[GRASS-user] Odd vector point placement

All,

I have a set of vector points captured as decimal latitude / longitude, in a Mysql database.

I am looking at a point which in the Map display is showing in the wrong place. In the database field, the point is captured as being at -21.133, 149.1833.
The point displays at the correct latitude, but at longitude 153.81 (at least if I look at the map display with the mouse pointer!).

If I query the point, it shows the right lat/long, and the hundreds of other points in the database seem to be coming up with the right spots.

Any thoughts?

Hi Richard,

most GIS systems want the coordinates to be in x,y or
longitude-latitude order. I do not think that your (-21, 149)
coordinate pair is in the correct order -- could this be a source of
the problems?

cheers,

Dylan

which version of GRASS? If 6.3, when was the code checked out of CVS?
