ABSTRACT:

This study presents the generation of high-resolution contour maps for selected areas within Satna district, Madhya Pradesh, through the integration of satellite-based remote sensing, GPS-enabled field data collection, and Geographic Information System (GIS) technologies. Primary spatial data-comprising geodetic coordinates and elevation-were collected systematically from two target sites: Santoshi Mata Pond and Dada Sukhendra Singh Stadium. The acquired data were processed using QGIS 3.42, Surfer 15, and Google Earth Pro to develop Digital Elevation Models (DEMs) and a series of derivative topographic products including contour maps, 3D surface and wireframe models, base maps, color relief and shaded relief maps and watershed delineations. The results validate the effectiveness of integrating fieldbased GPS surveys with satellite and GIS technologies for the accurate modeling of terrain features. The study confirms the applicability of this geospatial approach in supporting terrain evaluation, watershed characterization, hydrological analysis, and spatial planning. The methodology is transferable to various domains such as agricultural engineering, infrastructure design, resource management, and environmental assessment.
