Geocoding | |
ESRI | |
 Level 1: address searches likely to result in either precise coordinates or interpolated location along street for address | 42 (23.0%) |
 Level 2: address searches often result in precise coordinates or interpolated location along street, but sometimes street-level coordinates or coarser | 16 (8.7%) |
 Level 3: address searches sometimes result in precise coordinates or interpolated location along street, but more often street-level coordinates or coarser | 51 (27.9%) |
 Level 4: address searches result in imprecise locations, e.g. centroids of higher-level administrative boundaries | 74 (40.4%) |
