I am new to QGIS but used to ArcGIS. I am working my way through the tutorial and have downloaded a map from earth explorer - following all the instructions. The map is in the left hand panel and the co-ordinates are visible. A thumbnail is showing in properties.

I have tried zoom to image but no map appears.

I cannot continue with the tutorial until I get the map!

  • That did it! - so what is CRS – JayC Nov 12 '14 at 16:31

Make sure that the Coordinate Reference System (CRS) is the same for the layer you want to view and the projected CRS.

To give a brief description, a CRS is used to project objects and locations on a map. There are 2 types of CRS ( both quoted from this source):

  • Geographic coordinate system which contains locations defined in terms of the position on a globe using latitude and longitude values.

  • Projected coordinate system which contains locations defined using Cartesian x, y coordinates on a flat, two-dimensional surface.
