Is there in Rasterio any way to create a mosaic?
I tried to google it, but I couldn't find anything, maybe someone else already used it.
I want to use some open source possibilities, I already know of possibility to use gdalmerge, gdalwarp.

Rasterio's rio warp
command (see https://github.com/mapbox/rasterio/blob/master/rasterio/rio/warp.py) can be used to make image mosaics. With a little work you could use that function in Python code, not just as a command line program.
import rasterio
import numpy as np
from rasterio.merge import merge
from rasterio.plot import show
src1 = rasterio.open('/path/to/your/raster1')
src2 = rasterio.open('/path/to/your/raster2')
# Taking a peek to make sure these are the rasters you want...
show(src1)
show(src2)
srcs_to_mosaic = [src1, src2]
# The merge function returns a single array and the affine transform info
arr, out_trans = merge(srcs_to_mosaic)
show(arr) # Check to make sure the merge looks good.
I was just looking for a similar technique and found this method based on the rasterio/merge.py function given here.
You can check out my example with two orthomosaic images here.
However, I'm not sure this is the best method...no doubt the dude himself @sgillies has more insight into this!
merge
from therasterio.merge
module, orrio merge
from the command line. – Loïc Dutrieux Jul 11 '17 at 16:50rio merge
without the dash.rio --help
will give you the list of all CLIs, andrio merge --help
will give you more specific help for that command in particular. – Loïc Dutrieux Jul 11 '17 at 17:49gdalwarp
instead. It does mosaicking, reprojecting/resampling all at once. – Loïc Dutrieux Jul 11 '17 at 19:45
