I got it working!  The solution was to re-run the ogr2ogr command like this:

ogr2ogr -t_srs EPSG:26719 -f "ESRI Shapefile" temp rrnh.e00

My question is... if tools like ogrinfo can read all the projection data out of 
the file, why can't mapserver do this on the fly?  Or is it just the case where 
we don't want to have to do all the work every time for performance reasons?

Thanks for everyone's help!

So, I think the answer to your question is, no they're not in the same projection.  What 
do I need to do to get mapserver to translate between the two? Seems to me that mapserver 
should be able to read the information out of the files (like ogrinfo and gdalinfo do) 
and do the "right thing". I admit this might be a total misunderstanding on my 
part... still learning about mapserver's capabilities.


Yes, epsg:26719 refers to UTM zone 19; the NH state plane is, I think,
somewhat different.

The ARC.prj file generated by ogr2ogr contains this (expanded for clarity):

PROJCS[
  "NAD83_New_Hampshire",
  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",42.5],
  PARAMETER["central_meridian",-71.67],
  PARAMETER["scale_factor",0.7],
  PARAMETER["false_easting",984250],
  PARAMETER["false_northing",0],
  UNIT["Foot_US",0.30480060960121924]
  ]

epsg:3437 would use

PROJECTION
  "proj=tmerc"
  "lat_0=42.5"
  "lon_0=-71.67"
  "k=0.7"
  "x_0=30.0"
  "y_0=0"
  "ellps=GRS80"
  "datum=NAD83"
  "units=us-ft"
  end

but because the false_easting in the prj file is not 30,
it looks to me like you should try this:

PROJECTION
  "proj=tmerc"
  "lat_0=42.5"
  "lon_0=-71.67"
  "k=0.7"
  "x_0=984250.0"
  "y_0=0"
  "ellps=GRS80"
  "datum=NAD83"
  "units=us-ft"
  end

I wouldn't claim to be expert in any of this, so I welcome a review
by someone more familiar with these projection parameters.

Jon,

The rr data are in NH state plane coordinates--are the other data you
are using in the same projection?

Thanks Peter,

I had to specify the raster layer as:

LAYER
  NAME "usgs"
  TYPE RASTER
  STATUS on
  DATA o43071a4.tif
  PROJECTION
"init=epsg:26719"
  END
END

Hi David,

The layer name is explicitly called out in the URL; changing it to DEFAULT has 
no effect.

You haven't defined the LAYER's PROJECTION (we really should enhance mapserver 
to read .prj files!)
