Hello Piero, You may have to adjust the coordinates to 'saddle' the IDL. For example, a rectangle with the coordinates:
170, 10 -------+------ -170, 10 | | | | | | | IDL | | | | | | | | | | 170, -10 ------+------ -170, -10 May extend the "wrong way" around the globe. If you manually adjust the coordinates so they are all on the same side of the IDL, it will probably work: -190, 10 -------------- -170, 10 | | | | | | | | | | | | -190, -10 ------------- -170, -10 or: 170, 10 -------------- 190, 10 | | | | | | | | | | | | 170, -10 ------------- 190, -10 Notice that in the last two examples, the X coordinates are either all positive, or all negative. I have found this to work quite well; you can even extend this to keep adding features to 'globes' that are beyond -180. There is one thing to be wary of, though: when you do cross the date line, the entire geometry will jump to the left or right by 1 globe circumference. I don't have a workaround for that, but you can trick OL by adding features to the neighboring 'globes'. -z On Tue, Jul 27, 2010 at 7:03 AM, Piero Campa <piero.ca...@gmail.com> wrote: > > Hi all, > I'm drawing polygon over a Google base layer. > > Even though I set wrapDateLine to true in the Google base layer, the Vector > layer AND the temporary layer created by the RegularPolygon handler, still > when I draw a polygon I cannot cross the IDL. > > Any idea guys? > Thank you, > Piero > > -- > View this message in context: http://osgeo-org.1803224.n2.nabble.com/International-date-line-and-bounds-tp2541265p5341698.html > Sent from the OpenLayers Users mailing list archive at Nabble.com. > _______________________________________________ > Users mailing list > Users@openlayers.org > http://openlayers.org/mailman/listinfo/users -- David Zwarg Software Developer at Azavea (formerly Avencia) (215) 701-7718 dzw...@azavea.com http://www.azavea.com/
