Understanding the Uncertain Geographic Context Problem (UGCoP): A Hidden Challenge in Spatial Analysis In spatial data science, we often trust the boundaries we work with — census tracts, zip codes, city limits — to define meaningful geographic contexts for analysis.…

Detailed Guide to Vector Data Formats in GIS What is Vector Data? Vector data represents real-world features using geometric shapes: Each vector feature also contains attributes (non-spatial data) like names, IDs, or categories. 1. Shapefile (.shp) Overview: Strengths: Limitations: Common…

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 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…

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…

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…
