Using OpenADDE servers with HYDRA
to read GOES and MSG data

In order to use local (McIDAS) AREA files for GOES and MSG with HYDRA, it is necessary to install the OpenADDE servers on your machine and configure them appropriately.  This page contains some notes about this.

Install OpenADDE Servers

Special note for Windows XP.

Note:  if you are installing on Windows, you must first obtain Windows Services for Unix (SFU) from <>.  Note that you must install this package as an Administrator, and during the install, you must elect to install the GNU gcc compilers and associated files.  Please note: 

Comments for all operating systems.

Please go to the page at: <> to obtain the OpenADDE servers.  Follow the instructions on this page to do the install.  Please note:  the install files should be put into the $HOME directory of the user you choose and the installation run from there.  This will create a an "openadde" directory for all the installed files; you may remove the installer files and scripts afterwards.

Configure the ADDE servers

After you install the OpenADDE servers, you must also configure the ADDE server's catalog file,  RESOLV.SRV for use with HYDRA.  This file will be found in the $HOME/openadde/data directory for the user underwhich you installed.   Configure the RESOLV.SRV file to read like this:

# Example McIDAS RESOLV.SRV file
# Fields:
# N1= Group name
# N2= Descriptor name
# TYPE= Data type (Only IMAGE supported by free servers)
# RT= Realtime (Y/N)
# K= File format
# R1= Begin file number
# R2= End file number
# MASK= Filename mask for data files
# C= Comment
# Examples:
These three entries specify that:
Note that all these AREA files should be full disk, maximum resolution!

Finally, the actual AREA files must reside in this directory or you can alter the MCPATH variable (in the $HOME/.mcenv file) to search more directories.
