Hi,

while trying to define a lat/long location with Sphere instead
of WGS84, I found in

src/libes/gis/ellipse.table
# earth as a sphere:
# There is a bug in libes/gis/get_ellipse.c, where a function
# return e=0.0 in any case. So do not use sphere!
# sphere        "Spherical Earth"               a=6370997.000

Is there no/any hope to fix the code (I don't know how...).
It seems that some of my data weren't generated with WGS84,
which may cause distortions when reprojecting to UTM (final
projection).

Any hint is welcome,

 Markus
