<p><em>The characteristics</em><em> of the pattern of land subsidence need to be mapped for the purposes of planning and structuring the city as well as </em><em>taking appropriate actions in anticipating and mitigating </em><em>the</em><em> impact. </em><em>These characteristics can be determined by combining the land subsidence measurements done with various methods such as </em><em>levelling</em><em>, GPS, direct measurement and InSAR.</em></p> <p><em>Land subsidence</em><em> that occurred in Semarang ha</em><em>d</em><em> a</em><em> rate that varie</em><em>d</em><em> between 0 - 13 cm / year with an increasing trend towards the north east (northeast) of Semarang. The area</em><em>s</em><em> </em><em>which </em><em>ha</em><em>d</em><em> a</em><em> high rate of land subsidence between 9 -13 cm / year </em><em>included</em><em> PRPP, Tanjungmas, Terboyo and Kaligawe. </em></p> <p><em>In this paper will show spatial distribution of landsubsidence which have identical pattern  with the change of ground water level .Observations</em><em> GPS method has a high correlation with changes in ground water level reaches 0</em><em>.</em><em>956 compared with InSAR observations, GPS, direct observation</em></p>
