Re: [mapguide-users] Wisconsin County Coordinate Systems Error on Transform

[Flipper]

In a follow up note, This turned out (in my case) to be Strictly Because
proj4js cannot parse County Coordinate codes for Either Minnesota or
Wisconsin, there is something it does not like at all. This will need to be
addressed if a new fusion viewer on a newer proj4js is to be utilized

Here is an example: In Mapguide this System will not parse out in proj4js
PROJCS["MowerMN-F",GEOGCS["LL83",DATUM["NAD83",SPHEROID["GRS1980",6378137.000,298.25722210]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Lambert
Conformal Conic, Minnesota DOT
Variation"],PARAMETER["false_easting",50.000],PARAMETER["false_northing",10.000],PARAMETER["central_meridian",-93.95],PARAMETER["latitude_of_origin",43.50],PARAMETER["standard_parallel_1",43.80],PARAMETER["standard_parallel_2",43.57],PARAMETER["Average
Elevation (system unit)",1260.],UNIT["Foot_US",0.30480060960122]]

This is from a Minnesota website I found
PROJCS["NAD_1983_HARN_Adj_MN_Mower_Feet",GEOGCS["GCS_NAD_1983_HARN_Adj_MN_Mower",DATUM["D_NAD_1983_HARN_Adj_MN_Mower",SPHEROID["S_GRS_1980_Adj_MN_Mower",6378521.049,298.2572221008827]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Lambert_Conformal_Conic"],PARAMETER["False_Easting",50.0],PARAMETER["False_Northing",10.0],PARAMETER["Central_Meridian",-93.95],PARAMETER["Standard_Parallel_1",43.57],PARAMETER["Standard_Parallel_2",43.8],PARAMETER["Latitude_Of_Origin",43.5],UNIT["Foot_US",0.3048006096012192]]

This parses out fine in proj4js, however Meastro and Mapguide Studio will
not reproject to the new coordinate system from the old MG coordinate system
so Every layer in the map also needs a coordinate system over-ride (VERY
tedious)

Strangely it works in mapguide rest. I dont understand why the mapguide site
will not reproject. That makes no sense.
In a side note Proj4js does not understand the wkt so it can't be used in
open layers 3 either. I am able to hard code a wkt it can recognize into the
map and layers that mapguide and proj4js is OK with. But that's not a
workaround that should be necessary

Will try that Monday..if I force over-ride the coordinate system and known
extents mapguide does not do projection. So I rules out maestro

You can confirm if it's a MapGuide-level problem by doing the same
transformation with the same coordinates and coordinate systems through
mapguide-rest and seeing if it fails too.

Re: [mapguide-users] Wisconsin County Coordinate Systems Error on Transform

[Scott Hameister]

It is Every Wisconsin County Code. In Maestro you can select USA Wisconsin
then pick a County Coordinate..You can't project anything From or Into any
of them I have tested.

I Have tested Ashland COunty, Vilas County, and  Florence County
Florence County when selected for example uses:
WKT:
PROJCS["HARN/WI.FlorenceWI-F",GEOGCS["HARN/WI.LL",DATUM["HARN/WI",SPHEROID["GRS1980",6378137.000,298.25722210],TOWGS84[0.,0.,0.,0.00,0.00,0.00,0.]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse
Mercator, Wisconsin County
Variation"],PARAMETER["false_easting",438000.000],PARAMETER["false_northing",0.000],PARAMETER["scale_factor",0.9350],PARAMETER["central_meridian",-88.141667],PARAMETER["latitude_of_origin",45.438889],PARAMETER["Average
Geoid Height (meters)",-32.8700],PARAMETER["Average Elevation (system
unit)",1400.],UNIT["Foot_US",0.30480060960122]]

or
WKT: 
PROJCS["FlorenceWI-F",GEOGCS["LL-HPGN",DATUM["HPGN",SPHEROID["GRS1980",6378137.000,298.25722210]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse
Mercator, Wisconsin County
Variation"],PARAMETER["false_easting",438000.000],PARAMETER["false_northing",0.000],PARAMETER["scale_factor",0.9350],PARAMETER["central_meridian",-88.141667],PARAMETER["latitude_of_origin",45.438889],PARAMETER["Average
Geoid Height (meters)",-32.8700],PARAMETER["Average Elevation (system
unit)",1400.],UNIT["Foot_US",0.30480060960122]]

Depending on which one you pick...Neither works forward or backward
projection.

Can you share the PROJ code you are using for Wisconsin?
