Lines between points at high latitudes do not seem to follow great circle in ArcGlobe

Discussion created by joosthoek on Apr 19, 2012
Dear all,

I made a polygon shapefile consisting of 20 triangle polygons (geodesic grid). See the attachment zip file. Each polygon should be the same size and all 20 together cover the globe.

When I look at the shapefile in ArcGlobe at high latitudes the triangle's become rounded and do not seem to follow a great circle.

I would like to do things like intersections, and I noticed that this is not only a visualization issue. I tried to select the triangle polygon overlaying a certain point and the wrong polygon is selected.

Is this solvable or is this maybe a bug?

Thanks in advance,

Jelmer
