Re: Create a Dataset from an array

Sean Gillies

I feel it's too early to make a new function for this. First, I'd like to try to use this to eliminate the copying of data inside InMemoryRaster.

Hi Sean,

Thank you for the example code. It seems to work reliably enough for my use case. It was way easier than I imagined it being as I thought it might involve hacking the InMemoryRaster class. Would it be a desirable addition to make it easy for a user to do this in rasterio (at least a helper function generate the MEM string given an array)?

Wrapping the array in a Dataset does not seem to have much of a noticeable performance penalty if any at all. The performance of reading directly from the array (making a copy of any slices) and reading from the Dataset were almost identical.

Thanks again.
