YAML Structure#

The root object is a sequence with the no tag applied.

Top-Level Keys#

Because the root object of counties.yml is a sequence, there are no top-level keys. Each sequence item, however, is a mapping with the following keys:

`state`	Name of the state containing the county in all uppercase letters.
`name`	Name of the county in all uppercase letters.
`fips3`	Portion of the county’s FIPS code as a string indicating only the county, not the state.
`number`	The number of the county as assigned by the state, if applicable.

Tags#

No tags are used in counties.yml.

Anchors#

No anchors are used in counties.yml.

Python Implementation#

The `CountyInfo` Class#

...

Generating `counties.yml`#

The YAML file can be automatically generated by running the ng911ok.lib.counties module directly from the command line.

Note

Be sure to run as a module (with the -m flag) rather than as a script, e.g.,

python -m ng911ok.lib.counties "path\to\data.gdb\county_feature_class" "path\to\write\counties.yml" -c COUNTY_NAME -f COUNTY_FIPS_NO -n COUNTY_NO -S OKLAHOMA

Hint

If ModuleNotFoundError: No module named 'ng911ok' is encountered, change the working directory to the top-level Toolkit directory (the parent of the ng911ok directory).
