Integration of Big Data and GIS

Big Data refers to datasets so large, fast, or complex that traditional data-processing methods struggle to handle them. It is commonly characterized by the “3Vs”: volume (extreme size), velocity (rapid generation and processing), and variety (diverse formats). Geographic Information Systems…

3D GIS and Digital Twins

3D GIS refers to geographic information systems that represent and analyze spatial data in three dimensions (including height/elevation). It enables realistic 3D maps and models of the natural and built environment, enhancing decision-making. For example, Esri notes that 3D GIS…

UAVs (Drones) in GIS Data Collection

Unmanned aerial vehicles (UAVs, or “drones”) have become powerful tools for collecting geospatial data for GIS. Fitted with advanced sensors, UAVs can rapidly capture high-resolution imagery and 3D data over targeted areas. This enables a wide range of applications across…

AR and VR in Geographic Information Systems

Augmented Reality (AR) and Virtual Reality (VR) are increasingly being integrated with GIS to create immersive, spatially-aware experiences. AR overlays digital information (maps, models, data) onto the real world using devices like smartphones or headsets, while VR immerses the user…

FME (Feature Manipulation Engine) by Safe Software

FME is a no-code data integration platform (by Safe Software, Canada) focused on geospatial ETL. Originally a “Feature Manipulation Engine” for GIS data, it now handles both spatial and non‑spatial data. FME Desktop (formerly FME Form) provides a visual Workbench…

Scripting and Automation in GIS

Geographic Information Systems (GIS) increasingly rely on scripting to automate repetitive tasks, ensure reproducibility, and integrate complex analyses. The dominant scripting language in GIS is Python, which is supported across both proprietary and open-source platforms. Python libraries (standard and third-party)…
