Hi Ian
You should be able to get this by querying the objects MBR() ie Minumum
bounded rectangle.
eg select ObjectGeography(obj,1) "Min_X",ObjectGeography(obj,2)
"Min_Y",ObjectGeography(obj,3) "Max_X",ObjectGeography(obj,4) "Max_Y" from
My_table
If you have some deleted objects in your table ei
Greetings,
It has been sometime since I have used MI4.5, but I do have a question about

select * from query1 where rowid mod 2 = 1
I believe this approach to be better because it can be used to get every Xth

Hello all, I would like to know if anyone has the specs for creating
gnomonic projections in MapInfo. My quick perusal of MI 5.0 projections

for plotting great circles. I know it's possible too that MI
can't/doesn't support t
