  6. Let’s Peek Inside! Integrating the Census Data API with ArcGIS Web Applications

  7. Joining APIs • FIPS as unique ID between APIs • Census data comes in as an array of rows (think CSV file) • Transform each row into an object with keys from first row • Didn’t need to actually create joint objects, but simple • ArcGIS Objects – add extra fields to attributes of each graphic • Census objects – add geometry to object Integrating the Census Data API with ArcGIS Web Applications

  8. Initial Issues My Server • Cross-domain requests – required a proxy on my web server • API limitations – only 5 variables per request • Working across multiple counties & states – separate API calls We Are Here Census Integrating the Census Data API with ArcGIS Web Applications

  9. Initial Issues My Server • Cross-domain requests – required a proxy on my web server • API limitations – only 5 variables per request • Working across multiple counties & states – separate API calls We Are Here APIs evolve (aka 1 year later) • CORS enabled Census API – cross domain solved • API limitations removed – fewer requests • Data Description tools in beta Census Integrating the Census Data API with ArcGIS Web Applications
