| Sumario: | The objective of this exercise is to face the loss of cognition and therefore the ability to perform geometric transformations from spherical models to ellipsoidal models within the teaching of geography at the undergraduate level. It is postulated that global navigation satellite systems based on reference ellipsoids are still conceived as spherical systems by many students due to the absence of practical examples that help their pedagogical understanding. To cover this gap in this work, the eccentricity, geocentric latitude and geocentric radius of the 90 main parallels of the reference ellipsoid WGS84 were calculated. Methodologically, we worked on a study universe greater than 324 thousand seconds of latitude. Of which only the top 90 cases are shown. Using an analog criterion, the geocentric radius was determined for the ports of Salina Cruz, Oaxaca, Tampico, Tamaulipas and Ensenada, Baja California. As results it is exhibited that the distance to the center of the Earth between Salina Cruz and Ensenada there is a difference of 4 kilometers. |
