Stereo Satellite Imagery involves the acquisition of images from two slightly different perspectives mimicking the human visual system’s binocular vision. This method is based on the parallax principle which states that objects appear to change in perspective and this parallax effect is used in satellite photography to produce a three-dimensional depiction of the Earth’s surface. …
Digital Elevation Models (DEM) and Digital Surface Models (DSM) are two fundamental elements in GIS landscape modeling where these models serve different functions and are essential in various applications, from environmental management to urban planning despite their seemingly interchangeable use. In this thorough investigation, one can explore the subtleties of digital surface models and digital …

Delineating and recording land parcels, along with their boundaries, ownership details and geographical characteristics is known as cadastral mapping. Establishing a thorough and accurate record of land ownership and use is the main goal to support effective land administration, taxation, and urban planning. In Geographic Information Systems, cadastral mapping is essential because it offers a …
The term “satellite imagery” describes the image of the Earth’s surface that is obtained by satellites in orbit and these photos are taken with sensors that record information at different wavelengths enabling the production of hyperspectral or multispectral imaging. These photos are fundamental datasets for mapping, tracking and examining the dynamic aspects of Earth in …
Geographic Information System technology is now widely used in many different industries with significant applications in civil engineering and the spatial viewpoint provided by GIS improves the planning, design, building and maintenance of civil engineering projects. This process will examine the complex network of GIS applications in civil engineering and how they transform how we …
Within the dynamic field of Geographic Information Systems, satellite technology is essential for gathering, analyzing and sharing geospatial data. The Korea Multi-Purpose Satellite (KOMPSAT) series is one such technological marvel that has been creating waves in the geographic information system business and the development of remote sensing and geographical analysis has been greatly aided by …
The process of producing precise and in-depth spatial representations of railroad infrastructure and its surroundings is known as “railway corridor mapping. To create detailed maps and models of railroad corridors, geospatial data must be collected, processed and analyzed. In the railway industry, these maps are an invaluable resource for planning, maintenance and operational decision-making. The …
What is a digital elevation model (DEM)? A Digital Elevation Model (DEM) is a representation of the bare ground (bare earth) topographic surface of the Earth excluding trees, buildings, and any other surface objects. GIS is based on Digital Elevation Models (DEMs) which are essential for landscape modeling, terrain analysis and other environmental applications where it …
Technological developments in the field of Geographic Information Systems (GIS) are always pushing the frontiers of investigation and analysis. Ground Penetrating Radar (GPR) is one such innovative technology. By looking beneath the surface of the Earth, this state-of-the-art technology provides a unique perspective that goes beyond typical GIS tools. We will examine the principles, uses, …
Within the field of Geographic Information Systems (GIS), encroachment management and detection have emerged as critical responsibilities for land administration, infrastructure development, and urban planning. Maintaining accurate geographical data and ensuring the effective use of land resources are significantly hampered by encroachment, which is commonly described as unauthorized entry onto another’s property. The complexities of …
