I have scanned about 200 aerial photographies and want to georeference these to fit the area they are covering. I'm using the Imagery basemap, because this is the only free georeferenced map I have found of the area.
This basemap is a very big file, covering the whole world. For my project i only need a small part of Greenland. Does anyone know if it is possible to crop this map to only cover my area of interest?
Second question, when i georeference one picture and rectify this it is saved so that I can close and open it again. But when i try to put another picture in the same file and georeference the second picture, the first one snapps back to original position.
Is it possible to georefernece several pictures in the same file, to make them fit together?
Hope to get a quick answer!
