Geographic Coordinate Systems (GCS) What is the Geographic Coordinate Systems? A Geographic Coordinate Systems (GCS) is a system that uses a three-dimensional spherical surface to determine locations on the Earth. The GCS is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth at latitude and longitude. The GCS consists …
Ground Control Points (GCPs) What is Ground Control Point? The Ground Control Points (GCPs) are defined as points on the surface of the earth of a known location used to geo-reference data. The GCPs are specific pixels in an image for which the output map coordinates are known. GCP consists of two X,Y pairs of …
Online Georeferencing What is Georeferencing Georeferencing is a Coordinate system of a digital map to a ground system of Geographic Coordinates. A Georeferenced image has been to a known Earth Coordinate system, that is Latitude (Y) and Longitude (X). This term is commonly used in the Geographic Information System (GIS). In this case, GIS Software …
