Abstract—In the area of Banjarmasin City, a lot of data has been obtained well based on CPT data or SPT data. But for now, there is no information that summarizes the depth of hard soil in the city of Banjarmasin, especially in the form of digital maps. In in the field of civil engineering, the use of GIS has been widely applied to help map depth and type of soil. There has been a lot of research done using the CPT data and the GIS application. This kind of map holds important value for field work practice, especially in civil engineering. Therefore, it is necessary to make an initial concept of a digital map that can later be used as a starting point for foundation work in the city of Banjarmasin. The result of this study is a map of the depth of hard soil in the city of Banjarmasin with the help of GIS software. From the results of soil depth data based on CPT and SPT point test, the depth distribution of hard soil in the city of Banjarmasin varies from 28 m to 42.4 m. For areas that are not covered by the test location, a linear interpolation method is used. This depth varies in each region, between 30-40 m in Banjarmasin Utara, 36-42.4 m in Banjarmasin Barat, Banjarmasin Selatan, and Banjarmasin Tengah, and 28-40 m in Banjarmasin Timur.
Index Terms—Depth, hard soil, CPT, map.
