I'm following a web tutorial at lynda.com about QGIS. In one of the first videos I see there's this preview of raster files.
.dem files and the
.ecw files among the tutorial example files. I can preview the
.dem files as in the video, but unlike the authors of the tutorial I cannot preview the
Additionally, when I try to open a
.ecw file with qgis (not qbrowser), I get the following message:
The layer whateverthepathis/552B.ecw is not a valid layer and can not be added to the map
When I open a
.dem file instead, no error message is displayed and the layer is added just fine.
Is there something I need to setup in order to be able to preview those files and add their layers to the map? Is it a bug of this particular version?
I'm just getting started with qgis and with GIS software in general.
