Floods in Indonesia usually occur due to 2 factors, that is natural factors and anthropogenic factors. Amount of number of historical flood disaster data in Indonesia which is generally presented in tabulated form, it will be difficult to see the distribution of the flood locations. By using the spatial data of flood location modeling method that using ARCGIS, the spatial distribution of flood locations will provide information that relate which areas has flooded disaster. This modelling method is carried out with the aim of identifying the distribution of flood locations in Indonesia, presenting the distribution of flood locations in Indonesia based on historical flood disaster data and analyzing the level of flood incident in Indonesia. The results from modeling the spatial data distribution of flood incident in Indonesia, it was obtain that as many as 3,482 villages were impacted by flooding in 2 years period time, those are 2019 - 2020, Java Island became the area with the most frequent flood incident and Papua Island became the area with the rarest frequent number of flood incident in Indonesia in 2 years of period time.
