Abstract

This article describes an alternative methodology for determination of the geoid undulation on an area of ​​4x4 minutes of arc around the Escuela de Topografía, Catastro y Geodesia in the Universidad Nacional, Costa Rica. The proposal requires to make GPS and conventional altimetry measurements in a three-dimensional network established for this purpose. The elaborate measurements allow to determine the geoid undulation as the difference between of elipsoidic height and orthometric height. The results will serve to know the behavior of the geoid for the area, which is going to be compared with calculate undulations coming from the application of the Carib97 model that covers the Caribbean Sea. At present only 80% of the net has been calculate. In order to determine the geoid undulations, now it is doing the first tests.
