BCGS Sheet Replacer

From Fmepedia

Created by: Dave Campanas

This transformer replaces the feature with the boundary of the BCGS sheet designated in the feature's Sheet attribute. If no Sheet attribute is present, the feature is passed through untouched. The boundary is returned in the Coordinate System of the source feature.

This transfomer can create 1:20000, 1:10000 and 1:5000 BCGS sheets. The sheet definition must conform to the BCGS specification for those scales.

Examples:

     1:200000  -  92G.087
     1:100000  -  92G.046.2
     1:5000    -  104I.056.4.2

The Segment parameter controls the number of points interpolated along the upper and lower edges to define the sheet curvature when projected.
