Importing Bridger Data

Emissions Import

Used for importing Bridger emission data.

CSV Format

The following headers must be present in the CSV file, even though some of them can be blank:

Header	Type	Blank	Help
Plume image	String	YES	Each file referenced in this column must exist in the --data_path folder
Emission detected	Boolean	NO	(Yes/No) or (True, False)
Longitude	Number	NO
Latitude	Number	NO
Detection timestamp	Date	NO	ISO format
Detected rate	Decimal	YES	g/hr
Detection limit	PositiveInteger	NO	g/hr
Concentration	Decimal	YES	ppm*m

Notes:

• Owner column is required for self-reported emissions, but is optional for third party. If owner is present, any company found in the file must exist in the platform, or the import script will fail.
• Any additional fields will be stored as extra data object.

Script Arguments

In addition to the common arguments (environment, api_key, data_path), the Bridger script requires:

• --data_source - Source of the data: SELF_REPORTED, THIRD_PARTY, or EPA
• --contains_no_detects - Whether the data contains non-detects: 1 or 0

The following import parameters are set by the import script:

• data_provider: "Bridger"

Example

Example of calling the Bridger script on dev environment:

python -m importers.emissions.bridger --environment dev --api_key {API_KEY_VALUE} --data_path {PATH_TO_FOLDER} --data_source SELF_REPORTED --contains_no_detects 0

Nondetects Import

The Bridger nondetects import script can be used to import site non-detects using a CSV file.

CSV Format

The following headers must be present in the CSV file, and they cannot be blank:

Header	Type	Blank	Help
aershed_site_id	String	NO	Primary key of the Site database in the platform
time	DateTime	NO	ISO format
detection_limit_kgh	Number	NO	Detection limit in kg/h

Note: Any additional fields will be stored as extra data object.

Script Arguments

In addition to the common arguments, the nondetects script requires:

• --owner - The exact name of a company (must exist in the database)

Example

Example of calling the Bridger nondetect import script on prod-testing environment:

python -m importers.nondetects.bridger --environment staging --api_key {API_KEY_VALUE} --data_path {PATH_TO_FOLDER} --owner "A100"
