Using a laser scanner attached to an aircraft, we carpet the terrain below us with pulses of lasers, collecting billions of points. The rulers moved to new, more compact cities in the Phnom Penh area, where the current capital of Cambodia still stands to this day. Compared with more compact city forms, they were certainly rarer and more prone to disappear from a region.

The rulers moved to separate locations.
( z0 move :ARG0 ( z1 person :ARG0-of ( z2 rule ) ) :ARG2 ( z3 location :ARG1-of ( z4 separate ) ) )
(z0 / move-01
    :ARG0 (z1 / person
              :ARG0-of (z2 / rule-03))
    :ARG2 (z3 / location
              :ARG1-of (z4 / separate-02)))
The rulers moved to separate locations .
z1 :ARG0-of z2
z0 :ARG0 z1
z3 :ARG1-of z4
