Your data appears to be observational data, with a lat, lon value given for the position (of a given spacecraft maybe?) at that time step. where ( xda != nodata_val Understand how rioxarray extends Xarray for geospatial data handling. open_rasterio. I want to set those values to NaN and then use nearest neighbor interpolation to resample the data and It’s unfortunately also very common to come across GeoTIFFS where the nodata value is not specified in the metadata, so you have set it via xarray or np. whl; Algorithm Hash digest; SHA256: 64cc571807204afc1ffaf5f9a0a2640dccb1e2edd602d952a3c65153b6645540: Copy : MD5 You can learn how to clip, merge, and reproject rasters in the Usage Examples section of the documentation. tif", compress='LZW', tiled=True, dtype="int8") with There currently isn't support for masks in rioxarray. If nodata == None, then a default value is used based on data type. Replace some values in DataArray based on list of indices. mask if possible. import rioxarray import xarray as xr #Sentinel-5P data xds = xr. The method docstring gives the following warning: dset rioxarray's read_rasterio method correctly loads the metadata, but returns a data array and treats all data variables and my time dimension as bands (in one single dimension) import rioxarray as rxr xds_rio= rxr. DataArray. clip using a xr. As we saw before, there also exists a method called reproject(), which only reprojects one raster to another projection. Parameters: input_nodata (Optional[float]) – Valid nodata for dtype. This is due to how xarray handles integer masks: pydata/xarray#1194. Perform basic geospatial operations, such as I get the following error when trying to clip a GeoTiff to a shapefile: "No data found in bounds.
