WebFeb 14, 2013 · DTMF isn't used with ISDN. ISDN relies on bytes which contain the encoded digit. Not many people use ISDN for phone calls these days, by the way (some countries use it more). Restricted to phone calls, there is no "advantage" or "disadvantage" of DTMF - there is no other way to get the signal to the phone company if you're on an analog line. WebThe use of unmanned aerial vehicles (UAVs) has been steadily increasing due to their ability to acquire high-precision ground elevation information at a low cost. However, these devices have limitations in estimating elevations of the water surface and submerged terrain (i.e., channel bathymetry). Therefore, the creation of a digital terrain model (DTM) using UAVs …
