Talk:Pico Bolívar

Untitled
Elevation is 4981 m not 5007 m.

"In 1993, investigators Heinz Saler and Carlos Abbot determined, through the system of global positioning GPS(satelite), that the true altitude of the mountain is of 4,980.8 meters"

Hello ::

The correct altitude: 4978.

The GPS laboratory of the Department of Geophysics of the University Simon Bolivar finally gives the value sought for so many years, after nearly three years of analysis and processing of the acquired data in the Pico Bolivar by Diego Deiros and Carlos Rodrigues from the mentioned University  and  Napoleon Hernandez from the Government Agency of National Cartography, agency that validates all measurements. Although this was reported by several newspapers, the first official information is given in 2003 by Government through a Informative Boletin from National Cartography Agency (IGVSB).

Description: v. : Il. ; 31 cm. Topic (s): Geography Venezuela, Newspaper publication. Public Document Signature: 910.6087. Barcode: 2013 590168.

In 2005 after a much more rigorous analysis and processing of the same data obtained in 2002 It was reported to the scientific community in the paper:

Pérez O, Hoyer M, Hernández J, Rodríguez C, Márques V, Sué N, Velandia J, Deiros D. (2005). "Alturas del Pico Bolívar y otras cimas andinas venezolanas a partir de observaciones GPS" Interciencia. 30 (4)

In addition the most precise and accurate valor so far dated. To be exact is 4978.4 m, with an error of ± 0.4 meters.

Note:

There are many measurements. Notably absolute measurements with one frequency GPS receivers, could provide near real values, but are by coincidence, because errors are very high.

For scientific purpose the data must be acquired with an appropriate methodology, for long periods of time, with multiple GPS equipment, more than one frequency, differentially and they must be corrected by postprocessing using data from the base stations, with precise ephemeris and eliminating errors ionosphere, troposphere, etc.

The oldest measurement mentioned before, as it indicated in some paper and reports, although it was of great scientific contribution but was not validated by National Cartography Agency.

Correct name
Hi everyone!

The Dr who suggested the name for the mountain was Tulio Febres Cordero not Miguel Febres Cordero (indeed Miguel died 5 years before the name had been suggested)

Is not possible that Miguel Febres Cordero proposed the name in 1925 because he died on February 9, 1910. Probably the correct information would Tulio Febres Cordero. But also I can not find a real reference to prove it, perhaps another Wikipedian can help find. Tulio refers in his letters in 1928 to the peak as: "today Bolívar". It makes clear that the name was changed shortly before 1928.Biographer1950 (talk) 18:12, 26 August 2016 (UTC)
