This project creates an interactive web map visualization of Washington DC's 311 service request data using the Wt C++ web framework and Mapbox mapping technology.
Build Boost and Wt on a bash shell (Linux, Mac, Windows) with
./build.boost.sh
./build.wt.sh Build with
./build.cmake.sh Access the web interface at http://localhost:8080
- Interactive Map: Browse DC 311 service requests on an interactive Mapbox map
- Dual CSV Loading: Combines multiple CSV files for comprehensive data coverage
- Service Categorization: Color-coded markers by service type (potholes, street lights, trash, etc.)
- Ward-based Filtering: Filter requests by DC's 8 political wards
- Real-time Statistics: Dashboard showing request counts and distributions
The application processes DC 311 service request CSV files with 37 columns of data including:
- Geographic Data: Latitude/longitude coordinates for mapping
- Service Classification: Request types, responsible agencies, priority levels
- Status Tracking: Request lifecycle from submission to resolution
- Address Information: Street addresses, wards, zip codes
For detailed information about the CSV data structure and service codes, see DC311.md
The application automatically:
- Loads and combines multiple CSV files
- Validates geographic coordinates for DC area
- Categorizes service requests by type and agency
- Generates statistics by ward and service category
- Prepares data for interactive map visualization
