__init__ writes a madPcolorWedgeKmlScan to a file.

Inputs:

isprintText - a string giving isprint output without headers. The 9 parameters are (gdlatr, gdlonr, galtr, range, az1, az2, el1, el2, <parameter value>). Any missing data should be written as "missing" or other string that cannot be converted to a float. gdlatr, gdlonr, galtr are the station location

scanType - must be az or el_lat (for north or south el scans), el_lon (for east or west el scans) or el_gcdist (for all other el scans. For az - x is long, y is lat for el_* y is always alt, and x is either lat, lon, or great circle distance

fullFilename - full path of file containing kml file to be saved. Extension must be kml, or exception thrown.

minColormap - minimum parameter value (defaults to lowest parameter value)

maxColormap - maximum parameter value (defaults to highest parameter value). However, if both minColormap and maxColormap == None, autoscaling applied.

instName, instDesc, instLat, instLon, instAlt - used to create a placemark for the radar. If instLat or instLon missing, no placemark added.

colorMap - A matplotlib colormap to use to create colors. If None, then blue minimum and red maximum

Returns: void

Affects: Writes fullFilename to disk

_createKmlText creates kml text

Inputs:

dataGen - list in form (dataValue, (point1_lat, point1_lon, point1_alt), (point2_lat, point2_lon, point2_alt), (point3_lat, point3_lon, point3_alt), (point4_lat, point4_lon, point4_alt)) maxColormap minColormap lookLat lookLon lookAlt scanType instName, instDesc, instLat, instLon, instAlt - - used to create a placemark for the radar. If instLat or instLon missing, no placemark added. colorMap - A matplotlib colormap to use to create colors. If None, then blue minimum and red maximum

_generateWedges (
        self,
        isprintLines,
        scanType,
        )

_generateWedges is a python generator that return a data wedge in the form (dataValue, (point1_lat, point1_lon, point1_alt), (point2_lat, point2_lon, point2_alt), (point3_lat, point3_lon, point3_alt), (point4_lat, point4_lon, point4_alt))

Inputs:

isprintLines - a list of line with 9 parameters that are (gdlatr, gdlonr, galtr, range, az1, az2, el1, el2, <parameter value>). Any missing data should be written as "missing" or other string that cannot be converted to a float. gdlatr, gdlonr, galtr are the station location. No wedge is returned for a missing data line

scanType - must be az or el_lat (for north or south el scans), el_lon (for east or west el scans) or el_gcdist (for all other el scans. For az - x is long, y is lat for el_* y is always alt, and x is either lat, lon, or great circle distance

_getKmlRGB (
        self,
        value,
        transparent=False,
        wrap=False,
        )

_getKmlRGB returns a Kml color string given a value between 0 qnd 1.

If transparent == False, solid color. Otherwise transpanency set to 50%

If wrap, colors at zero and 1 wrap. Otherwise, extremes red and blue

If invert, use value = 1 - value

_getLimits ( self,  isprintLines )

returns (newLonMax, newLonMin, newLatMax, newLatMin, newAltMax, newGreatCDist, newParmMax, newParmMin) given isprint lines with parameters (gdlatr, gdlonr, galtr, range, az1, az2, el1, el2, <parameter value>)

We only look at the end points of ranges and the station location

        galtr,

        az2,
        el1,
        el2,
        value,
        )

_getWedge returns return a data wedge in the form (dataValue, (point1_lat, point1_lon, point1_alt), (point2_lat, point2_lon, point2_alt), (point3_lat, point3_lon, point3_alt), (point4_lat, point4_lon, point4_alt)).

Inputs: gdlatr, gdlonr, galtr - location of radar range, diffRange1, diffRange2 - range of center of wedge, and distance in and out from there az1, az2, el1, el2 - start and end aximuth and elevation. Which is used depends on scanType value - float data value

        gdlatr,
        glonr,
        gdlat,
        glon,
        )

getGreatCircleDist return the great circle distance in. Taken from madDeriveMethods c code.

Inputs: gdlatr, glonr: reference point on earth's surface gdlat, glon: second point on earth's surface
