WeatherGraphix
May 28, 1993
CHANGES IN VERSION 3.2 over previous versions.....
* OK, folks, you can now put your WEATHER.STN file back the way it was.
No longer do you have to expand WEATHER.STN to add all those watch box
locations that weren't getting plotted. Because now you have WEATHER.LOC,
a comprehensive listing of thousands of stations, thanks to WeatherGraphix
user Mark Hayes. If WeatherGraphix STILL can't locate a station, add
it to WEATHER.LOC. In this version and future versions, WEATHER.STN will
be used ONLY for surface and upper air station plotting -- not for other
uses.
* You can now use Map Station IDs to overlay VORs, airfields, and other
navaids for aviation use. This information is contained in WEATHER.LOC.
* Radar heights are being parsed in a different manner, so you should see
a lot more information on the chart.
* Radar cell movement can be overlaid on the map using a new command in
the Radar submenu.
* Watch boxes, convective outlooks, and sigmets are being parsed somewhat
differently to make plots more bug-free.
* A "too many open files" bug that caused eventual crashing of
WeatherGraphix has been fixed.
* The analysis filter option in Configuration has been restored to normal
operation.
* Mexican surface observations may be included in your surface data
capture.
* Upper-air data from WeatherBank (in the table format) can now be
imported as rawinsonde data. Remember to put this information in your
DATA.UPR or equivalent file.
* Upper-air support has been expanded to all levels, from 1000 to 100 mb.
* Canadian RAOB (rawinsonde) observations are now imported successfully.
* A problem with the New Dataset (specifying new times) has been fixed.
* I'm still working on the background color problem. Please keep in touch
with me on this issue.
* EGA graphic support has now been re-established. Append /E to WEATHER
when you start up the program to put it in EGA mode.
* You can now title your chart (in the Other options menu). This will
prefix a user-defined title to the legend whenever you generate a chart.
.........................................................................
Miscellaneous changes in WeatherGraphix 3.1 (over 3.0).....
* For fast basemap plotting it is HIGHLY recommended that you use a disk
cache program (such as SMARTDRIVE in MS-DOS 5.0, etc), with a storage
space for files of minimum 10K, maximum 30K or higher. On a 386DX,
basemap plotting should not take longer than 3 seconds, not much slower
than earlier versions of this program.
* Latitude/longitude lines used in V3.1/V3.2 are not available when
upgrading your older program copy; these are part of a change which
cannot be packaged with demo programs.
* Convective outlooks are now plotted (registered users only). This data
must be stored in your surface DATA.SFC or equivalent file. The only
problems that could arise are unlocated stations and/or an improperly
formatted report. These convective outlooks must be the raw,
original AC bulletin (available on Weathermation and Accu-Data, not
available on CompuServe). You may use either the ACUS1 (day 1) and/or
the ACUS2 (day 2) bulletin. If stations could not be located, modify
your WEATHER.LOC file to add the 3-letter identifiers and their
locations.
* It is known that there are some problems with the colors if you radically
modify the background colors, etc. Please be patient -- this will be
improved in an upcoming release.
MISCELLANEOUS changes over WeatherGraphix V3.0.....
* Flaky, slow altimeter-setting analysis has been corrected
* Corrected a bug that caused rare occasions of altimeter setting plots
of "000" which were really another value
* Station IDs and cities are plotted in small fonts for your enjoyment.
* Modified aspect ratio slightly to improve appearance of geography.
* The heat index analysis is now corrected. The equation was in error.
* In radar composites, a bug was present in earlier versions which
occasionally caused the radar station to be mislocated (though its
echoes were located fine). This has been corrected.
* Corrected bug for radar cell plotting... a lot of anomalous echoes should
be gone.
* Slightly revised WEATHER.STN master listing.
* Incorporates a few bug fixes, one which corrects a flaw where WeatherGraphix
inevitably crashed after a heavy-use session with lots of Station
Requests (it gave Error Code 4, i.e. too many open files)

UPGRADE INFORMATION
============================================================================
UPGRADING from WEATHER PRO V2.0 or later
----------------------------------------
1. Unzip this package to a temporary, empty directory. To set up the
empty directory, just enter, for instance, MD C:\WXTEMP.
2. Copy WEATHER.PLT from your old directory or your registered disk
to the temporary directory.
3. If you would like to keep your customized city listing, copy WEATHER.CTY
from the old directory to the temporary directory.
4. The old WEATHER.STN list is -NOT- compatible with Weather Pro V3.0.
5. Run WEATHER in the temporary directory to make sure everything runs
properly.
6. If all looks OK, delete everything in your old directory and copy all
contents of the temporary directory to the old directory. Then
delete the temporary directory.
REGISTERED RADARSCAN V1.0, V1.1 USERS ONLY
------------------------------------------
This is a rather extensive update, since the philosophy and structure
of the program has changed, along with the name.
To update your program, make a new directory, preferably C:\WEATHER,
and unzip this entire package into it. Then follow these instructions.
1. MANDATORY!!! Copy RADAR.PLT from your old directory, renaming it to
WEATHER.PLT in the new one. You can use a command like:
COPY C:\RADSCAN\RADAR.PLT C:\WEATHER\WEATHER.PLT
2. If you have customized your town and city list, copy RADAR.CTY from
the old directory to WEATHER.CTY in the new one. Allow it to
overwrite the old file.
3. Your new program is WEATHER.EXE in the new directory. Read the
enclosed WEATHER.DOC and type WEATHER by itself to run the program.
4. When you get a chance, delete RadarScan from your disk drive as you'll
no longer need it.
Changes RadarScan users might want to be aware of:
* Your data file is no longer RADAR.TXT, but DATA.TXT.
* There are no command line parameters anymore. However, if your data
is not in DATA.TXT, specify it by adding it to the end of the WEATHER
startup command (e.g. WEATHER 04JUL92.DAT).
* You do not need to memorize the time for the weather data. Weather
Pro will accurately figure it out for you.
* All commands are now keystroke-driven. Once inside the program, you
can plot or look at maps or change the configuration. See WEATHER.DOC
for further details.
