I am trying to plot wind vector data for Hawaii. When I use this command, I get errors stating that there is missing data for some number of GeoPositions:
wind=WindVectorData[Hawaiian islands, October 1, 2019, “DownwindGeoVector”]
If I substitute “Hawaiian islands” with “Hawaii” I get a bunch of GeoVector errors, followed by a list of TimeSeries.
What do I need to do to create a GeoVectorPlot for the area around Hawaii, including the 8 main islands?
Hi Brian,
GeoVectorPlot expects a list of positions and the corresponding vectors. e.g.
hawaiiPolygon = Entity["AdministrativeDivision", {"Hawaii", "UnitedStates"}]["Polygon"];
(* Extracts points *)
hawaiiPoints = Flatten[hawaiiPolygon[[1, 1]], 1];
(* Get the wind data for noon on Oct. 1, 2019 *)
wind = WindVectorData[hawaiiPoints, DateObject[{2019, 10, 1, 12, 0, 0}], "DownwindGeoVector"];
GeoVectorPlot[wind]
Different background and vector coloring
GeoVectorPlot[wind, GeoBackground -> "ReliefMap", VectorColorFunction -> Hue]
Thank you very much!
