🧭 What is GeoVisual Exploration?
GeoVisual Exploration (GVE) is the use of interactive visual tools and techniques to explore geospatial data. It allows users to visually discover patterns, relationships, and trends in maps and spatial datasets—especially when the data is complex or large.
💡 “GeoVisual Exploration turns raw spatial data into visual insight.”
🎯 Objectives of GeoVisual Exploration
-
To visually analyze spatial data without predefined hypotheses
-
To support exploratory data analysis (EDA)
-
To detect hidden patterns, anomalies, or clusters
-
To enhance user interaction with maps through zoom, filter, animate, and compare
🛠️ Key Features of GeoVisual Exploration
-
Interactivity
-
Users can zoom, pan, click, and filter layers
-
Data updates in real-time as users interact
-
-
Multiple Views & Coordination
-
Maps, graphs, and charts update simultaneously
-
E.g., Selecting a district in a map highlights its stats in a chart
-
-
Dynamic Querying
-
Filters like time range, population size, or rainfall amount can be applied
-
Enables customized data exploration
-
-
Animation & Time Sliders
-
Visualizing how patterns evolve over time
-
E.g., urban expansion, disease outbreaks, temperature changes
-
-
Linked Data Visualization
-
Combining spatial maps with statistical charts or histograms
-
Enables both spatial and non-spatial analysis
-
🌍 Real-Life Applications of GeoVisual Exploration (Nepal)
| Use Case | Description |
|---|---|
| Census Analysis | Visualizing population change by district with filters and comparison |
| Disaster Risk Mapping | Interactive landslide or flood hazard maps with village-level data |
| Tourism Mapping | Exploring tourist sites, trails, and facilities interactively |
| Health Surveillance | Tracking disease outbreaks (e.g., dengue, COVID) across time and location |
| Agricultural Planning | Exploring crop yield data with rainfall and soil type filters |
🧠 Tools Used in GeoVisual Exploration
| Tool / Platform | Functionality |
|---|---|
| Tableau / Power BI | Spatial dashboards, data filtering, charts + maps |
| Kepler.gl | Web-based tool for large geo datasets (open-source) |
| ArcGIS Dashboards | Interactive maps with real-time data |
| QGIS Plugins | TimeManager, Data Plotly for geo-visual analysis |
| Leaflet / D3.js | Custom coded interactive visualizations |
