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...

It is Spring again, and if you haven't done so in awhile it would be a great time to update the airspace and airport databases in your glide computer, PNA, handheld GPS, or desktop planning software in preparation for the upcoming US season. The FAA data for the charting cycle effective March 30,...

US Pilots, With the onset of cooler weather, I've had time to do a tiny project I've been meaning to work on for a long time. Many of you are aware that my website (http://www.soaringdata.info) can produce current US Temporary Flight Restriction airspace files in formats that work with most glide...

Hello All, It is that time of year again. If you haven't done so in awhile, it would be a great time to update the airspace and airport databases in your glide computer, PNA, handheld GPS, or desktop planning software in preparation for the upcoming US season. The FAA data for the charting cycle...

Perhaps it is as good a time as any to announce that I can support the creation of at least a limited number of custom maps for GlidePlan. These are maps that are made from overlapping portions of more than one sectional chart. I have already done a few examples, which can be downloaded at ...

Hello again all, As many of you know, I publish digital US sectional charts in CMR format for SeeYou and JPG format for GoogleEarth on my website at http://www.soaringdata.info. These charts have been reprojected from the original Lambert conformal conic to a rectangular lat/lon projection that...

Has anyone besides me noticed that SeeYou 4 (desktop version) has been released? It's a bit confusing becuase the date next to the link on Naviter's website is shown as 2010 instead of 2011, but it really is a new release. Also, you have to select the SeeYou entry on the Download or Products menu...

Here are a couple of things I've been asked about several times. I thought I would post here for wider distribition: Hint #1 - If your glide computer or PNA can't handle the airspace file for the entire US, consider making a custom extract of a smaller region. Here is how you do it: 1. Go to...
