| contents | Comparison of three surveying techniques applied to hydrogeological studies: level, barometer, and GPS Xyoli Pérez E. Rangel Luis E. Marín Ciencias de la Tierra GPS level Surveying barometer hydrogeology The error from three different surveying techniques- level, hand-held barometer, and hand-held GPS-were compared in terms ofaccuracy and cost effectiveness for hydrogeological studies by surveying a four-kilometer circuit within the campus of the UniversidadNacional Autonoma de Mexico.The polygon was surveyed once with the level and the barometer, and twice with GPS. Vertical errorswere 17 mm, 13 meters and 114 meters, for the level, barometer and GPS, respectively. Of the three options, the first is by far the mostexpensive. Thus, the preferred method for height determinations continues to be the level, even if it is the more expensive option. 1998 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56837207 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.37 |
