- Announcement: AZ_PROJ v1.04 Azimuthal Equidistant Postscript Mapping package
- available from the AZ_PROJ Map Server Website at
-
- http://www.xray.duke.edu:1080/
-
- or by ftp
-
- ftp://ftp.xray.duke.edu/pub/az_proj
-
- The file is azprj104.zip (approx 1.2M).
-
- The new features are
-
- 1. Orthographic orientation option
- (The Orthographic projection puts South at the top of the
- page). Needed for people in the Southern Hemisphere (-:
-
- 2. ARRL grid square labelling style added. The ARRL
- style has much smaller labels for the grid squares and puts
- the letter square labels in the bottom left of the square.
- The grid square labelling style used in v1.00-v1.03 is
- now called az_proj style.
-
- 3. Several different options added for shading
- worked grid squares (different colors, different cross
- hatching methods) so that it's possible to mark grid
- squares worked by two (or more) different people. See
- the sample grid.dat file for more info. You can also use
- the same options for marking the grids at the ends of a
- qso (see qso.dat for examples).
-
- 4. Plotting TV stations for North America (NA)
- and Europe. A full list of NA stations broadcast
- stations (MW, FM, TV) in machine readable format has been
- produced by Colin K4SSO. A separate file consisting of
- only the NA Channel 2 stations (55.25MHz useful as 6m
- propagation markers) has been added. A list of European
- TV stations (from Geoff Brown and Emil W3EP) has been
- converted to machine readable format, for 6m propagation
- markers.
-
- 5. DAT file formats are still changing (sorry).
- Anything which is a transmitter (TV station, rover, beacon,
- repeater) all have the same format. The only thing which
- changes is the symbol displayed. Please note the changes
- detailed in each .DAT file (at most you will have to add
- an extra colon or two to your old files if you want to update
- them).
-
- 6. GRID2.DAT file format of v1.03 is now standard
- (and called the GRID format, with no 2). The old format from
- v1.00 which had been used in parallel, has been
- dropped.
-
- 7. An install.bat file has been added to install
- AZ_PROJ and Ghoscript onto a DOS machine with a VGA or
- SVGA monitor. Sample batch files for testing both Ghostscript
- and AZ_PROJ are included.
-
-
- 8. Easier method for choosing when to draw grid square
- borders and compass (in az_ini.ps). (Also clearer explanation
- of what's happening, I hope).
-
- 9. Display of USA by call areas (0..9) rather than
- (or as well as) by states.
-
- 10. Labelling feature. The center of the line on which
- the label sits, is at the lat/lon (cf annotations where a blob
- is at the lat/lon). This feature can be used for labelling
- continents, countries... The size of the characters can be
- chosen differently for each entry, and the size chosen scales
- with the map scale. You can try this feature out, by labelling
- the US call areas with the file us_call.dat when the numbers
- 0..9 will be drawn in each call area. The borders of the call
- areas can be drawn by turning on /draw_USA_call_areas in
- az_ini.ps.

-
- General blurb about AZ_PROJ
-
- AZ_PROJ is a collection of postscript files and data
- files for generating azimuthal equidistance projections of the earth
- from (almost) any point on earth. It can plot color maps of the
- surface of the earth on any scale, draw and/or label grid squares,
- show worked grid squares on a band(s) of your choice, dxcc
- countries (and countries worked an a particular mode, eg CW/SSB),
- mountain tops, rovers, repeaters, beacons and can use NMEA input
- from a GPS receiver to center the map.
-
- AZ_PROJ can be run on ANY computer (Mac, PC/DOS/Win/DVX, Unix)
- and output to a postscript device (printer, ghostscript runing on a
- unix or DOS machine with a ghostscript compatible printer, eg
- HPcolor inkjets). Ghostscript will also allow display of the maps
- on screens.
-
- Although a rudimentary understanding of postscript will
- help in running AZ_PROJ, sample .bat files are supplied to make
- initial maps and it should be possible to make simple changes to
- the az_ini.ps and *.bat files to get the maps you want.
-
- To display the maps on a screen or to use a
- non-postscript printer, you should first obtain ghostscript
- (available for PC (DOS, Win, DesqViewX) or Unix) from your
- favorite ftp site (try ftp.cs.wisc.edu/pub/ghost)
-
- The AZ_PROJ files are GNU copylefted.
