High Altitude Enroute Charts

High Altitude Enroute Charts are used for aircraft navigation above 18,000 feet in the United States.  The charts show the locations of radionavigations aids (VORs, etc.), airports, intersections, airways, etc.  Unlike Sectional Charts, these charts do not show ground topographic and visual navigation features.

These charts have been merged together to create seamless coverage for the entire lower 48 United States and Alaska.  Unfortunately, it does not look like I will be able to add the Caribbean, as those maps use an unknown projection system (if anyone happens to know how to georeference the Caribbean maps, let me know and I’ll add them).

These charts were purchased from the National Aeronautical Charting Office (NACO) and are NOT CURRENT.  They are for simulation and entertainment purposes only!!

    Many times, you can get outdated air nav charts for free at your local airport. I have a huge pile of sectionals that I got from the map library at a local University. There’s no sense in buying the real, up-to-date charts if you’re not actually using them to fly!

  • Eric, you’re correct. The trick is getting them scanned. Easier to buy the digital maps from NACO than to track down a scanner big enough to scan them. The High Altitude Charts only set me back about $15.

    The Low Altitude Charts are a bit more expensive. If someone already has the digital Low Alt Charts and is willing to send them my way, that would work also.

    In your aviation mapping did you ever get the DoD enroute chart set from NIMA back when the DAFIF was publicly available? I guess now it is a bit dated (30 Aug 2007 last issue).

  • I did get some of those charts way back when. But I don’t have them anymore and I wasn’t able to georeference them because they didn’t provide the projection information. But if anyone still has them, I could take another look at them.

    I wanna low-alt IFR enroute.

    • I wanna low-alt IFR enroute.

      If I could get 10 or 11 people to donate $5 each, I’d buy them and put them online. Or maybe someone already has them and can get them to me. Otherwise, it’s hard for me to justify the cost on my own.

    What is the map projection for these High Alt E/R Charts? I’m guessing Lamberts Conformal Conic with 33° & 45° N standard parallels. If so what is the central meridian?

    • Spatial_Reference_Information:
      Map_Projection_Name: Lambert Conformal Conic
      Lambert_Conformal_Conic (Format:Deg-Min-Sec:
      Standard_Parallel: 45-00-00.0N
      Standard_Parallel: 33-00-00.0N
      Longitude_of_Central_Meridian: 095-00-00W
      Latitude_of_Projection_Origin: 39-00-00N
      False_Easting: 0.000000
      False_Northing: 0.000000
      Horizontal_Datum_Name: North American Datum of 1983
      Ellipsoid_Name: Geodetic Reference System 80

      But they all had to be converted to Geographic Projection for Google Earth :)

    Nice work on these! Were you using NACO’s PDF downloadable charts or is there something like their digital visual charts (geo-referenced TIFFs, I believe) available?

    Hey, topomatt very nice work. I was trying to use the Low Alt IFR enroutes for a moving map with weather overlay and was about to undertake the transformation of my weather data to this form. Do you know if the spatial reference information is the same for the Low Alt Ifr charts? Also I am a little new but was going to use “http://mathworld.wolfram.com/LambertConformalConicProjection.html” as a jumping off point does this seem reasonable to you? Any help would be appreciated! Thanks

    Any idea how to get the iPad to load this thing?

    When you mentionned that you “Extracted the images and manually georeferenced them”, how did you do that, using a paper map finding each lat/lon corner and orientation ?

    • topomatt

      The source maps were digital, but not georeferenced. Since I knew the projection/datum of the source images, it was a simple matter of entering the coordinates of several points from the maps into the GIS program I was using (GlobalMapper). GM was then able to transform the image into the Projection that Google Earth knows.

    Love those old sectionals.

    Ante todo cordiales saludos desde Venezuela.
    Me parece decepcionante la actitud que existe en relación a este tema nadie busca mas que acercarse un poco a la realidad, pregunto, que puede hacer alguien con una carta de vuelo real si los aviones en vuelo (que en su mayoría vuelan a mas de fl180, osea, 18.000 pies) pueden ser secuestrados para muestra lo del 11 de septiembre, ademas, si alguien quiere realizar nuevamente tal azaña lo que haría seria invertir unos dolares y comprar las cartas de vuelo, aja que hay de seguro en ello, lo que si me parece decepcionante e incluso ofensivo tratarnos a todos de la misma manera, no soy un terrorista; por otro lado son unos ladrones por querer vender un material que primero es publico y segundo no es de su propiedad osea, no tienen copyright, es decir ladrones.
    Por ultimo, y aludiendo a la persona que dice que fly simulatior tiene todas las rutas, amigo eso es falso, tendría que usted bajar los parches de actualización y todavía faltan, por otro lado y para culminar yo quiero volar con mis cartas y no con un gps por que a mi me aburre tal azaña (diría estupidez)por que prefiero vivir en los años 80 y volar de vor a vor o de nbd o lo que sea nadie me lo puede impedir.
    PD. SON UNOS LADRONES QUE DECEPCIÓN. (No soy un niño soy mayorcito ya 37 años y palante).
