Define a 1x1 pixel read window starting at that index (see the tiny_window() function below) and use it to read an ndarray. Its functions typically accept and return Numpy ndarrays. For example, the SRTM data provide a digital elevation model of the Earth. >>>Python Needs You. filename str, rasterio. The reason for using RasterIO for this is that the parameters we use are directly mapped to the GDAL RasterIO function used (after adapting the 1-based offset index in R to 0-based offset in C++). Thanks, Mike. Both examples work well, but they are terribly inefficient and won't process a really big raster.
