  • Government open geographic data increasingly abundant
  • Satellite imagery and AI recognition technology reducing data collection costs
  • Crowdsourcing models can quickly supplement and verify data

Lowered Technology Barriers:

  • Map libraries like Mapbox and Leaflet simplify development
  • Cloud services make large-scale data storage and querying easy
  • Static site generators reduce operational costs

Feasibility Analysis
