Hi Ashwin: Well that is almost correct, it depends on how the data are setup. Th more accurate statement is that the query can not loop around any of the coordinate bounds. If the prime meridian is one of the longitude limits , than you can not cross it in a request. but if it is not on the boundary than it can be crossed. So if a dataset has longitudes (0,360) you can’t cross it, but if it is (-180,180) you can, but you can’t cross the dateline. -Roy > On Jun 3, 2016, at 8:44 AM, ashwinD12 . <winash12@xxxxxxxxx> wrote: > > Hello, > I had an associate of mine inform me that when an OpenDAP > expression's longitudinal extent spans the prime meridian then we must query > the data on both sides of the prime meridian and join the results.
