NCAR Graphics provides a number of different projections. Below is a table of the legal strings for this parameter and their associated projections. This is a confusing parameter that you should probably leave at zero unless you really need to change the coarseness of the map. If this parameter is set to the special value of 0, SatView will automatically pick a reasonable value. MapState MapState determines the visibility of the map upon creating a satellite image window.
Legal values are On and Off.
Do not change these attributes. SatView will cease to function. MaskLand Set this option to True to fill in land masses visible in opaque images to the background color. Tell it how many vectors of a reasonable size you think ought to fit across the screen. Tinker with it until the plot is satisfactory.
