Abstract: The purpose of this study is to produce geotechnical maps as a tool for collecting, physical and engineering data on the soil of the city of Hilla (residential areas) by using Geographical Information System (GIS). The information is composed of field and laboratory tests and the importance of geotechnical maps used to give an idea of geotechnical properties of studying. In this study, 77 geotechnical maps were prepared for different depths reach to 10.5 m. These maps were prepared based on the reports of the National Center for Construction Laboratories (NCCl) as well AL-Mawal Company for Soil Investigation which included the period between (2006-2017) where the maps were based on the results of (115) test bore hole. Geotechnical maps show that the physical properties is percentage of Plastic Limit (PL) is between 7.10-41% and the Liquid Limit (LL) is between (11-64%). The wet density varied between 2.04-1.60 gcm-3 and the dry density between 1.13-2.30 gcm-3 while moisture content ranged values 4.10 -31.8%). Also the geotechnical maps show that the engineering properties: the maximum soil bearing capacity reached in depth (4 m) at hole within location in street 60 and the values of Standard Penetration Test (SPT) (2-57 blows) while the cohesive value is between 0.25- 5.77 Tm-2, friction angle value (0-43°). These values are randomly distributed at different depths on the soil of the city of Hilla.
