Old News:

13 Feb 2020: If you're running az_proj from the command line and have suddenly started getting

Error: /undefined in .devicename
here's the cure. Thanks to Rob, KA2PBT and Chris, N0UK for alerting me.

30 Jul 2019: AZ_PROJ is 25 years old. The code was released on 30 Jul 1994, by NV3Z and myself at the NEWS VHF conference in TN. It runs a lot faster now (thanks to Moore's Law).

Making a map here on the Server.

time animation This server can generate a downloadable customised colored map using a subset of AZ_PROJ's features. Anything you can do here, you can do at home too (the server is running the same code). You can use the short form if you only want to change the scale and the location of the center of the map. Otherwise, you can fill out the long form to use all of the server's features (elevation, center offset, gridsquares, lat/lon lines, geographical features, greyline, compass, beacons/TV stations).

Color Problems If the nighttime part of the globe animations are gray, rather than lightblue, (or you have blank spaces in this sentence) then here's an explanation.

Other Online Map Resources

Roger Hedin SM3GSJ has a Microsoft windows based azimuthal equidistant mapping program for hams which uses the same wdb database for the geographical information as this server.

The GARP Server is another az-equidistant map server. It has altitude (and ocean depth) information.

About the Azimuthal Equidistant Map Server

vi home page The server code is written in Perl. AZ_PROJ is written in Postscript. The animations of the globe(s) (viewable on netscape ver>= 2.02) were produced with gifmerge (Jul 2002, the link is dead).
