## MAP2D_COORD

[Next Routine] [List of Routines]

     PROCEDURE map2d_coord

     :DESCRIPTION:
        Set the coordinate to the geographic or AACGM.

     :PARAMS:
        coord: the name of the coordinate system.
            'geo' or 0 for Geographic coordinate
            'aacgm' or non-zero numbers for AACGM coordinate

## MAP2D_GRID

[Previous Routine] [Next Routine] [List of Routines]

     PROCEDURE map2d_grid

     :DESCRIPTION:
        Draw the latitude-longitude mesh with given intervals in Lat and Lon.

     :KEYWORDS:
        dlat:  interval in Latitude [deg]. If not set, 10 deg is used as default.
        dlon:   interval in Longitude [deg]. If not set, 15 deg (1 hour in local time) is used as default.
        color: number of color table to be used for drawing lat-LT mesh
        linethick: thickness of lines/curves used for the mesh

     :EXAMPLES:
        map2d_set, /nogrid         ;map2d_set automatically calls map2d_grid unless nogrid keyword is set.
        map2d_grid, dlat=10., dlon=15.

## MAP2D_INIT

[Previous Routine] [Next Routine] [List of Routines]

     PROCEDURE map2d_init

     :DESCRIPTION:
        Initialize or modify the environment for drawing 2D data

     :KEYWORDS:
        reset: set to reset map2d system variables
        set_time: the time for which 2D data is drawn on the world map.
        coord: the name of the coordinate system.
               'geo' or 0 for geographic coordinate
               'aacgm' or 1 for AACGM coordinate
        glatc, glonc: geographic latitude and longitude of the center
                      of the map.
        scale: same as the keyword 'scale' of map_set procedure.

## MAP2D_SET

[Previous Routine] [Next Routine] [List of Routines]

     PROCEDURE map2d_set

     :DESCRIPTION:
        A wrapper routine for the IDL original "map_set" enabling some
        annotations regarding the visualization of 2D data.

     :KEYWORDS:
        glatc: geographical latitude at which a plot region is centered.
        glonc: geographical longitude at which a plot region is centered.
               (both glatc and glonc should be given, otherwise ignored)
        scale: same as the keyword "scale" of map_set
        erase: aet to erase pre-existing graphics on the plot window.
        position: gives the position of a plot panel on the plot window as the normal coordinates.
        label: set to label the latitudes and longitudes.
        stereo: use the stereographic mapping, instead of satellite mapping (default)
        charsize: size of the characters used for the labels.
        coord: name of the coordinate system.
            'geo' or 0 for Geographic coordinate
            'aacgm' or non-zero numbers for AACGM coordinate
        set_time: this is used to calculate MLT when coord is 'aacgm'
        mltlabel: set to draw the MLT labels every 2 hour.
        lonlab: a latitude from which (toward the poles) the MLT labels are drawn.
        nogrid: set to suppress drawing the lat-lon mesh

     :EXAMPLES:
        map2d_set
        map2d_set, glatc=70., glonc=180., /mltlabel, lonlab=74.

## MAP2D_TIME

[Previous Routine] [List of Routines]

     PROCEDURE map2d_time

     :Description:
        Describe the procedure/function.

     :Params:
        time:  Set the time for which 2D data is drawn on the world map

     :Keywords:
        quiet:   If not set, then the plot time is shown in the command-line console

     :EXAMPLES:
        map2d_time, '2007-03-24/14:24'
        map2d_time, 1424
