20 Jan 2022: There's a lot of maps being drawn with no continents or map features enabled. This is relatively new. The only way I know of doing this is to draw the default map with North America (the default) turned off. I can't imagine anyone needs this.
I initially assumed this had to be a bug in my code. However after a spate of these being drawn this morning, I looked at the az_ini.ps files producing these maps to find they came from the IPs of google, msn/bing and yandex bots. I assume webcrawlers now are zeroing out all options and sending a scripted "SUBMIT" to webpages they visit. This doesn't seem fixable with robots.txt.
At least I can stop worrying about it being a bug in my code or wondering why hams are drawing null maps.Old News:
13 Feb 2020: If you're running az_proj from the command line and have suddenly started getting
Error: /undefined in .devicenamehere'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).
NEW: Would you like to be a AZ_PROJ map server site ?

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
|What is AZ_PROJ?|
Most Wanted Grid Project, example maps US Ham Population Maps to help Rovers and VHF DX-pedition people plan their contests/vacations. (The Spring Sprints results and the Jul 2000 aurora opening maps show where the active VHF hams really are.)

|history of az_proj|
The QTH information from the 25,000 maps drawn from Oct 98 to Feb 00 was used to construct the aggregate map for the whole world and a close up of NA and Europe. Notable hot spots are the Galapagos Islands and Aruba (popular sites for DX-peditions). The eastern half of USA draws a disproportionate number of maps relative to the US ham population. The large number of maps centered on Kyrgyzstan, relative to the ham population, are probably by people in the US who don't know whether they are east or west of Greenwich. A spot in the ocean SW of Baja California is probably Pratas Is, BV9 by the same people.
|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).|
