312203596 MDU6SXNzdWUzMTIyMDM1OTY= 2042 Anyone working on a to_tiff? Alternatively, how do you write an xarray to a geotiff? ebo 601025 closed 0     31 2018-04-07T12:43:41Z 2022-04-09T03:14:41Z 2022-04-09T01:19:10Z NONE      

Matthew Rocklin wrote a gist https://gist.github.com/mrocklin/3df315e93d4bdeccf76db93caca2a9bd to demonstrate using XArray to read tiled GeoTIFF datasets, but I am still confused as to how to write them to a GeoTIFF. I can easily create a tiff with "rasterio.open(out, 'w', **src.profile)", but the following does not seem like the best/cleanest way to do this:

``` ds = xr.open_rasterio('myfile.tif', chunks={'band': 1, 'x': 2048, 'y': 2048}) with rasterio.open('myfile.tif', 'r') as src: with rasterio.open('new_myfile.tif', 'w', **src.profile) as dst: for i in range(1, src.count + 1): dst.write(ds.variable.data[i-1].compute(), i)

``` Also, if the profile and tags were propagated through open_rasterio, then the second open would not be necessary and would be generally useful.

315149637 MDU6SXNzdWUzMTUxNDk2Mzc= 2065 how do you flatten an xarray? ebo 601025 closed 0     5 2018-04-17T17:01:35Z 2018-05-18T05:14:31Z 2018-05-18T05:14:31Z NONE      

I got a version of TomAugspurger's Spectral Clustering modified to work with GeoTIFFs http://localhost:8839/notebooks/geo-spectral-geotiff-da.ipynb, and I have been working to modify it to run using xarrays http://localhost:8839/notebooks/geo-spectral-geotiff-xa.ipynb.

I'm currently stuck on getting the xarray flattened/reduced. I keep getting errors similar to: "TypeError: 'axis' is an invalid keyword argument for this function" no matter what I have tried. I need to find some way to change the array into nbands x (1 x N). I have not been able to figure out how to do this via the examples or docs I've read.

Suggestions? Also if you have other suggestions on how to clean up either example let me know.

Also, these are using publicly available data and will be free to post some place if desired.
