Recent research has shown that understanding the physical nature of chromospheric oscillations hinges critically upon the understanding of the plasma structure in which they are formed and observed. To this end we discuss the mapping of the chromospheric plasma topography through the analysis of simultaneous SOHO/MDI and TRACE time-series observations through a combination of Fourier and Wavelet based analysis techniques. We are able to construct a picture of the chromospheric plasma and its interaction with the wave modes present. Such a picture will focus studies on topographic regions that will form a simulation test-bed for theories of modeconversion, dissipation and wave heating in the solar chromosphere.
