METODOLOGIA DE PUNERE ÎN PRACTICĂ A GEOREFERENŢIERII UTILIZÂND TRANSFORMAREA AFINĂ

Abstract

Georeferencing is the process of converting a image in file coordinates or page coordinates to a file in map coordinates in a specific map project, coordinate system, map projection and datum. For example, a scanned map can have an origin point and a raster association where each point on the map is identifiable by it's file coordinates. In order to georeference an image, you need to identify map coordinates of any 3 points on the map. There are two main methods of registration: one method is to manually type in map coordinates for points, then select those points on your image, another method is to bring up
a coverage that is registered and that has features in it that are visible in the scanned file to register.
