This was posted in a sailing ng but hasn't had a definitive answer
yet. Here may be a more appropriate place:

"Apologies if it's been done already but I can't find the answer.
What's the furthest distance you can sail in a straight line (great
circle)? "

And I'd like to add a similar question about land distance.

TIA

Hi,
I have map images with the Albers Equal Area Conic Projection and
several known (cartesian) latitude and longitude (decimal degrees)
points I would like to plot on the image. How do I convert these
cartesian decimal degrees into cartesian pixels for plotting using
simple image manipulation libraries? Here is what I know:

Image Projection: Albers Equal Area
False Easting: 0.0
False Northing: 0.0
Central Meridian: -95.0
Standard Parallel 1 : 29.5
Standard Parallel 2 : 45.0
Latitude of Origin : 0.00
Image width (pixels) : 504px
Image height (pixels) : 360px

I've been looking at:
http://mathworld.wolfram.com/AlbersEqual-AreaConicProjection.html

But I'm not sure how to apply the formulas to do what I need. Any help
is greatly appreciated.

what is a good Free(?0 Open source(?) package or collection of programs
for producting maps. Mostly strip maps.

Want to do something like scan/take various images and digitise routes off
them.

I'm dealing with GRIB data and it is projected as a Lambert Conformal
projection. the grids in the data are spaced by 32 km. The question I
have is how can I convert this 32 km distance into a change of
latitude and longitude?
