+Internet Retrieval of Satellite Data
+====================================
+
+### Data Retrieval Toolkit
+Data retrieval uses the freely-available "OpenDCS Toolkit". OpenDCS is a
+limited version of the licensed Sutron "DCS Toolkit". Information on
+obtaining and using the tookit can be found here:
+https://dcs1.noaa.gov/LRGS/LRGS-Client-Getting-Started.pdf
+
+The non-open source documentation can be very useful, it can be found here:
+http://lighthouse.tamucc.edu/dnrpub/Sutron/XPert/Software/ilex%20Software/DCS%20Tool%20Users%20Guide_4-4.pdf
+
+### Accounts
+You will need to set up an acount with NOAA (https://dcs1.noaa.gov/) to
+retrieve Satellite data over the internet.
+
+### getDcpMessages
+getDcpMessage is a command line utility that fetches the asked for imfv283 data
+from the server. You can also use the GUI to fetch it.
+
+### The Search Criteria File
+The file "Criteria.sc" contains the information used by getDcpMessages to
+request data from the data server. It can be set up with a test editor,
+or by using the opendcs GUI.
+Example contents:
+
+DAPS_SINCE: 2014/001 17:48
+DAPS_UNTIL: now
+NETWORKLIST: C:\networklists\DCPlist.NL
+DAPS_STATUS: N
+RETRANSMITTED: N
+ASCENDING_TIME: true
+RT_SETTLE_DELAY: true
+
+### NETWORKLIST File
+The networklist file, list the stations, and their related GOES code, that you
+want to download for a given call to getdcpmessages.
+The NETWORKLIST is the file ON THE GOES SERVER, not the local system.
+Whatever name you used to upload it, including directory, will be the name on
+the server. And it must be loaded to all servers you plan to use.
+You can load it using either the opendcs gui, or by using the -N option for getDcpMessages.
+
+### USGS ftp site.
+The USGS stores a copy of the "OpenDCS Toolkit" and it's documentation at
+the following ftp site. Use is strictly limited to the terms and prohibitions
+as detailed at https://dcs1.noaa.gov
