I have a long list of data (over 1,000,000 points) in the following format.
data={{36.4045, 127.977, 3.64633}, {36.4042, 127.989, 3.64633}, {36.404,
128., 2.73436}, {36.4038, 128.011, 2.36786}, {36.4035, 128.023,
3.15759}, {36.4033, 128.034, 3.15759}, {36.4031, 128.046,
2.73436}, {36.4028, 128.057, 2.05048}, {36.4026, 128.068,
2.05048}, {36.4024, 128.08, 1.77565}, {36.4021, 128.091, 1.53765}};
GeoGraphics[{{Blend[{Red, Blue}, #3], PointSize[.001],
Point@GeoPosition@{#1, #2}}} & @@@ data,
GeoProjection -> "Mercator", Frame -> True,
GeoScaleBar -> "Kilometers", GeoRange -> {{0, 60}, {100, 170}}]
The first two columns are latitude and longitude respectively, and the third column is the data value on that coordinate. How do I plot these data with different colours based on the date value on a geographic map in Mercator projection?
I am able to plot such geographic map with the above code. However, maybe there are too many points that the calculation is very time consuming or the Kernel even quits during evaluation.
Many thanks in advance.
