Open Data Minneapolis vs Urban Observatory
Open Data Minneapolis is the city's ArcGIS Hub portal, publishing GIS layers and non-spatial datasets — from 311 service requests to crime incidents — as a standard Esri Hub site. Its DCAT-US JSON feed and Hub search API expose the full catalogue for machine consumption at no cost and without a key.
Urban Observatory, run by Newcastle University, streams one of the UK's largest real-time urban sensor networks, covering air quality, traffic, flooding, and weather, from thousands of fixed and mobile sensors across Newcastle and partner cities. Its v2 API is fully keyless and exposes sensor locations and readings as JSON, CSV, or Shapefile, with bounding-box filtering for GIS tools. It's an academic, publicly funded service with no commercial tiers.
