GIS or Geographic Information System is the collection, visualization, andanalysis of geographical or spatial data. In this section, we will cover thedata types commonly used in GIS applications.
Vector data represent objects on the Earth's surface using their longitude andlatitude, as well as combinations of the pairs of coordinates(lines, polylines, polygons, etc.).
Raster data represent objects/variables on the Earth's surface as a matrix ofvalues, in the form of pixels, cells, or grids.
Introductory video Code editor What is Earth Engine? 1. A cloud-based platform for planetary scale geospatial analysis 2. Uses Google's computational resources to reduce processing time 3. A massive archiveof remote sensing data
Declaring variables
A container object (usually in the form ee.SomeVariableType) is used to wrap anative JavaScript object so that Google's servers can perform operations on it.
Displaying metadata
The printoperation is also useful for printing data and getting debugginginfo. Note: You cannot print more than 5,000 elements at once.

Features are geometries associated with specific properties.Feature collections are groups of features.Finding the area of a geometry
By default, all units in Earth Engine are in meters.
Reducers are objects in Earth Engine for data aggregation. They can be used foraggregating across time, space, bands, properties, etc. Reducers range frombasic statistical indices (like ee.Reducer.mean(), ee.Reducer.stdDev(),ee.Reducer.max(), etc.), to standard measures of covariance(like ee.Reducer.linearFit(),ee.Reducer.spearmansCorrelation(),ee....
