📋 Übersicht

ThemisDB bietet umfassende Risikobewertungsmodelle für Umweltrisiken und Anlagenrisiken, die vollständig mit deutschen Umwelt- und Sicherheitsvorschriften konform sind.

Enterprise Feature: Diese Risikobewertungsmodelle sind als Enterprise-Funktionen gekapselt und separat verfügbar.

Core Feature: Die 3D-Geospatial-Unterstützung (Point(x,y,z)) ist als Core-Feature in ThemisDB integriert.

Integration mit ArcGIS

Alle Risikobewertungen können direkt nach ArcGIS exportiert werden:

// 1. Risikobewertung durchführen
auto flood_risk = assessor.assessFloodRisk(area, params, 100);

// 2. Export nach ArcGIS
IArcGISDataProvider* provider = CreateArcGISDataProvider();
provider->connect("path=C:\\Data\\ThemisDB");

SpatialFeature feature;
feature.geometry = area;
feature.attributes.properties = flood_risk.detailed_findings;

// 3. In ArcGIS visualisieren
// Die Daten erscheinen automatisch in ArcGIS Pro/Server

Anwendungsbeispiele

        std::cout << "High flood risk: " << facility.facility_id << std::endl;
        
        // Export nach ArcGIS für Visualisierung
        exportToArcGIS(facility, risk);

);

// 2. Dominoeffekt simulieren
DominoEffectParams domino;
domino.primary_facility = incident_location;
