; PROCEDURE plot_map_asi_nipr
;
; :PURPOSE:
;    Draw NIPR all-sky imager data on the world map
;
; :Params:
;    asi_vns:   tplot variable to be plotted
;
; :Keywords:
;    set_time: time to plot all-sky imager data
;              (ex., '2012-01-12/21:30:00' or Unix time)
;    coord: the name of the coordinate system.
;           'geo' or 0 for geographic coordinate
;           'aacgm' or 1 for AACGM coordinate
;    glatc: geographical latitude at which a plot region is centered
;    glonc: geographical longitude at which a plot region is centered
;    scale: same as the keyword "scale" of map_set
;    altitude: altitude on which the image data will be mapped.
;              The default value is 110 (km). Available values are 90, 110, 150, 250.
;    colorrange: range of values of colorscale (this can be an array)
;    erase: set to erase pre-existing graphics on the plot window.
;    position:  position of the plot frame in the plot window
;    label: set to label the latitudes and longitudes.
;    stereo: use the stereographic mapping, instead of satellite mapping (default)
;    coast: set to draw coast
;    mapcharsize: size of the characters used for the labels.
;    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
;    notimelabel: set to surpress drawing the time label
;    timelabelpos: position of the color scale in the noraml coordinates
;    tlcharsize: size of the characters used for the time label
;    nocolorscale: set to surpress drawing the color scale
;    colorscalepos: position of the color scale in the noraml coordinates.
;                   Default: [0.85, 0.1, 0.87, 0.45]
;    cscharsize: size of the characters used for the colorscale
;
; :EXAMPLES:
;   plot_map_asi_nipr, 'nipr_asi_hus_0000'
;   plot_map_asi_nipr, 'nipr_asi_hus_0000', glatc=65., glonc=-15.
