Dear Viktoria, Have you tried to input longitudes modulo 360°, since -180=360 ? Does the map allow for that ? Dominique Viktoria Kahui a écrit:
Thanks for your reply. I am working on a case study on the east coast of New Zealand. I agree that the coordinates should be between -180 and 180, the problem is when I type Long min -171 and Long max 170 ISIS takes the area to the left of New Zealand all around the world. If I swap it and type Long min 170 and Long max -171 (which should be the right way to do it) then ISIS does not recognise this. I think there might be a problem with defining an area that stretches ACROSS the -180 longitude line. Maybe a programming error?
Thanks Viktoria

Hi Viktoria,
I don't know which case study you are working on but longitude must be defined between -180 to 180. And you should restrict the area to your case study boundaries.
I Hope you will succeed in creating your case study area,
Cheers,
Youen
Viktoria Kahui a e'crit:
Hi
I am a new user and I am trying to input coordinates for the fishery area boundaries (5.2.2 Fishery area characteristics). I am inputting longitude coordinates that straddle the time line and experience problems when trying to input for example Min.Lon. 170, Max.Lon -171. My grid disappears. If, however, I input Min.Lon. 170 and Max.Lon 189 it works and I get the area of grids covered I want. The problem then is that when I try to define the cells in the next command (5.2.3 Cells), ISIS doesn¡¯t let me click on any of the cells beyond lon 180.
Does anyone know what I am doing wrong?
Thanks Viktoria
