Hi Jed,
I'm look for this projection on spatialreference.org. I found this one:
http://spatialreference.org/ref/sr-org/7670/
Does this one the same or close to the ESRI one?
Best regards,
Dmitry

Dear GDAL gurus,
I have some scanned maps in the “Times" projection that I would like to
orthorectify using gdalwarp and other GDAL tools. It appears that this projection is
not supported in the version of proj4/GDAL that I have, though it seems to be
included in most ESRI software
(http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//003r00000045000000).
Would anyone happen to know of free software I could use to rectify scanned
maps in the Times projection? Alternatively, I could try programming the
projection into proj4 myself, though I’ve never done this before. Snyder
provides the formulas for the forward projection in his book “Flattening the
Earth…” (pg. 213). If I would program a new projection in proj4, are there
particular issues I need to be aware of?
Many thanks in advance for your help!
Jed Kaplan
