KnowGIS.com Introduction to Georeferencing and Image Registration. Image Registration Using ArcGIS Desktop.

In this tutorial, we explore georeferencing techniques, along with transformation methods and resampling techniques. This tutorial uses ArcGIS Desktop and interactive raster and image registration tools. We establish control links, reviews link tables, establish image sources, and the use of vector point data to facilitate image registration.

Before you can match your scanned image to geospatial data you must put it into a coordinate system. This process matches features in your photograph to real world coordinates on the ground.

Many examples are provided on resampling methods, transformation methods, and a discussion of orthorectification are provided.

Raster data obtained by scanning maps or aerial images usually do not contain information that tells where the image fits on the earth's surface. The task of Georeferencing raster data defines where the data lies in map coordinates.

This tutorial is hosted by Jere Folgert.
