EDIT gdaldem seems to be the right tool for your task: Take a raster of your choice (like SRTM as an example) Create the following text file named col.txt: 0 black 100 blue 200 yellow 300 orange 400 …

Gdalwarp is the tool to reproject, you find it in Qgis under Raster->Projektionen->Transformieren or standalone in OSGEO4W. …

Your attempt is designed to fail. If you look at the image, you see the data arranged as a circle, with black triangles in the corners of the square, where the satellite view goes right into orbit. In …

See this tutorial: http://www.slideshare.net/shencoop/qgis-raster-to-point If you want a less densified point file, try this tutorial: http://www.gistutor.com/quantum-gis/19/54-how-to-sample-raster-datasets-using-points-in-quantum-gis-qgis.html …

The result is a virtual raster file, which you can edit with a text editor to adjust the parameters if needed. …

For a large-scale map, it does not really matter if the latlong coordinates are based on Pulkovo datum or WGS84. The longitudes seem to be based on Greenwich (not Ferro that was used before). So you …

Raster > Projections > Warp is dedicated for rasters. The reason behind are the many options you may need for reprojecting (and resampling) raster data. …

gdal_translate is able to extract single bands: gdal_translate -b 1 in.tif out1.tif gdal_translate -b 2 in.tif out2.tif gdal_translate -b 3 in.tif out3.tif gdal_translate -b 4 in.tif out4.tif Raster - …

This way it works: unselect your vector data, to show only the Openstreetmap background File -> Save as Image Load the image as raster, set EPSG:3857 as CRS Delete the Openstreetmap background layer … in step 3 Raster -> Extraction -> Clipper check Mask layer with the vector data, and add the result to the canvas Remove the unclipped raster layer from step 5 EDIT If you want the clipping for all …

For the Mercator projection, the extent can not reach North and South pole for mathematical reasons. The standard Google and Openstreetmap mercator projection is limited to 85.011° North and South to …

I tried the 3b31 hdf file from mirador and found the same orientation as you encountered. So I created some GCP to perform a rotation anti-clockwise: gdal_translate -of VRT HDF4_SDS:UNKNOWN:"3b31.hdf …

you can convert a WGS84 raster of bluemarble to an ortho projection with this command: gdalwarp -overwrite -dstnodata 0 -ot Byte -s_srs "+proj=longlat +R=6371000" -t_srs "+proj=ortho +lat_0=30 +lon_0= …

You can always save the current view as georeferenced image, and use that with gdal. Although it is only screen resolution and size, maybe not what you want. Alternatively, you can input WMS data dir …

You have to decide whether you want to enter coordinates in lat/lon, or from a background map with a projected CRS (e.g. in metres). For the first choice, you have to set the target CRS to WGS84 (EPSG …

Raster -> Conversion -> PCT to RGB is one way to do that inside QGIS. gdal_translate -expand rgb is another. …
