Map result

Below is the result of my map experiments: the track of a flight with Ken flying practice approaches at Salinas overlayed on top of two approach charts and the Google Terrain base layer. It’s a bit of a jumble.


  • Transparent brown line: flight track
  • Black scratchy lines: approach chart
  • Brown terrain contours: approach chart
  • Green terrain: Google maps

What I’m really trying to highlight is the juxtaposition of the GPS track to the black approach path on the procedure plate. The other stuff is context, or noise. It’s less confusing if you only draw one approach chart, not two. Making parts of the approach plate transparent is a big help too; it’d be nice to eliminate the terrain, etc entirely. Maybe just let the black lines come through.
