\begin{abstract}
We have surveyed the Sgr A region (roughly $-12\arcmin$\  to
$+18\arcmin$\  in $l$\  and $-12\arcmin$\  to 
$+3\arcmin$\ in $b$), including the Radio Arc, in the 110-GHz
lines of C$^{18}$O ($J=1-0$) and HNCO ($J_{kk'}=5_{05}-4_{04}$) using
the SEST. We have observed 554 positions with a grid spacing of
$45\arcsec$. The observational data are presented in form of $l-b$,
$l-v$\  and $b-v$\ maps, recently published in A\&AS 113,
257. Observations of selected regions in the Galactic Centre in the
220-GHz C$^{18}$O ($J=2-1$)\ line have also begun and the
Circumnuclear Disk has been mapped with the SEST in the 268-GHz
HCO$^{+}$\ ($J=3-2$) line with a grid spacing of $10\arcsec$. Future
mapping programs are being planned in the 119-GHz O$_{2}$\  line, as
well as in submillimetre lines of O$_{2}$\  (487-GHz) and  H$_{2}$O
(557-GHz), using the 1.1-m Odin satellite telescope, which has a
launch date in the fall of 1997. The Odin satellite is a Swedish 
project in collaboration with Canada, Finland and France.
