There must be an entry in each field. The defaults will give a GIF of the local continent, projected from the server. Maps will take from 30sec-5mins on an unloaded server, depending on the amount of information plotted. Microsoft IE will time out after 3mins.

Title of Map

Decorative Title across top of Map (e.g. 2m Contest).

Location of center of azimuthal equidistant projection Help - don't know lat/lon (USA only)

(Some combinations of lat/lon will hang the server - I'd guess <1% of inputs. Running the same lat/lon on another machine with the same OS and the same version of ghostscript will give a valid map. I assume ghostscript has trouble with one of the plotted points from that lat/lon. If you do not get a simple map back in 1min, hit the "Stop" botton on your browser and re-run the form after moving your lat or lon by 0.001degree. )

Name of QTH - eg WA3ZZZ, or Mt. Monadnoc (will be small label at bottom left of map).
location accepted formats gridlocator (eg FM05lw) or latitude (-89.9<lat<89.9, in decimal degrees, N is +, S is -)
longitude (-180.0<lon =<180.0, in decimal degrees, E is +, W is -) (entry ignored if gridlocator used in previous field)

Note: the USA has positive latitude and negative longitude. This is the most common mistake made in drawing maps and leads to maps centered in central asia by hams with US call signs. The next most common mistake is exchanging lat/lon leading to maps centered near the north pole.

cross-hair marker at QTH

Location for Center of Page Help

Center is offset (i.e. center of page is not at QTH).
If you've chosen to offset the center of the map then you must enter the lat/lon for the new center.

The coords here put North America in the center of the page.
latitude/gridlocator of center of page
longitude of center of page (ignored if gridlocator used above)

Continents to include in map Help
africa ( 988,429 bytes )

Map Scale

The display thinks it is A4 or about 8.5x11" i.e. about 10cm from center to edge. The whole world require a map of radius 20,000km (thanks to Napoleon).

Geographical Features Help

grid squares to be filled with elevation data (blank separated list of 2char grids eg FM FN EM EN case insensitive, takes about 2mins/grid, elevation maps will be run at a lower priority than regular line maps)

Greyline by time/date (UTC not local time) help

None
Sunrise Greylines at your QTH throughout the year
Sunset Greylines at your QTH thoughout the year
sunrise line and sunset line at QTH, for date below (time ignored). Lines will be close at equinoxes, separated at solstice.

DXCC

[new]Dec 2011: fixed thanks to bug fixes from G8SQH. Original code had the label at the negative of the bearing.

DXCC Country Call Signs from Bill K2DI

label at Capital of country

Islands on the Air, the RSGB IOTA Help

Mountain Top Lists and Rovers

(currently NE USA only. Try scale = 50km/cm, QTH = FN42mm. Note distance bearing lines from QTH to selected mountains)
NE USA. A mixture of mountaintops, beacon sites and rover locations mostly in N.E. USA by N2MH. The most recent version of this file is at The N2MH RoveSite
NE USA. mountaintops by N1BWT and KH6CP/1
Put in a few demonstration rovers too.

USA Ham Density - for planning VHF rover and DX-peditions help and example maps

(22 Mar 00, looks like this had stopped working for a while, sorry about this)
low resolution (by 4char grid squares), example
high resolution (by 6char grid squares), example. This map takes several minutes to draw. Watch out if you have a link that times out, eg a proxy server or are using IE.
