We have worked with the San Francisco Fire Department and other agencies to provide a set of flattened data products. Flattening just means that we provide a single table representation of what is actually multiple tables in a relational database. In this case we are joining four tables in EAS. You can see the data model here. The flattening is accomplished using this database view.
Availability
The flattened data products are refreshed from our production system every weekday.
These data are available in the following locations
...
| available in version | column name | data type | description |
|---|---|---|---|
eas_address_base_id | int | eas primary key for base address table | |
base_address_num | int | ||
base_address_suffix | string | ||
base_address_create_tms | timestamp | ||
base_address_retire_tms | timestamp | ||
street_name | string | ||

eas_unit_address_id | int | eas primary key for unit address table | |
| longitude | double | ||

unit_address_base_flg | boolean | This is an artifact of the relational data model. If false, this is a typical unit address. If true, the unit_number value goes along with the base address (not typical). In the vast majority of cases, a base address will not have a unit number itself, even though there may be units for that address. | |
unit_address | string | The unit address number, letter, or fraction. For example: "A", "1/2", or "7". For legacy reasons, it is currently limited to 1 character. We are planning to expand it to 10 characters. | |

| unit_address_retire_tms | timestamp | ||
| 1.1.7 | map_block_lot | string | the map_block_lot field for parcels |
| block_lot | string | the block_lot (or assessor parcel number) field for a parcel | |
| 1.1.7 | parcel_date_map_add | date | the create date for a parcel |
| 1.1.7 | parcel_date_map_drop | date | the retire date for a parcel |
| eas_address_x_parcel_id | int | eas primary key to lookup parcels for a unit address | |
| address_x_parcel_create_tms | timestamp | the create time stamp for when a parcel was linked to an address | |
| address_x_parcel_retire_tms | timestamp | the retire time stamp for when a parcel was linked to an address | |
