I'm referring to this question&discussion: How do I create a shapefile showing footprints of Rasters?
I need to create the polygon outlines of several single layer raster images, not the extent/bounding box, but the area without the nodata values, as shown here: How do I create a shapefile showing footprints of Rasters?.
In the answer to to post above, the Image Boundary plugin was mentioned, however, I don't find it in the QGIS 1.8.0 Lisboa, running on Ubuntu?
Is the tool still available?
If not, is there a way to do this using opensource tools, either gdal, R, QGIS, GRASS, or similar, not with ArcMap?
Thanks!
