ALT An educational infographic titled "Coordinate System in GIS" that visually compares Geographic Coordinate Systems (GCS) and Projected Coordinate Systems (PCS). The image is divided into two main columns: Geographic Coordinate System (GCS): The left side features an illustration of a 3D globe with grid lines representing latitude and longitude, highlighting a specific point labeled with the Greek letter lambda for Longitude. Text below explains that a GCS is based on the Earth's spherical surface and uses degrees as its units of measurement. Projected Coordinate System (PCS): The right side shows a flat, 2D map grid overlaid onto a landmass and ocean scene, marking a specific point with "X Easting" and "Y Northing" coordinates. The text below describes a PCS as being based on a 2D flat surface (map) and using linear units such as meters or feet. The graphic attributes its source to GISRSStudy at the bottom left corner.

ALT An illustration depicting a university campus scene under a dark purple sky. In the background stands a large, symmetrical, yellow university building with classical columns and the word "UNIVERSITY" written across the pediment. Green pine trees are scattered in front of the building along a winding path. In the foreground, three students are sitting on a light-colored lawn, dressed in yellow and dark grey clothing that matches the scene's color palette. On the left, a student sits looking toward the center while holding an open book. In the center, another student is viewed from behind, facing a third student on the right who is sitting cross-legged and also reading an open book.
