In this video GNSS technology foundations and use are explained, and also how it is used in mobile  and in other more accurate applications, such as cartography or Earth dynamics knowledge. The video includes a test as a quiz to check what has been learned, which can be found in the descriptive text located below it.  https://www.youtube.com/watch?v=LA3KeMDFIhQ&feature=youtu.be

The aim of this interactive teaching and learning resource is to learn to measure the distance between two geographical points on a map and to find out the height difference and the slope between them. With a chosen starting point and destination point, the contour lines are interpreted and a simple calculation is made. Aimed at students aged from 10 to 14 years.  https://www.ign.es/recursos-educativos/descubre-territorio/desnivel.html

Este recurso interactivo y didáctico tiene como objetivo aprender a medir sobre un mapa la distancia entre dos puntos geográficos y conocer el desnivel y la pendiente que existe entre ellos. Con un punto de partida y otro de llegada elegidos, se interpretan las curvas de nivel y se realiza un sencillo cálculo. Dirigido a estudiantes de edades entre 10 y 14 años. Actualizado en 2020. También se ofrece este recurso en inglés. https://www.ign.es/recursos-educativos/descubre-territorio/d...
