Disclosed herein are various example systems, methods, and compositions, for extremely high-resolution in situ spatial analysis of a sample, with particular applicability to biological materials, by strategically multiplexing a. plurality of different imaging techniques. For instance, certain inputs can be configured to elicit multiple different types of output signals from the sample simultaneously, each of which encodes a different attribute of the sample.
