    An ECDIS is a unified navigational information display which presents on an updated chart background,updated route,present position and fast track, combining these as approprite with radar,ARPA and other navigational sensors in order to improve safe navigational through the clear display of the situation in the vicinity of the ship.
    chart can be corrected through a floppy disc,compact disc, even directly through the satellite systems. The latest system of updating charts is that the manufacturer transmit the chart updated as broadcast in coded format. Dedicated software is fitted in the ECDIS which will receive these updates,decode them and correct the charts.

                        The Change in ships trim when being at motion or being stationary is called squat. The Squat is mainly experienced over in shallow waters it increases with square of the speed of the ship in order to reduce squat ship speed has to be reduced squat is calculated by the formulae
                        squat= V(square)/100*Cb

                            Squat is a bodily sinkage of a ship due to its movement through the water and is depend on speed, ship form, and the underwater clearance.
                            The overall decrease in the underkeel clearance fwd. and aft is called squat.

                            TO ELIMINATE SQUAT;
                            reduce speed,
                            Sufficiant UKC is to be kept to avoid SQUAT.

                                    Vector charts are more advantageous than raster chart because vector chart enables user to select many alarms, such as depth alarms, various modes such as head up and north up, Zooming facility, Add or remove the data required.

                                      raster charts are  copy of paper charts whereas vector charts are electronic charts.

                                                      Phasing:
                                                      Phasing is a method used in echo sounder to determine depth of the sea bottom. In this method the speed of the stylus is kept constant and the range scale is changed from 0-100 mtrs , 100-200 mtrs , 200-300 mtrs and so on. It is important that the echo sounder range changed and regularly checked.

                                                      Ranging:
                                                      Ranging is technique were the scale of the echo sounder is kept constant and the stylus is varied according to the depth scale chose. E.g.- 0-100, 0-200, 0-300 mtrs ans so on
