QMAP

Name


      QMAP

Purpose


      Draw a quick map.

Category


Calling Sequence


      qmap, lat, lon

Inputs


      lat, lon = Latitude, Longitude of map center. in

Keyword Parameters


Keywords


        SCALE=sc Map scale (def=4E7).
        /GRID Add a coordinate grid.
        TITLE=ttl Optional map title.
        SUBTITLE=sttl Optional map subtitle title.
        PNG=png Name of PNG image to save map in.
        /HIRES Use high resolution coastlines.
        BGCOLOR=bgclr 24 bit Background color (def=white).
        CRAD=rad Radius of an optional circle to plot.
          Radius is in m by default but if rad is a string the
          units may follow and be nmiles, miles, km, meters,
          m, yards, feet. May be an array of radii.
        CCOLOR=cclr Optional array of 24-bit colors for circle,
          one for each radii (def=red).
        ALON=alon, ALAT=alat Optional area definition.
          If alon and alat have 1 element:
            Center of a circle of radius crad (def is
              lon, lat if CRAD is given).
          If alon and alat have 2 elements:
            Box defined by alon=[min_lon,max_lon],
              alat=[min_lat, max_lat].
          If alon and alat have 3 or more elements:
            Polygon defined by alon=[lon1,lon2,...,lonn],
              alat=[lat1,lat2,...,latn].
            Last point assumed to connect to first point.
        IMAGE=img Image to display on map. Assumed global.
        /CBAR Display color bar using last absolute color table.
          Call act_apply before calling qmap to set up the color
          table. Displays default bar range. May also set range:
        CBAR=[vmin,vmax] Display bar with the range vmin to vmax.
        CBTITLE=cbttl Title for color bar.
        /EXISTS Use existing window, else make a window.
        WINDOW=[nx,ny] Give size for a new window.

Notes


      Notes: Map is plotted using othographic projection and
        default colors.
