“Contour lines are an important way to show the rise and fall of the terrain on a map. They show all places that are at the same height above sea level. They also tell us about the slope of the terrain and are a layer information base in engineering projects “
Contour lines are the most distinctive feature of a topographic map. Contour lines are lines drawn on a map that connect points of equal elevation, which means that if you physically followed a contour line, the elevation would remain constant. …

This repository is a collection of basic scripts — explained in English and Spanish — for analysing landslides using space-based data in Google Earth Engine (GGE). It aims to facilitate working with big data in the cloud as an alternative to using desktop software
