Powers of Ten Geography

Make sequences of maps that zoom out by 10x at each step.

Run the code to show a 100-meter disk around the Eiffel Tower. Try sizes other than 100 meters:

SHOW/HIDE DETAILS

The Eiffel Tower has an exact representation in the Wolfram Language that you can get using plain English. Type += to get an input box, type eiffel tower, and run the code:

In[1]:=
X
Out[1]=

You can use += inside of other code. And you can use it to get values with units, like 100 meters.

This makes a map showing a 100-meter disk around the location of the Eiffel Tower:

In[2]:=
X

Table makes lists of things.

Heres a table of the powers of 10 from 2 to 7:

In[1]:=
X
Out[1]=

This uses Table to make a list of maps with disks that increase in size in powers of 10 from 2 to 7:

In[2]:=
X

Use the Lambert Azimuthal map projection. Try some other projections, like Albers, Mercator, or Mollweide:

SHOW/HIDE DETAILS

This is the last map in the series in the previous step. The disk doesnt look like a disk because the map projection distorts it:

In[1]:=
X
Out[1]=

Use a LambertAzimuthal map projection to get a disk that looks like a disk:

In[2]:=
X
Out[2]=

Here is a list of some of the more common projections:
