Open QGIS and locate the downloaded files in theBrowserpanel. Expand individual zip files to show the.hgtfiles. Hold theCtrlkey and select all individual files. Once selected, drag them to the canvas. You will see 11 individual layers loaded in theLayerspanel and displayed in the canvas. We...
Right-click your layer in the contents panel. Next, select Data > Export Raster. From here, you’ll have to export it to a directory of your choice. Also, make sure to allow there to be NoData in the output raster. Why clip rasters? Clipping rasters means that you can save time. ...
9.Raster Processing– Raster processing is a “catch-all” term used to transform existing grid data into new outputs. Common raster processing tasks include selecting, clipping, and splitting raster datasets. 10.Interpolation– Interpolation techniques estimate unknown values based on existing sample po...
There is a difference for example the WxH size is slightly different, and it seems that is caused by the clipping operation because if I load in QGIS 3.10.3 the layer clipped in 3.2 the WxH is 12027x7001. I'm not sure if this is enough to justify the different results you are seeing...
Anyway: https://issues.qgis.org/issues/19594#note-14 Yes, clipping the merged DEM to that polygon gives the result I'd expect. What failed for me was using that function to clip each of the individual DEM files to their useful fragments before merging them (in the hope of avoiding the...
ST_Cliphas many optional arguments. One worth mentioning iscrop, which defaults totrue. With the default setting, the extent of the new raster is the extent of the intersection of the raster and the clipping geometry. If you pass infalse, the dimensions of the new raster will be the same...
How do I join layers in QGIS? How do I group layers in QGIS? There are two ways to do this: Press the icon to add a new group. Type in a name for the group and press Enter . Now click on an existing layer and drag it onto the group. ...

To make this process as efficient as possible, I have created the option of specifying WKT strings as clipping boundaries. This allows us to select individual features using the QGIS Copy Features command and paste the WKT string into the "Enter Cutline WKT" edit field....
In the Clipping mode section, choose Mask layer. Select the newly created brazil_boundary as the mask layer. Check the box next to Load into canvas when finished. Click OK. The new cropped layer will be loaded into QGIS. You will notice the black pixels surrounding the actual mosaic. Let...
