a post processing parameter to straighten point to edge scenarios be implemented in the Apply tool in ArcGIS Pro - it could be an optional parameter, so each organization can choose the option that works best for them.
