Basic Examples  (2)

Sharpen a circular region near the Taj Mahal and blur the region outside it:

Wolfram Language code: GeoGraphics[{GeoStyling["StreetMap", EdgeForm[Red], GeoStylingImageFunction -> Sharpen], GeoDisk[Entity["Building", "TajMahal"], Quantity[0.5, "Miles"]]}, GeoBackground -> GeoStyling["StreetMap", GeoStylingImageFunction -> (Blur[#1, 25]&)], GeoRangePadding -> Quantity[0.2, "Miles"]]

Show the geo background of a geo histogram in gray levels:

Wolfram Language code: GeoHistogram[GeoPosition[«1»], GeoBackground -> GeoStyling["StreetMap", GeoStylingImageFunction -> (ColorConvert[#, GrayLevel]&)]]

Applications  (2)

Use the flag of a country as an image effect:

Wolfram Language code: CountryData["DemocraticRepublicCongo", "Flag"]

Place copies of the flag on the country and blur surrounding countries:

Wolfram Language code: With[{c = Entity["Country", "DemocraticRepublicCongo"]}, GeoGraphics[{{GeoStyling["StreetMap", GeoStylingImageFunction -> (Blur[#, 4]&)], Polygon[#]}& /@ CountryData[c, "BorderingCountries"], GeoStyling["StreetMap", GeoZoomLevel -> 5, GeoStylingImageFunction -> (Sharpen@ImageCompose[#, ImageAssemble[Table[SetAlphaChannel[Image[CountryData[c, "Flag"]], 0.2], {5}, {4}]]]&)], Polygon[c]}]]

Apply various image processing effects to neighboring countries:

Wolfram Language code: GeoGraphics[{ GeoStyling["ReliefMap", GeoStylingImageFunction -> ColorNegate], Polygon[Entity["Country", "Austria"]], Polygon[Entity["Country", "Switzerland"]], GeoStyling["StreetMap", GeoStylingImageFunction -> (ImageEffect[#1, "Charcoal"]&)], Polygon[Entity["Country", "France"]], GeoStyling["ReliefMap", GeoStylingImageFunction -> ({0, 0} /. StationaryWaveletTransform[ColorCombine[Take[ColorSeparate[#1], 3][[{2, 3, 1}]], "RGB"], Automatic, 2][{0, 0}, "Image"]&)], Polygon[Entity["Country", "Germany"]] }]
