Contains gtapdists.har, where header  DIST shows distances between all 113 GTAP 7 regions.
TEST.BAT runs MapDist.tab to compute the distance matrix for an aggregated region set.

The distances were computed by Tom Rutherford as described in gtapgeo.pdf;
The data he used is contained in the larger file geodata.har (warning: opens slowly in ViewHAR).

To aggregate distances, MapDist.tab uses the same city population weights used by Rutherford
to compute inter-country from inter-city distances. However, you could choose to use other weights
(eg, GDP or trade weights).
