Geo-Referencing

Geo-referencing

Hey guys:

This activity covers methods to manually add geographic referencing to an unreferenced dataset and to create geographic data from non GIS ready maps and photos. The basic process for georeferencing a photo which we did is as follows: 

First - We added an unreferenced raster and an already referenced dataset showing the same area.

Second - We used the fit to display feature to bring the layer we wanted to reference into the current area we were viewing and manipulated data.
Third - We identified features present in both layers and used the add control points feature to create links.
Fourth - We reviewed our total RMS errors and made changes as needed.
Fifth - We chose a transformation type and update our georeferencing data.
