Data Sources & Methodology
Primary source — City of Lethbridge Open Data (ArcGIS MapServer)
Available data — assessments, zoning
Provincial overlay — Alberta Regional Dashboard (regionaldashboard.alberta.ca) provides 54 socioeconomic indicators for all ~340 Alberta municipalities. Updated daily, cached 24 hours.
How data is collected — Municipal ArcGIS/Socrata endpoints are queried directly via REST APIs. Each municipality uses different field names for the same concepts (e.g. assessed value might be called TASS, assessed_value, ASSESSED_VALUE, or Total_Assessed_Value). We normalize these into a consistent schema. Regional dashboard data is fetched from the Government of Alberta's open data API and falls back to PostgreSQL snapshots during upstream outages.
What's not available — Business licences (only Edmonton & Calgary publish these via API). Building/development permits. Vacant lot tracking (only Stony Plain has a dedicated layer). Infrastructure project tracking. These data gaps exist because each municipality decides independently what to publish via their GIS systems.
Note: Parcel data includes 3-year assessment and tax history
