Class: radarToGeodeticService radarToGeodeticService.py

radarToGeodeticService is web service that allows access to the madrigal._Madrec.radarToGeodetic method.

Like all my python cgi scripts, radarToGeodeticService has the following structure: the entire cgi is contained in one class, with a main function at the end which serves simply to call the __init__ function of the class. This __init__ function is responsible for calling all other class methods. It is made up of a single try block, with the purpose of reporting all exceptions in well-formatted text to both the user and the administrator. The __init__ function first makes sure the pythonlib can be found. It then calls setScriptState to validate the the cgi arguments, which are simply the arguments for the isprint command.

If any uncaught exception is thrown, its caught by the __init__ try block. If its an MadrigalError, additional information is available. The catch blocks attempt to display the error message on the screen by backing out of of large number of possible tags, which might prevent its display (in any case, the error message will always be available in the page source. The formatted error message is also sent to the email address given in the siteTab.txt metadata file.

This script is not meant to be used directly by a user, and thus is named Service. It is meant to be used by scripting languages such as Matlab that want to call getInstruments via the web

Input cgi arguments:

        slatgd  - radar geodetic latitude

        slon - radar longitude

        saltgd - radar geodetic altitude

        az - a comma-separated list of radar azimuth in degrees (0 = north)

        el - a comma-separated list of radar elevation in degrees 

        range - a comma-separated list of radar range in km

Returns comma-delimited data, one line for point in lists:

  1. geodetic latitude of point

  2. longitude of point

  3. geodetic altitude of point

If error, returns error description
