[Qgis-user] Trouble projecting on the fly

[Sharon Selvaggio]

Still struggling.... I am attaching the info from the prj file and the 
extent info from the metadata for each shapefile:

I noticed that the PROJCS is labeled as "Custom"...could that be 
confusing QGIS?

Or is it because one is a projected CRS and one is a geographic CRS?

*_or_state_boundary.prj_*
PROJCS["Custom",
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",1312335.958],
PARAMETER["False_Northing",0.0],
PARAMETER["Central_Meridian",-120.5],
PARAMETER["Standard_Parallel_1",43.0],
PARAMETER["Standard_Parallel_2",45.5],
PARAMETER["Central_Parallel",41.75],
UNIT["Foot",0.3048]]

xMin,yMin 183871.74,88600.9 : xMax,yMax 2345213.24,1675042.97



*_CKUWR.prj_*
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]]

xMin,yMin -123.522,43.356 : xMax,yMax -121.714,45.4562


Help very much appreciated.
