Map Attribution Notice

Our property search platform utilizes map data that requires proper attribution to OpenStreetMap contributors, ESRI, and related data providers.

OpenStreetMap Data

Our interactive property search maps are powered by OpenStreetMap (OSM), a collaborative project to create a free editable map of the world. OpenStreetMap is built by a community of mappers who contribute and maintain data about roads, trails, cafés, railway stations, and much more, all over the world.

Key Characteristics:

Community-driven, crowdsourced mapping data
Free and open data under ODbL license
Global coverage with varying detail levels
Real-time updates from contributors worldwide

ESRI Data

Our platform also incorporates ESRI (Environmental Systems Research Institute) mapping services, providing additional geographic data layers and spatial analysis capabilities. ESRI offers comprehensive commercial mapping solutions that complement our OpenStreetMap foundation.

Key ESRI Services:

ArcGIS Online basemaps and imagery
Geocoding and reverse geocoding services
Spatial analysis and routing capabilities
Demographic and boundary data layers

Integration Benefits:

Enhanced data accuracy through multiple sources
Professional-grade mapping reliability
Comprehensive geographic coverage
Advanced spatial analysis features

Technical Implementation

We implement map data through the following technical stack:

OpenStreetMap Implementation:

AWS Amplify UI Geo with MapLibre GL
Vector tiles for optimal performance
Custom styling for property search use cases

ESRI Implementation:

ArcGIS API integration for enhanced data
Multiple basemap layers and imagery
Professional geocoding services
Spatial analysis and routing tools

Data Processing:

Geocoding via AWS Location Service & ESRI ArcGIS
Property location data integration
Spatial indexing for search performance
Multi-source data validation and reconciliation

License & Attribution Requirements

Our mapping services utilize data from multiple providers, each with specific licensing requirements:

OpenStreetMap Licensing:

Data Quality & Limitations

While OpenStreetMap provides comprehensive global coverage, users should be aware of certain limitations:

Coverage Variations:

Urban areas typically have higher detail levels
Rural areas may have limited mapping detail
Data recency varies by region and contributor activity

Usage Considerations:

Map data should be cross-referenced with official sources
Property boundaries may not reflect legal descriptions
Road networks and features are subject to change
