GeoStreamPlot
GeoStreamPlot[vecs]
generates a stream plot from the field of geo vectors vecs.
GeoStreamPlot[{vecs1,vecs2,…}]
generates a separate set of streams for each vecsi.
Details and Options


- GeoStreamPlot plots streamlines that show the local direction of the vector field at every point.
- Sets of vectors vecs can be given in the following forms:
-
GeoVector[…],GeoVectorENU[…],… combined geo vectors {vec1,vec2,…} list of individual geo vectors <loc1vec1,loc2vec2,… > association of locations and vectors - The geographic locations loci can be given in the following forms:
-
GeoPosition[{lat,lon}] latitude and longitude Entity[…] geographic entity Dated[ent,date] dated entity - The vectors veci can be given in the following forms:
-
GeoVector[{m,α}] vector with magnitude m and bearing α at posi GeoVectorENU[{ve,vn}] vector with east and north components - Data not given in these forms is ignored in forming the stream plot.
- GeoStreamPlot has the same options as GeoGraphics, with the following additions and changes:
-
Method Automatic methods to use for the plot PerformanceGoal $PerformanceGoal aspects of performance to try to optimize PlotLegends None legends for vector fields PlotTheme $PlotTheme overall theme for the plot RegionFunction True determine what region to include StreamColorFunction Automatic how to color streamlines StreamColorFunctionScaling True whether to scale the argument to StreamColorFunction StreamMarkers Automatic shape to use for streams StreamPoints Automatic determine number, placement, and closeness of streamlines StreamScale Automatic determine sizes and segmenting of individual streamlines StreamStyle Automatic how to draw streamlines - The arguments supplied to RegionFunction are lat, lon, vlat, vlon, Norm[vec].
- The value of region in RegionFunction->region can be an entity or geo polygon over which to plot.
- VectorPoints and StreamPoints accept collections of geo positions and entities.
