Updated US Sectionals

The US sectional charts on my website (in CMR format for SeeYou and
georeferenced TIFF format for GoogleEarth, Global Mapper, etc.) have
been updated to the most recent versions. Moving forward, I plan to
issue new updates every charting cycle, so that the charts will always
be current.

Some have asked how these are different from the charts you can
download from the FAA. The answer is that the format that the FAA
provides can't be used directly with SeeYou -- the charts have to be
reprojected and reformatted first. I also trim the edge material on
both the CMR and TIFF format versions such that the charts tile
together seamlessly. This is a big deal if you happen to fly near the
border areas.

My website can be found at http://www.soaringdata.info. In addition
to the sectional charts, you can find current US airspace and airport
data in formats commonly used by popular glide computer and task
planning software. All of the materials on my site are free, and
freely redistributable.

Happy Downloading!
