31 Oct 2018: We're back. I've installed my own version of gs in my home directory. That should be upgrade proof.

30 Oct 2018: It seems Mark has reinstalled the non-working gs again without telling me. I'll do what I can. Sorry for the interruption of service.

21 Sep 2018: Mark WM7D, the person providing the server, had installed the latest version of gs (9.18). It didn't work (Joe's rule; never upgrade a working machine). After I let him know the maps didn't work any more, Mark compiled his own version of 9.18 and it worked.

20 Sep 2018: The machine stopped producing maps about a day ago. The error when az_proj is run under gs is Error: /undefined in .devicename

27 Sep 2018: An astute user out in az_proj land, running az_proj from the command line, has run into the same problem. It seems that the developers have broken gs again and it's now a feature. They've deprecated .devicename. A couple of decades ago, devicename was changed to .devicename, for no reason that I understood, requiring gs version dependant work arounds in the az_proj postscript code. I would have hoped that they wouldn't do something like this again.

Looking in ghostscript 9.21 devices you find that raster devices, like inkjet printers (and presumably png output, which az_proj uses) were deprecated in about 2017. You need to use an ijs device. For the moment if you compile gs_9.18 yourself with the .dev files for the devices, then gs works as before, but if you install the Ubuntu 9.18 binary, which presumably uses the ijs devices, you get the above error. Someday when I have nothing better to do, I'll figure out the new way of doing it. In the meantime I'll just run on the older versions of gs.

NEW: Would you like to be a AZ_PROJ map server site ?

Joe last wasted time on this page on 08-Feb-2015, last server code upgrade 29-Oct-2017, running AZ_PROJ v1.1.7 21-Dec-2011 Changelog.

Fast Option: If you've been here before and know what to do, you can just go make a map using the short form or the long form

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).
