I am pretty new in QGis and I encounter the following problem.
I have 2 rasters, let's say, "cadaster" and "tranchot". The raster "tranchot" was georeferenced from the raster "cadaster" with QGis. After the georeferencing, QGis shows the 2 rasters perfectly superimposed and built on the same projection.
Today, I want again to superimpose this 2 rasters but "tranchot" looks like a thumbnail in the corner of "cadaster". From the metadata, the pixel makes 0.1143 meter for "cadaster" and 0.02831 meter for "tranchot".
Probably there is an handling to be done in QGIS to superimpose these two rasters, probably simple, yes, but which one ?
In the future, I'll need to compare vectors from "cadaster" with the raster "tranchot". Is there a mean to make rasters and vectors superimposable permanently ?
Many thanks in advance for your help
