GeoStyling[mapstyle]

displays faces of polygons and other filled geo objects using mapstyle.

✖

GeoStyling[mapstyle,directive]

uses mapstyle with the given graphics directive applied.

Details and Options

GeoStyling is a directive for GeoGraphics that applies textures and styling directives that are useful for maps.
GeoStyling applies to Polygon, GeoDisk, FilledCurve, Triangle, DayHemisphere, NightHemisphere, and GeoVisibleRegion.
Possible forms for mapstyle include:

	Automatic	use default styling
	None	use no explicit styling
	"ContourMap"	elevation data as contours
	"Coastlines"	geo background style displaying coastlines
	"CountryBorders"	geo background style displaying country borders
	Dated["CountryBorders",year]	geo background style displaying historical country borders
	"OutlineMap"	schematic region
	"ReliefMap"	elevation data as color with shadows
	"Satellite"	satellite imagery
	"SatelliteWithLabels"	satellite imagery with labels
	"StreetMap"	street map data
	"StreetMapLabelsOnly"	street map labels only
	"StreetMapNoLabels"	street map data omitting labels
	{"GeoImage",image}	apply image as a texture to unprojected polygons and project
	{"Image",image}	apply image as a texture to the projected polygons

GeoStyling[Automatic] is automatically applied by default to geo graphics and uses partial opacity with no explicitly specified color. It therefore inherits the default Graphics color behavior, meaning filled geo primitives are black in color but appear as transparent light gray when combined with their default partial transparency.
GeoStyling[None] removes any geo styling that has been set by previous GeoStyling specifications (including any set by GeoStyling[Automatic]). Using no geo styling results in the same default styles for geo graphics as for the usual Graphics (black with no transparency).
GeoStyling[] is equivalent to GeoStyling[None].
GeoStyling[directive] is equivalent to GeoStyling["OutlineMap",directive].
GeoStyling[mapstyle,directive] appends a graphics directive (or collection of individual directives inside an enclosing Directive) to the set of directives used to style a given mapstyle. All directives take effect for "OutlineMap", but only Opacity and EdgeForm take effect for other map styles.
The most recently applied GeoStyling specification in a geo graphics expression takes precedence. For geo primitives, GeoStyling specifications (including those from Automatic styling) take precedence over explicit graphics style directives added after the currently active GeoStyling. As a result of the default styling of GeoStyling[Automatic], bare color directives take effect by default, while GeoStyling must be explicitly wrapped around Opacity in order to change the transparency of filled geo primitives.
GeoStyling accepts most options applicable to Graphics. In addition, the following geo-specific options can be given:
GeoStylingImageFunction None image processing function to apply

GeoZoomLevel Automatic level of detail for styled geo graphics
GeoStyling["ContourMap",opts] accepts the same options as ListContourPlot.
GeoStyling["ReliefMap",opts] accepts the same options as ReliefPlot.
