The city of Pontianak is located on the banks of the Kapuas River and is one of 23 regions in Indonesia that have experienced land subsidence so that the city has the potential to overcome tidal flood. The potential for tidal flood in some areas can be modeled using various data, such as DEMNAS data, DEM LiDAR data, sea level rise data, and land subsidence data. Tidal flood modeling can be done using spatial analysis of the four data. The sea level rise data and land subsidence data can be used to correct each DEMNAS data and DEM LiDAR data so that the final result can be determined which areas are affected for tidal floods and which areas cannot be affected by tidal floods. Tidal flood modeling is carried out for 2020, 2035, 2050, and 2100 in Pontianak City. From the results of tidal flood modeling in each year, it can be seen that from year to year the area of the area affected by tidal floods has increased. In addition to tidal flood modeling, this research can also be seen about the quality of DEMNAS data against DEM LiDAR data. To determine the quality of DEMNAS data against DEM LiDAR data, statistical calculations are performed to obtain the results that the quality of DEMNAS data against DEM LiDAR data is very low.
