Question

Rubbersheet transformer has no effect on Observed geometry

I am transforming a dataset using the RubberSheeter, but it is having no effect on the Observed data. The control dataset is 11,600 polylines, in a shapefile, and are an average of 1,150,000 feet long. I have successfully used this transformer before, but the control geometries have been much shorter in length.

Distance Exponent: 2.0

Max Distance: 0

Max Number of Influencing Vectors: 0

No constraints. The Control and Observed are the same coordinate systems.

The features exiting from the Corrected port are exactly the same as the original source and I cannot figure out what the issue is.

Any help appreciated.

Hi @chappell,

Please check the orientation of the Control vectors to ensure that the start point of the vector is within the Observed data. If the vectors are reversed, the Distance Exponent would keep them from having any effect on the rubbersheeting.

Hey @DaveAtSafe,

The first image shows the direction (only displayed one, but all point in the same direction).

The second image shows that the start points are within the observed data.
