Hey,

The good news is that Oregon is the last one I need to get working.  The bad news is I do not have it working yet.

Here is the metadata from the .prj that I got from the state:

PROJCS["NAD_1983_Oregon_Statewide_Lambert_Feet_Intl",
GEOGCS["GCS_North_American_1983",
DATUM["D_North_American_1983",
SPHEROID["GRS_1980",6378137.0,298.257222101]],
PRIMEM["Greenwich",0.0],
UNIT["Degree",0.0174532925199433]],
PROJECTION["Lambert_Conformal_Conic"],
PARAMETER["False_Easting",1312335.958005249],
PARAMETER["False_Northing",0.0],
PARAMETER["Central_Meridian",-120.5],
PARAMETER["Standard_Parallel_1",43.0],
PARAMETER["Standard_Parallel_2",45.5],
PARAMETER["Latitude_Of_Origin",41.75],
UNIT["Foot",0.3048]],
VERTCS["NAD_1983",
DATUM["D_North_American_1983",
SPHEROID["GRS_1980",6378137.0,298.257222101]],
PARAMETER["Vertical_Shift",0.0],
PARAMETER["Direction",1.0],

I initialized proj as follows:

proj +proj=lcc +lon_0=-120.5 +lat_0=41.75 +lat_1=43.0 +lat_2=45.5 +x_0=1312335.958005249 +y_0=0.0 +units=ft

I assume something is not right.

In http://www.findlatitudeandlongitude.com/, I picked the Eastern most point in the state, 45.614818, -116.463726, and verified in maps.goole.com.

From the state's shape file, I picked the point touching the bounding box on the Eastern side, 1005007.55709, 1323046.51837 (1,005,007, 1,323,046), so these are the numbers I am expecting from proj.

When I give this to proj, 

-116.463726 45.614818

I get:

5338087.78 1434192.31 (5,338,087 1,434,192)

As you can see, my numbers are not close.

I would be grateful if someone would help me initialize proj correctly.

Thanks,

Rick Graves
