[FWTools] using a custom coordinate system within gdalwarp

[Mark Volz]

Hello,

I am trying to convert a mrsid file to a geotiff using gdalwarp.  The to
projection is in county coordinates, so it does not have an EPSG code.  How
can I use a ESRI.prj file with gdalwarp?

gdalwarp -s_srs EPSG:26914 -t_srs "my ESRI Projection" -r cubic ortho_1-
1_1n_s_mn117_2010_1.sid FSA2010.GTiff

Also,

If it works better I have the projection information from Mapserver

	Projection  #Pipestone County Coordinates
        	"proj=lcc"
   	    	'lat_1=43.88333333333334'
		'lat_2=44.15'
	    	'lat_0=43.849166666666667'
	    	'lon_0=-96.25000000000001'
	    	'x_0=152400.3048006096'
	    	'y_0=30480.06096012192'
	    	'a=6378670.401'
	    	'b=6357283.927'
     		"units=ft"
        	"no_defs"
   	END #projection

Thanks
