Geodetic Control Point

Township 13S, Range 15E, Index Code X15


All horizontal data based on NAD83 (HARN92). All CORS users should read Use of Geodetic Control Points with NGS Datums first.

This geodetic control point is, at best, third order and is not a horizontal control point as defined by ARS 33-133. A monument existed at the time the geodetic position was determined. The monument that existed may have been in the proximity of, or may in fact have been, an aliquot corner, or a section corner. The survey which determined the geodetic positions was for the purpose of controlling the City of Tucson and Pima Association of Governments Orthophoto Project, not for determining whether the monuments represented aliquot corners, or section corners nor to establish horizontal control. Also, read the Pima County ITD GIS Disclaimer.
