[TCMUG] Datum Transform Dakota Cnty => NAD83?

[David Fawcett]

I am projecting some of the new awesomely open Dakota County spatial data
from the Dakota County custom SRS to EPSG 26915.

It looks like a datum transform is in order, but I am having a hard time
coming up with one.  Any suggestions?

Here is the .prj file contents for the SRS:

PROJCS["MN_Dakota_Lambert_Conformal_Conic",GEOGCS["GCS_MN_Dakota",DATUM["D_MN_Dakota",SPHEROID["MN_Dakota",6378421.989,298.2572133677353]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Lambert_Conformal_Conic"],PARAMETER["False_Easting",500000.0],PARAMETER["False_Northing",100000.0],PARAMETER["Central_Meridian",-93.31666666666666],PARAMETER["Standard_Parallel_1",44.51666666666667],PARAMETER["Standard_Parallel_2",44.91666666666666],PARAMETER["Latitude_Of_Origin",44.47194444444445],UNIT["Foot_US",0.3048006096012192]]

For reference, here is the .prj for 26915:

PROJCS["NAD_1983_UTM_Zone_15N",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",-93],PARAMETER["scale_factor",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",0],UNIT["Meter",1]]


It looks like they use the same spheroid.
