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
