Detailed explanation-1: -Georeferencing is the process of aligning satellite imagery or other types of maps with real-world geographic coordinates. In simple words, it involves taking an image of the Earth’s surface, and placing it accurately on a map of the same area.
Detailed explanation-2: -Georeferencing is key for a Geographical Information System (GIS) to succeed with its ambitions to analyse and manage different types of data. Whether it’s remote sensing, imagery, or satellite data, georeferencing connects the information to a map displaying it in relation to its position in the real world.
Detailed explanation-3: -Georeferencing can be divided into two types: vector and raster referencing. Figure 1 shows a classification approach of the types of georeferencing.
