Rasterio's general discussion group is open for business
Greetings,
Questions about installation, distribution, and usage of Rasterio are welcome here. Issues opened in Rasterio's GitHub repo that fall into one these categories may be perfunctorily

Does rasterio load data into memory while reprojecting?
Hi there!
I have a general question about reprojection. Consider the following example:
with rasterio.open(fname_src) as src:
with rasterio.open(fname_dst, 'w', **kwargs) as dst:
for i in

Re: Does rasterio load data into memory while reprojecting?
Hi Denis,
Yes, you can warp arbitrarily large rasters when you use rasterio.band(). The warper chunks the work so that its working arrays are no more than 64 MB in size. You can increase this limit

Hello everyone,
I’m a new member of rasterio group willing to know more about rasterio and satellite image processing. I’m also new in programming, so, don’t be surprised if I make weird

Plugin for common color maps?
Hey there,
Thanks for a great library - I've just been getting into it via the rio-tiler library where I'm building an app for showing imagery in combination with stream gauge data (see below).

Calculate transformation using output dimensions
In gdalwarp we have at least two options for managing of output size of a raster:
-tr xres yres: set output file resolution (in target georeferenced units)
-ts width height: set output file size in

Re: Calculate transformation using output dimensions
Looks like you are most of the way there.
If you have a dataset open with `rasterio.open`, then you should be able to get the information you need for the input:

Thanks for reply.
I could not find what I need in rasterio and have created PR: https://github.com/mapbox/rasterio/pull/1409

LERC Compression Error

I have a raster that uses LERC compression. Opening/reading from the raster works fine, however I get the following error when trying to access the `.profile` property:

Hi Caleb,
Sure, a PR would be welcome. This compression algorithm isn't available in a GDAL release yet, but it doesn't do any harm to have it enumerated in Rasterio. Behavior for Rasterio 1.0.0 and

Reproject with mask preserving
Hi there!
I have GeoTIFF files with internal mask and I need to reproject them and not lose mask.
I've found that direct generating warped mask band is not supported by GDAL:

Re: Copying Rasterio crs from input to output dataset
My GDAL_DATA env var wasn't set.
Explanation:
I was running the code within the PyCharm IDE that supposedly supports conda envs but doesn't actually *activate* them properly. There are init scripts
