Notes

Records were geocoded using CEHI's AutomaticGeocodingTool_V1.99. Batch 1, records were matched with a minimum match score of 100 to one of three address locators: StreetMap Premium 2019's building-level locator (SMP_Pt19), StreetMap Premium 2019's street-level locator (SMP_St19), or Business Analyst 2013's street-level locator (BA_St), listed in order of decreasing priority. Batch 2, records were matched with a minimum match score of at least 90 to one of two address locators: StreetMap Premium 2019's street-level locator (SMP_St19), or Business Analyst 2013's street-level locator (BA_St), listed in order of decreasing priority. Batch 3, records were manually reviewed and matched to StreetMap Premium 2019's street-level locator (SMP_St19).
