Spatial Analyst - Working Across The 180 Degree Line

Discussion created by andrewbprice on Mar 21, 2013
Hi,

I'm using the Kernel Density tool in the Spatial Analyst toolbox. I have a large number of points that are split across both sides the 180 degree line. When I run the tool the resulting raster appears fine for the most part, but it seems as though points on one side of the 180 degree line are not recognised as being 'near' a point on the other side, even though they may in reality be next to each other.

In other words, clusters of points that lie across the 180 degree line appear as two seperate clusters, instead of one.

Is there any way of getting Spatial Analyst to look across the line for points, instead of stopping it's search there? I've tried numerous projections, all with the same result.

Thanks
