Geodetic Operations in the United States, January 1, 1936 to December 31, 1938

摘要

Although considerable advances have been made in the geodetic operations in this country during the period covered by this report, they are much smaller in scope and volume than for the 3-year period immediately preceding. There is much evidence, however, to show that interest in such geodetic surveys as first- and second-order triangulation and leveling is not decreasing, but has steadily increased during the period. Requests for data resulting from such surveys, already heavy at the beginning of the period, continue to grow from year to year. This is not at all surprising when one considers the function of geodetic work in its practical application to problems of engineering which are dependent upon accurate surveys and maps, such as flood control, reclamation work, highway planning, and for scientific investigations and studies which must often precede or go hand in hand with the engineering plans.
