The top section where the image will be displayed and the bottom section where a table showing your GCPs will appear. Now we will open our JPG image. Go to File ‣ Open Raster. Getting Started.

It is fundamental to geospatial technologies in general, and geographic information system (GIS) in particular. Depending on the spatial resolution in effect, georeferencing mechanisms can be generally classified into metric Georeferencing GDAL and the Install plugin button. It will now be added under Raster. 3. Georeferencing a Historic Map a.
