Geodetic work executed in Mexico from April 1949 to March 1950

Abstract

The activities in this field of operations are concentrated in three arcs of triangulation, one which is being extended along the 101st meridian, one projected in the Slates of Oaxaca and Chiapas to the Guatemalan border, and one along the 103rd meridian in its tie with the 26th parallel. The respective diagrams for these triangulations have been published in previous reports [Medina, 1950, and earlier reports], and I am therefore going to limit my discussion to the progress on the stations affected in each of the arcs.
