 Participatory GIS & Traditional Knowledge GIS

Participatory GIS & Traditional Knowledge GIS

In the era of high-tech satellites and AI-driven analytics, there’s a growing movement to ensure that the voices of local communities and indigenous peoples are not lost in the digital mapping revolution. Participatory GIS (PGIS) and Traditional Knowledge GIS (TK-GIS)…

 Uncertain Geographic Context Problem (UGCoP)

Uncertain Geographic Context Problem (UGCoP)

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.…

 Integration of Big Data and GIS

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 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

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…
