Library software like netCDF or HDF5 provides access to multidimensional data by array indices, but we would often rather access data by coordinates, such as points on the Earth's surface or space-time bounding boxes. This blog, with an accompanying iPython notebook, explores some issues with correctness and efficiency in accessing data by coordinates instead of array indices in a real-world example.
Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
