We have calculated different measures of bilateral distances available for most countries. GEOSEARCH one of the useful, strong and most used command.
GEODIST ARMENIA ISO
There are firstly three identification codes of the country according to the ISO classification, the country's area in square kilometers, used to calculate in particular its internal distance. Description Format Source References Examples. GeoDist provides several geographical variables, in particular bilateral distances measured using citylevel data to assess the geographic distribution of population inside each nation. GEODIST Command, Indicates the distance relative to the two members and units of the specified key. In cepiigeodist: CEPII's GeoDist Datasets. For example, Iowa City will be paired up with every city in the distance.dta file as will Boston, Houston and Chicago. GeoDist makes available the exhaustive set of gravity variables used in Mayer and Zignago (2005). R-devel: geodist_0.0.8.zip, r-release: geodist_0.0.8.zip, r-oldrel: geodist_0.0.8.zip This command will create all possible pairs of the cities in the two files.

Includes the reference nanometre-accuracy geodesic If the value is expressed in degrees, it must be between 90 and 90. Coordinates that are located north of the equator have positive values coordinates that are located south of the equator have negative values.
