G2_pixelInstruments xTransect requiring single Y-coordinate #37
In G2_pixelInstruments, pixel instruments for xTransect and yTransect can be created. However, the y-coordinate and x-coordinate, respectively, for these must be a single constant value. For grids that have a localAngle rotation not aligned perfectly to the x/y grid or for beaches/coasts that aren't perfectly straight, this function cannot be utilized and one must go back to the old pixel toolbox way of creating pixel instruments.
example shown here for Isla Verde, Puerto Rico. Desired rotation angle causes beach/shoreline/coast not to be aligned with grid. Coast is slightly curved as well.
