Hi Scott! Although I'm unsure what you mean by 'gridding' I would like to point out a possible explanation.
Behind the scene, Mapinfo uses its own grid which simply put can hold one, and only one, coordinate pair per cell. The grid has a finite number of cells and the absolute size of the cells depend on the size of the geographic coverage (i e bounds) So, the smaller the bounds, the smaller the cell size = a higher resolution. I seem to remember that a lat/long earth coverage roughly equals a cell size of 1" but that seems much smaller than the cell size you mentioned. On the other hand, I have received 'converted' MIF files where the bounds could incorporate the ISS and the moon as well, so you never know.

I am currently gridding up some multibeam sonar data with MapInfo 7.0. I have done this before with some success. The problem that I am encountering is that I have data that was collected at a resolution of 2.5 metres. So, I have a huge point set with all of the points 2.5 metres apart. When I try to grid this data at a 2.5m cell size I get an error stating "Out of Bounds- CELL SIZE must be between 0.00472 and 0.484" (i.e. 4.7m minimum cell size). Why is the minimum cell size I can create almost double that of the source data? Any help is appreciated, Scott --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 14396
