In GIS, a Projected CRS (Coordinate Reference System) is a system used to represent locations on the Earth's surface using a two-dimensional Cartesian coordinate system. Unlike Geographic CRSs, which use latitude and longitude, Projected CRSs employ x and y coordinates on a flat plane to represent geographic locations. Here's an overview of the key aspects of Projected CRSs: 1. Conversion from Geographic CRS: Projected CRSs are derived from Geographic CRSs through a process known as map projection. Map projections mathematically transform the curved surface of the Earth onto a flat plane, resulting in distortions in shape, distance, area, or direction. Different map projections are designed to minimize specific types of distortion, depending on the intended use of the map. 2. Planar Coordinate System: Projected CRSs use a two-dimensional Cartesian coordinate system, which consists of horizontal x and vertical y axes. The x-axis typically represents east-west coordinates, while ...

In GIS, a Geographic CRS (Coordinate Reference System) is a system used to define and represent locations on the Earth's surface using latitude and longitude coordinates. It is based on the concept of a three-dimensional ellipsoidal or spherical model of the Earth. A Geographic CRS provides a framework for accurately specifying the position of a point on the Earth's surface by assigning numerical values to latitude and longitude. Here's a brief explanation of the components and characteristics of a Geographic CRS: 1. Latitude: Latitude measures the distance north or south of the Earth's Equator. It is expressed in degrees, with values ranging from -90° at the South Pole to +90° at the North Pole. The Equator is defined as 0° latitude. 2. Longitude: Longitude measures the distance east or west of a reference meridian. The most commonly used reference meridian is the Prime Meridian, which passes through Greenwich, London, and is assigned a value of 0°. Longitude values ra...

In the context of Geographic Information Systems (GIS), CRS stands for Coordinate Reference System. A Coordinate Reference System is a framework used to define and represent locations on the Earth's surface in a consistent and standardized manner. The Earth is a three-dimensional object, and in order to accurately represent locations on its surface, we need a system that defines how coordinates are measured and referenced. A CRS provides a set of rules, parameters, and mathematical formulas to define the coordinates of points on the Earth's surface. There are two main types of CRSs used in GIS: Geographic CRS and Projected CRS. 1. Geographic CRS: A Geographic CRS, also known as a geodetic CRS, uses latitude and longitude to define locations on the Earth's surface. Latitude measures the distance north or south of the Equator, while longitude measures the distance east or west of a reference meridian, typically the Prime Meridian (0 degrees longitude) that passes through Gree...
