aermap ¶

PyAERMOD AERMAP Input Generator

Generates AERMAP input files for terrain preprocessing. AERMAP is the EPA's terrain preprocessor for AERMOD.

AERMAP reads Digital Elevation Model (DEM) data and calculates: - Receptor elevations - Hill heights (for terrain-following calculations) - Source elevations

AERMAPDomain `dataclass` ¶

Domain definition for AERMAP processing

AERMAPReceptor `dataclass` ¶

AERMAPSource `dataclass` ¶

Source definition for AERMAP

AERMAPProject `dataclass` ¶

AERMAP project configuration

Generates terrain elevations for receptors and sources.

from_aermod_project `classmethod` ¶

from_aermod_project(aermod_project, dem_files: List[str], utm_zone: int = 16, datum: str = 'NAD83', buffer: float = 1000.0) -> AERMAPProject

Create an AERMAPProject from an AERMODProject.

Extracts source and receptor locations and builds corresponding AERMAP input for terrain elevation processing.

Parameters:

Name	Type	Description	Default
`aermod_project`	`AERMODProject`		required
`dem_files`	`list of str`	DEM file paths.	required
`utm_zone`	`int`		`16`
`datum`	`str`		`'NAD83'`
`buffer`	`float`	Buffer in meters around domain extents.	`1000.0`

Returns:

Type	Description
`AERMAPProject`

add_receptor ¶

add_receptor(receptor: AERMAPReceptor)

to_aermap_input ¶

to_aermap_input() -> str

write ¶

write(filename: str)

create_grid_receptors_for_aermap ¶

create_grid_receptors_for_aermap(x_min: float, x_max: float, y_min: float, y_max: float, spacing: float) -> Tuple[float, float, int, int]

Helper function to calculate grid parameters for AERMAP

Args: x_min, x_max: X coordinate range y_min, y_max: Y coordinate range spacing: Grid spacing in meters

Returns: Tuple of (x_init, y_init, x_num, y_num)
