Dear Barbara,
one of my Chinese master students, Li Hui MSc, told me:
As I know:
In China, the basical scale map include:1:5000, 1:10T, 1:25T
,1:50T，1:100T，1:250T，1:500T，1:1000T
And, if the scale is bigger than 500T, uses Gauss-Kruger projection
if smaller than 500T, uses Lambert Conformal Conic projection,
and smaller than 500T on the sea, uses Mercator projection.
Regards
Dr. Franz-Josef Behr

Hi
Does anyone have the details for datums and projections used in Chinese
maps? I have downloaded some of the CIESIN data and it's in Lambert
Conformal Conic projection. The readme file includes the following:
COORDINATE SYSTEM
All coverages are in LAMBERT CONFORMAL CONIC PROJECTION with
two standard parallel latitudes: 25.00N and 47.00N. The central meridian is
110.00E and the latitude of projection's origin is 10.00N. The units are
meters.
If anyone has the details to edit the mapinfo.prj file it would be very
greatly appreciated.
Thanks!
Barbara Carroll
