Sumario:Bogota’s Vertical Reference Network has been developed using first order methods of leveling (Spirit Leveling) on its main roads, in around 150 kilometers, with more than 80 benchmarks distributed in whole city. Data Processing, to data acquired between July and august of 2007, shows a systematic variation in heights in some zones of the city about acquired data in 2003 and 2005. In addition, permanent and detailed monitoring of Bogota’s GNSS-network supports constant ground subsidence in almost whole City.
