Type a natural language query like "analyze buildings in Plaka" or "wildfire risk for Evia". The AI understands Greek and English, geographic context, and analysis intent.
4egis classifies your query type, geocodes locations, and orchestrates the appropriate analysis pipeline — fetching elevation data, querying OpenStreetMap, running risk models, or joining statistical datasets.
Results render instantly as interactive map layers with hex grids, choropleths, or clustered markers. Layers auto-group by category (Hazard, Terrain, Demographic, etc.). Compact floating controls give quick access to settings, language, and account.
Generate publication-ready map exports with 10 professional templates, or download PDF reports with analysis steps, methodology, descriptive statistics, and AI narrative — all from a single click.
Comprehensive spatial analysis of any location in Greece. Extracts building footprints, street networks, points of interest, and land use zones. Computes 18+ GIS metrics including walkability score, building density, road network connectivity, and Shannon diversity index.
10-factor wildfire risk model using real DEM elevation data, vegetation cover, slope & aspect analysis (Horn's method), water proximity, road access, building density (WUI), Natura 2000 fuel load, seasonal drought index, and historical risk multipliers for known fire-prone regions.
7-factor flood risk model incorporating elevation, slope, aspect, impervious surface coverage, water body proximity, Natura 2000 wetland zones, and regional rainfall intensity. Generates hex-grid risk maps with boundary-clipped cells for accurate coastal analysis.
Optimal driving routes between Greek cities and locations. Uses OSRM (Open Source Routing Machine) with real road network data. Displays distance, duration, turn-by-turn geometry, and AI-generated travel insights.
Search and analyze Europe's largest network of protected nature areas. Identifies SCI (Sites of Community Importance) and SPA (Special Protection Areas) zones. Classifies designation types, calculates spatial coverage, and generates biodiversity reports.
Transform tabular data into interactive thematic maps. Supports choropleth, heatmap, dot-density, isoline, flow, cartogram, and cluster visualizations. 4 classification methods, 12+ color palettes, auto-grouped layer management, and multi-level administrative boundaries.
Toggle Copernicus Land Monitoring Service overlays: CORINE Land Cover, Tree Cover Density, Imperviousness, Water & Wetness, Grassland, Small Woody Features, and Natura 2000 land cover. Click any pixel for feature identification.
Publication-quality map exports with 10 professional templates (Classic, Modern, Academic, NatGeo, Surveyor, Presentation, Atlas Plate, Grid, Poster, Editorial). Configurable north arrow, scale bar, legend, coordinate grid, title block, and AI-suggested template selection. Export at up to A0 / 300 DPI. PDF reports include analysis steps, methodology, descriptive statistics (mean, median, std dev, IQR), and AI narrative.
