Georeferenced instrument procedures and airport diagrams

Postby jlmcgraw » Thu Nov 27, 2014 2:25 am

All,
I'm making available a snapshot of the data from my project to create a georeferencing database for all United States FAA provided Instrument Approach Procedures and Airport Diagrams

The vast majority of these were automatically referenced, the rest were done by hand and then all were manually checked. This data is for the 1412 cycle so it is current as of this posting. I'll try to upload new releases from time to time but I can't make any promises.

This data is free for non-commercial use only, please do not use it commercially without contacting me.

If you have any comments or questions please contact me directly: jlmcgraw@gmail.com

Use this data at your own risk, it is not guaranteed in any way (but have fun with it nonetheless)!

The sqlite database of dtpp info and the 6 parameters for the affine transformation of each plate (numbers are based on PDF->PNG rasterization @ 300dpi)

An archive of the world files for all plates, grouped by airport, created from the above database. You'll need to provide the 300dpi PDF->PNG rasters yourself. Load into QGIS to see how they look!

This is just the georeferencing data for Airport Diagrams and Instrument Approach Procedures.

It's only useful if you are wanting to display these charts in relation to the real world or your position on one of them, for example in a Moving Map or EFB application (or Flight Gear)
