Georeferencing



In this activity we learned how to manually add geographic referencing to unreferenced dataset. First of all we opened the georeferencing tool and then added an unreferenced raster and an already referenced dataset showing the same area.Hence, the fit to display feature was used in order to bring the layer you want to reference into the current area that was viewing and manipulated data. Moreover, identification of features present in both layers and the control points feature was used to create links.  Also the total RMS errors was review and some changes made when it needed. Finally we chose a transformation type and update our georeferencing data.
