I'm working with census shapefiles. The .prj file has the following contents:
PROJCS"NAD_1983_StatePlane_Connecticut_FIPS_0600_Feet",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Lambert_Conformal_Conic"],PARAMETER["False_Easting",999999.999996],PARAMETER["False_Northing",499999.999998],PARAMETER["Central_Meridian",-72.75],PARAMETER["Standard_Parallel_1",41.2],PARAMETER["Standard_Parallel_2",41.86666666666667],PARAMETER["Latitude_Of_Origin",40.83333333333334],UNIT["Foot_US",0.30480060960121924]

I want to transform this to a Mercator projection. To do this I'm extracting the GEOGCS definition from the above, creating an IGeographicCoordinateSystem object, and then creating a projected coordinate system. Is this the correct approach when dealing with shapefiles like this? Thanks for any help.
