GeoContourPlot
GeoContourPlot[{loc1val1,loc2val2,…}]
makes a geo contour plot from values vali defined at specified locations loci.
GeoContourPlot[locsvals]
uses a collection of locations locs with corresponding values vals.
Details and Options




- GeoContourPlot is also known as an isopleth map and thematic map.
- GeoContourPlot displays contour lines on a map where the fields of values interpolated from the geo locations are all the same.
- 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 - Multiple locations locs can be given in the following forms:
-
{reg1,reg2,…} list of individual locations GeoPosition[{pos1,pos2,…}] array of geo positions EntityClass[…] class of geo entities - The values vali can be given in the following forms:
-
vali positive number Quantity[vali,unit] magnitude with units - Multiple values vals can be given in the following forms:
-
{val1,val2,…} list of individual values QuantityArray[{val1,val2,…},unit] array of quantities - In GeoContourPlot[data], data can be given in the following forms:
-
<loc1val1,loc2val2,… > association of keys and values GeoPosition[{{lat1,lon1,elev1},…}] geo positions with elevations as the values WeightedData[…] positions with weights for values - GeoContourPlot has the same options as GeoGraphics, with the following additions and changes:
-
BoundaryStyle None how to draw RegionFunction boundaries BoxRatios Automatic effective 3D bounding box ratios ClippingStyle None how to draw values clipped by PlotRange ColorFunction Automatic how to color the plot ColorFunctionScaling True whether to scale the argument to ColorFunction ContourLabels Automatic how to label contour levels Contours Automatic how many or what contours to use ContourShading None how to shade regions between contours ContourStyle Automatic the style for contour lines InterpolationOrder None the polynomial degree in each variable of the interpolated density between data points LightingAngle None effective angle of the simulated light source MaxPlotPoints Automatic the maximum number of points to include Mesh None how many mesh lines in each direction to draw MeshFunctions {#1&,#2&} how to determine the placement of mesh lines MeshStyle Automatic the style for mesh lines Method Automatic the method to use for interpolation and data reduction PerformanceGoal $PerformanceGoal aspects of performance to try to optimize PlotLegends None legends for color gradients PlotTheme $PlotTheme overall theme for the plot RegionFunction (True&) how to determine whether a point should be included ScalingFunctions None how to scale individual coordinates - ColorFunction is supplied with a single argument, given by default by the scaled value of vali.

Scope (18)
Data (7)
Plot data associated with geo locations:
Plot gridded values over a specified range of coordinates:
Use an Association with locations for keys and values for counts:
Use WeightedData:
GeoRange is selected automatically based on the data locations:
Use GeoRange to focus on geographic areas of interest:
Specify the number of contours to use:
Use RegionFunction to restrict the density to a region:
Options (53)
BoundaryStyle (2)
ColorFunctionScaling (1)
Contours (7)
ContourShading (3)
The automatic shading is None to only show the contour lines:
ContourStyle (4)
The default contour style for data with elevations and a relief map GeoBackground is a black line for values above the sea level and a white line for values below:
The default contour style for data with elevations and a satellite map GeoBackground is a gray line:
Use None to not show contour lines:
GeoBackground (2)
GeoProjection (1)
Use GeoProjection to change the map projection:
GeoRange (1)
GeoRangePadding (1)
Use GeoRangePadding->None to remove padding:
Use 250 kilometers of padding on each side of the map:
Specify padding for latitude only:
GeoScaleBar (1)
GeoServer (1)
GeoZoomLevel (1)
Explicitly specify GeoZoomLevel to obtain a lower-resolution map rendering:
Explicitly specify GeoZoomLevel to obtain a higher-resolution map rendering:
MaxPlotPoints (3)
GeoContourPlot normally uses all of the points in the dataset:
Limit the number of points used in each direction:
MaxPlotPoints imposes a regular grid on irregular data:

Properties & Relations (10)
Draw contours through general data with ListContourPlot:
Smoothly shade a map using color with GeoDensityPlot:
Use GeoBubbleChart to show values with scaled bubbles:
Use GeoRegionValuePlot to show values with colored regions:
Use GeoHistogram to aggregate locations into bins:
Use GeoSmoothHistogram to generate smooth densities from locations:
Use GeoListPlot for individual locations:
Use GeoVectorPlot and GeoStreamPlot for vector fields:
Use GeoGraphValuePlot to show the values on geographic networks:
