Project overview

Data collection in Yangon

• Road Network and building boundary data collection (existing)
• Road network, building boundary, POI collection from OSM
• SNS data and Geo-tagged photo collection
• Satellite imagery collection and processing (Yamamoto with the shared tool)

Data validation

• Transportation network data assessment tool for connectivity and error estimation

Modules / tools

• Road network creation from OSM - Upload to GitHub
• Download imagery - Shell script (args: two xy coordinates) - [x] Documentation - [x] Share tool
• Detect vehicles - Input: tiff - Output: Image, vehicle positions, georeferenced point - [x] Documentation and sample input and output - [x] Geo-referenced result
• Detect clusters of vehicle and transportation network - Road network (OSM) - Unit density (km/km^2) = Line length / spatial unit - (Accessibility (km/km^2) = Total distance accessible in one hour)
  • Vehicle detection
    • Number of vehicle (N/km^2)
  • Building detection
  • Area of Buildings
• Route API between POIs - Documentation - (Product)
• Web client application

Applications for urban problems
