Visualize Earth's Gravitational Field

Use

to obtain the gravitational field magnitude across the world:

In[1]:=

data=GeogravityModelData[{{-90,-180.},{90,180.}},"Magnitude",GeoZoomLevel-2]

Out[1]=

QuantityArray

Dimensions: {32,64}

Unit:

Meters

2

Seconds



Calculate the points corresponding to those values:

In[2]:=

points=Flatten[#,1]&/@GIS`GeoPositionArray[{{-90,90},{-180,180}},GeoZoomLevel-2]

Out[2]=

GeoPosition

Number of points: 2048

Lat bounds: {-87.2,87.2}

Lon bounds: {-177.,177.}
