We present an optimized layout of horn positions for the Degree Angular Scale Interferometer (DASI), which provides good coverage of the u-v plane and 3-fold symmetry. We investigate how an optimal subspace filtering analysis of a single pointing of DASI could be used to determine the anisotropies in the cosmic microwave background over a range of angular scales near 30'. We discuss the complementarity between the angular scales probed by DASI and NASA's MAP satellite at 30GHz and strategies for imaging the sky at these frequencies. Finally, we quantitatively assess how well the angular power spectrum can be recovered by deconvolution of linear combinations of squares of the DASI visibilities.
