Digital Soil Mapping of Geo-Technical Properties of Risalpur Cantonment

Abstract

Geo Technical properties vary from a place to another along width as well as depth of the soil stratum. The knowledge about spatial variations of these properties is indeed very helpful before executing a construction project. Therefore, this paper attempts to present an innovative computational based approach of mapping geotechnical properties of Risalpur Cantonment with the help of Geographical Information System (GIS). Soil samples collected through Standard Penetration Tests and Core Cutter Method at a depth of 5 feet were later tested in MCE Soil Laboratory to determine various soil properties including Atterberg Limits, Bearing Capacity etc. Thereafter, calculated results along with their precise coordinates i.e. Latitude and Longitude were used to prepare Digital Soil Maps (DSM) using Inverse Distance Weighting (IDW) tools available in ArcMap / ArcGIS. The authors are of the view that this research will prove to be very helpful in determining spatial variations in Geo-Technical properties within Risalpur Cantonment and forms a Digital Data Base of Soil Maps for future references
