[Mapserver-users] CGI: Projecting to polar aspects problems

[Martin Weinelt]

Hi list,

projecting point shapefiles with geographic co-ordinates to polar 
aspect projections (such as Lambert Azimuthal in polar aspect or 
Polar Strereographic) result in map images missing data points 
'close' to the pole(s), especially when the pole(s) are the center of 
the image. I have tested this effect for LAEA and STERE. This also 
affects long/lat GRID layers.

Currently I project the shapefiles in advance to avoid the effect, but 
in the long run this is not an option for me. What are practical 
solutions? 

1. Use CGI with dynamically projected shapefiles?
2. Move over the entire installation to MapScript ? 

Thanks, Martin
