PREPARATION OF A GNSS RECEIVER FOR RTK SURVEYING USING SURPAD 4.0 TO IDENTIFY RAINWATER ACCUMULATION AREAS IN SAMARKAND CITY
This article examines the identification and geodetic investigation of rainwater accumulation areas in the city of Samarkand. The
study describes the process of preparing a GNSS receiver for Real-Time Kinematic (RTK) surveying using the SurPad 4.0 software,
including device configuration, input of base station and rover parameters, and methods for obtaining high-precision coordinates.
Based on RTK technology, geospatial data were collected to identify low-lying areas prone to rainwater accumulation, determine
their precise coordinates, and develop a digital terrain model. The obtained results can be applied to urban drainage planning, flood
risk assessment, and the improvement of geodetic surveying accuracy.
