description I'm using [geemap](https://github.com/giswqs/geemap) to display a raster on a created map. This lib use `xarray_leaflet` to display the raster and this lib will end up using `rasterio`

Howdy, I am curious about rasterio's current GDAL version support? Presently, my conda environment is pinned down to GDAL < 3.1

Thanks for your help Sean, I can confirm the black artifacts come from jpeg compression. I also found this answered which explains the problem in

Hi, It looks like your input.tif may have lossy compression applied, and the output will have the same compression by default. You might try rio mask --overwrite --crop in.tif out.tif --geojson-mask

Dear Rasterio developers and users, I' m masking geotiff files with geojson polygons: rio mask --overwrite --crop in.tif out.tif --geojson-mask mask.geojson Unfortunately after doing so black

Hello Sean, Sorry for abandoning the post. I installed rasterio via pip, and recently i had to reinstall my OS, and also of course rasterio, and the problem still persists. I will prepare a demo and

Thank's Amine. I create a function to resample the raster keeping the extents and resolution to calc with other rasters.

Hi Sean, I’ve tried using os.environ and also env_variables in my app.yaml. Is there a better way that you know of to set the aws access keys? From: <main@rasterio.groups.io> on behalf of

Sean, Sorry, I’ll try to be a bit more explicit. I’m getting the following error after setting the keys in my app.yaml file. I’m entirely sure what it means but wonder if it has something to do

Hi, Excellent! Yes. The important detail is that the transform matrix passed to xy() must apply to the window. You can't use the matrix from the dataset's .transform attribute unless your window has

Worked it out using a previous thread, doing it using an affine transform on the window. I would however like to know if the rasterio.transform.xy method can be used when passing col, row from a

Does a window generated by rasterio maintain the dataset origin and absolute col/row indices? I'd like to be able to iterate over a window of a dem dataset, find the highest value in the window and

You can't sum rasters with different shapes. Resample your rasters to a common resolution and align them so that they can be read as arrays with the same shape, then add the two arrays together and

Hi, I'm developing a system and I need sum two raster with different shapes. I've a DEM raster with a resolution of 30 meters and another raster with a resolution of 10 meters, both clipped in the

Hi, You can also use skimage package, it has a filters module with threshold_otsu. Hope it helps, JL -- Jaime Lopez Carvajal

hi Jaime, thanks for your reply. Do you know if there is Otsu segmentation in rasterio? Or should I use f.e. OpenCV?

Hi, It seems to me that you can apply Otsu segmentation first to every image, to detect the threshold. Then you can use the threshold as a mask's parameter. Sorry, if I could misunderstood the

Dear Rasterios, beeing quite new to rasterio I'm looking for help regarding the following: I've a large amount of 1 Channel Satellite imaginary. While the data contains no-data information around the

Hi Judson, If the source data for your App Engine app is on AWS, you'll need to make sure that you're providing AWS keys to access it. You'll want AWS_SECRET_ACCESS_KEY = secret_access_key
